DG DG DG
SLD Special cable SLD Special cable SLD
FG for CC-Link FG for CC-Link FG

3.3.2 Notes on cable connection

(1) Concerning the special cable for CC-link, Version 1.00 and Version 1.10 should not be used together. If a Version 1.10 cable
is mixed with a Version 1.00 cable in use, all cables are regarded as Version 1.00. In that case, however, normal data
transmission cannot be guaranteed.
Connect the shielding wire of a special cable for a CC-link to the "SLD" of each unit, pass it through "FG" and carry out the
D type (the 3rd grade) or higher type grounding on both ends of it.
Ensure that the D type (the 3rd grade) or higher type grounding for each FG terminal is carried out. If you fail to do so, the
instrument may not operate correctly.
SLD and FG are connected inside the body of the SR83.

3.4.2 Matters to be attended to in wiring

• One of the requirements for enabling the SR83 to function thoroughly to establish a highly reliable system is external wiring
that is not easily affected by noise. The following are matters to be attended to in performing external wiring.
(1) Use separate cables for AC and for the special cable for CC-Link to keep it unaffected by surge or induction on the AC side.
(2) The external line should not be bundled with or installed adjacently with a load line except those from the main power circuit
line, a high voltage line and the sequencer. Otherwise it will easily be affected by noise, surge or induction.
(3) For a shielding wire or a shielded cable, one-point grounding should be carried out on the sequencer side. Depending on the
condition of external noise, however, it may be better to ground on the external side.

Warning
● The SR83 should be used in environmental conditions as stated in the general specifications in its instruction manual.
If it is used in any environment other than that noted in the general specifications, this could cause an electric
shock, fire, erroneous operation, damage to the product or deterioration of its functionality.
● Do not directly touch a conductive part or an electronic component of the SR83 while it is energized.
This could create an electric shock, erroneous operation or other failure.

Caution
● Make sure to ground the FG terminal using the D type (the 3rd grade) or higher grounding. If not, erroneous
operation could result.
● Wire the SR83 correctly after confirming the rated voltage of the product and the terminal arrangement.
Connection to a power source with voltage different from the rated one or with erroneous wiring will create a fire
hazard or failure of the apparatus.
● Tighten the terminal screws within a torque range of M3.5 1.0N•m (10kgf•cm).
(1) If a terminal screw is not sufficiently tightened, it will lead to a short or erroneous operation.
(2) If a terminal screw is tightened excessively, the screw will be broken and it will lead to a short or erroneous
operation.
● Take care not to allow foreign matter, such as the cutting powder from wire chips, to get into the unit. This can
lead to fire, failure or erroneous operation.

-5-
3.5 Maintenance and inspection
Although there is no particular inspection item for the SR83, check the inspection items as described in the Mitsubishi Electric
Corporation Sequencer CPU User's Manual so that your system can always be used under optimal conditions.

Warning
● Do not touch a terminal while the instrument is energized.
This can result in an electric shock or erroneous operation.
● Before cleaning or tightening a terminal screw further, make sure to externally turn off power for all phases.
Without cutoff in all phases, trouble or erroneous operation of the SR83 can result.

Caution
● Do not disassemble or remodel the SR83.
This can lead to trouble, erroneous operation, an injury or a fire.
● The case of the SR83 is made of a plastic resin. It should not be allowed to fall or receive impact shock.
This could result in serious damage to the SR83.
● Mount or remove the SR83 on/from the panel only after turning power off externally for all phases.
Without cutoff in all phases, trouble or erroneous operation of the SR83 could be the result.

Chapter 4 Setting before operation and procedure
4.1 Sequencer setting
When SR83 setting is carried out through the CC-Link, the SR83 has to be regarded as a remote device occupying one station.
Accordingly, CC-Link setting should be carried out in consideration of the number of units to be connected and the number of
possessory stations.

4.2 SR83 parameter setting

There are three types of communication-related parameters for the SR83 as listed below and these parameters are unable to be
changed through communication, that is, they should be set by key operation on the front panel.
For setting, follow the procedure by referring to the key sequence shown in the instruction manual of the SR80 Series.

● Communication address (station No.) setting screen 1-30

When the SR83 sets a station No., a data area to store information on I/O signals for control and read or written data is defined.

Initial value: OFF

Setting range: OFF, 1 ~ 64 (Setting OFF means resetting.)

● Communication (transmission) rate setting screen 1-31

The speed of data transmission between the SR83 and the master station is set.

Initial value: 156 kbps

Setting range: 156k, 625k, 2.5M, 5M, 10Mbps
: 156k, : 625k, : 2.5M, : 5M, : 10M

● Setting of communication mode 1-29

(1) A mode for the master station to write data by extended setting or the like is selected.
(2) A communication mode should be set as an extended setting. This means that a change of setting from the local mode (LOC)
to the communication mode (COM) is not possible from the front panel.
Front key operation allows only the change from the communication mode (COM) to the local mode (LOC).
(3) The communication mode setting enables writing in the communication mode (COM) or the local mode (LOC) by extended
setting.
Initial value: LOC
Setting range: LOC, COM
: Local mode; only extended display through CC-Link communication
is effective.
: Communication mode; extended display and extended setting through
CC-Link communication are effective.

● Status lamp on front panel

The status lamp is provided on the right-hand side of the front panel display of the SR83. This lamp lights when the CC-Link
is in the status of RUN and goes out when it is not in communication.

4.3.2 Notes on sequencer programming

● Procedure of requesting initial data processing
This section describes the SR83 action in response to the application of power, a station number change and a communication
rate change, and presents the basic timing of a request for initial data processing.
1 When power is applied or a station number or a communication rate is changed, the SR83 turns the "initial date
processing request flag" RX(n+1)8 of the remote input/output ON.
2 The "initial data processing finish flag" RY(n+1)8 is turned ON by a higher order sequence.
3 Seeing the "initial data processing finish flag" RY(n+1)8, the SR83 turns the initial date processing request flag"
RX(n+1)8 OFF.
4 "Remote READY" RX(n+1)B is turned ON.
5 RY(n+1)8 is turned OFF by the higher order sequence.

4.4.1 Remote input and output functions

● Remote input (Remote → Master)
The remote input area comprises the following:
(1) Event 1 and 2 alarm statuses
The statuses of the event 1 and 2 actions are shown. The RXnO and RXn1 bits turn ON when the event alarm is in action and
the RXnO and RXn1 bits remain OFF when the event alarm is stopped or the optional event alarm function is not added.
(2) Burnout status
The RXn2 bit turns ON when scaleover happens at the higher or lower limit of PV or a cold point compensator goes into
trouble. It remains OFF in normal action.
(3) Heater break alarm
The action status of the heater break alarm is shown. The RXn3 bit turns ON when the heater break alarm is in action and it
remains OFF when the event alarm is stopped or the optional event alarm function is not added.
(4) PID/AT
The status of execution of auto-tuning is shown. The RXn4 bit turns ON when auto-tuning is in execution and it remains OFF
during PID control.
(5) Communication mode
A communication mode is shown. The RXnA bit remains OFF in the local mode and it is ON in the communication mode.
(6) Status of remote register selection
The status of remote register selection is shown when a set value of temperature SV is set by using either the RWwm area or
extended setting. The RXnB bit turns ON when extended setting is selected and it turns OFF upon selection of the remote
register (RWwm).
(7) Remote register (RWwm) error flag
An error status in setting an SV value by using the RWwm is indicated. If an SV value is set in the local mode of
communication, a set value is out of the setting range or auto-tuning is in execution, the RXnE bit turns ON and it turns OFF
when setting is accomplished normally.
(8) Input area related to extended display/extended setting
A display or the like can be changed by using the RW area while "hand-shaking" with the SR83 and input flags for such hand
shaking are allocated to RXnC and RXnD.
For details, see 4.6 "Extended display and extended setting."
(9) System area
Remote input called the system area is allocated to RX(n+1)8 ~ RX(n+1)B. This is the interface area between the CC-Link
supported devices and the master module.

● Remote output (Master → Remote)

The remote output area comprises the following.
(1) Setting numbers for extended display and extended setting
In the remote register area, an item to be input or output can be changed from the user sequence by using a setting number
and a hand shaking bit.
Such a remote register is defined as an extended area. Input is called display and output is called setting.
Areas in which a command number is written to decide for what purpose the extended area is used are secured in RYn0 ~
RYm5 and RYn6 ~ RYnB. RYnC, RXnC and RXnD are used as flag areas for such hand shaking.
For details, see 4.6 "Extended display and extended setting."
(2) System area
Remote output called the system area is allocated to RY(n+1)8 ~ RY(n+1)A. This is the interface area between the CC-Link
supported devices and the master module.

4.5 Remote register
The SR83 has a remote register for exchanging data with the master unit. The allocation of the remote register and the structure of
data are described in the following.

4.5.1 Remote register function

● Remote register area: RWr (Remote → Master)
This area is used as an input area when viewed from the master unit.
The register operates differently depending on the setting of the SR83 as described in the following.
(1) Measured temperature value (PV): (standard)
It processes communication with the SR83 asynchronously with the master unit sequence and stores measured temperature
values (PV) read regularly in the remote register.
(2) Control output value (OUT1): (standard)
It processes communication with the SR83 asynchronously with the master unit sequence and stores output values (OUT1)
read regularly in the remote register.
(3) For extended display
For details, see 4.6 "Extended display and extended setting."

● Remote register area: RWw (Master → Remote)

This area is used as an input area when viewed from the master unit.
The register operates differently depending on the setting of the SR83 as described in the following.
(1) Set temperature value (SV)
It processes communication with the SR83 asynchronously with the master unit sequence and writes set temperature
values (SV) stored regularly in the remote register.
(2) For extended setting
For details, see 4.6 "Extended display and extended setting."

4.5.2 Allocation of remote register

Measured temperature values (PV), output values (OUT1) and extended display values are stored in the remote register addresses
RWrn ~ RWrn+3, channel by channel, while set temperature values (SV) and extended setting values are stored in the remote
register addresses RWWm and RWwm+3, channel by channel. Values are in binary notation with 16-bit codes. (Negative digital
values are noted by complements of 2.) The allocation of remote register is shown in Table 4.3.

Table 4.3. Allocation of remote register

Direction of
data transfer Address Description Default value

RWwm Set temperature value (SV) 0

Master RWwm+1 Unused
→Remote RWwm+2 Unused
RWwm+3 Extended setting 0
RWrn Measured temperature value (PV) 0
Remote RWrn+1 Output value (OUT1) 0
→Master RWrn+2 Unused
RWrn+3 Extended display 0
m, n: Addresses given to master unit by station number setting

Don’t read or write to the unused remote register addresses.

When read or written, the SR83 processes nothing and you should not use them for safety’s sake.

- 12 -
4.6 Extended display and extended setting
(1) For extended display and extended setting, the remote output area and the extended area in the remote register are used and
changing of set values and reading of data are carried out from the master unit.
(2) A set value is changed or data is read once for the SR83 in response to each request for extended display or extended setting.
(3) When display or setting is carried out, parameters should be set in the remote register.
(4) A setting number and parameters should be set before scanning to be carried out simultaneously when the "extended display
flag" or the "extended setting flag" is turned ON.
For details of parameters, see 4.6.2 "List of extended display/extended setting."

4.6.1 Outline of extended display and extended setting

● Procedure of extended display
The following is basic timing of extended display.
1 The extension number of a desired display selected from the list of extension numbers is written, in the binary notation, by a
higher sequence in the "extended display setting numbers" RYn0 ~ Ryn5 of remote I/O.
2 The higher sequence turn the "extended display flag" RYnC of remote I/O ON.
3 The SR83 turns the "remote READY" RX(n+1)B of remote I/O OFF.
4 The SR83 turns the "extended display finish flag" RXnC of remote I/O ON.
5 After confirming that the "extended display finish flag" RXnC has been turned ON, the higher sequence turns the "extended
display flag" RYnC OFF.
6 The SR83 turns the "extended display finish flag" RXnC of remote I/O OFF.
7 If an error arises, the SR83 turns the "error status flag" RX(n+1)A of remote I/O ON. In case it is not turned ON, proceed to 11 .
8 When "extended display finish flag" RXnC of remote I/O is ON, the higher sequence turns the "error reset request flag"
RY(n+1)A ON.
9 The SR83 turns the "error status flag" RX(n+1)A OFF.
10 The higher sequence turns the "error reset request flag" RY(n+1)A OFF. (To know the contents of the error, read an error
code on an extended display.)
11 The SR83 turns the "remote READY" RX(n+1)B of remote I/O ON.
12 You can read display data on the "extended display" RWrn+3 of remote register through the higher sequence. (In the event
the "error status flag" is turned ON, a previously displayed data remains in the remote register RWrn+3.)

● Procedure of extended display
The following is basic timing of extended display.
1 A desired extension number selected from the list of extended setting numbers is written, in the binary notation, by a higher
sequence in the "extended setting numbers" RYn6 ~ RYB of remote I/O.
2 The higher sequence writes data of setting in "extended setting" RWwn+3 of remote register.
3 The higher sequence turns the "extended setting flag" RYnD ON.
4 The SR83 turns the "remote READY" RX(n+1)B of remote I/O OFF.
5 The SR83 turns the "extended setting finish flag" RXnD ON.
6 After confirming that the "extended setting finish flag" RXnD has been turned ON, the higher sequence turns the "extended
setting flag" RYnD OFF.
7 The SR83 turns the "extended setting finish flag" RXnD OFF.
8 If an error arises, the SR83 turns the "error status flag" RX(n+1)A of remote I/O ON. In case it is not turned ON, proceed to 12 .
9 When the "error status flag" RX(n+1)A is ON, the higher sequence turns the "error reset request flag" RY(n+1)A ON.
10 The SR83 turns the "error status flag" RX(n+1)A OFF.
11 The higher sequence turns the "error reset request flag" RY(n+1)A OFF. (To know the contents of the error, read an error
code on an extended display.)
12 The SR83 turns the "remote READY" RX(n+1)B of remote I/O ON.

● Procedure of reading error code during extended display/extended setting
In the event an error arises on an extended display, the previous extended display value remains in the remote register
RWrn+3. (In the case of start-up, it will be 0.)
If an error arises in the extended setting, there will be no writing. Data in the remote register RWwn+3 remains unchanged.
1 The extended display number 61 is written, in the binary notation, by a higher sequence in the "extended display numbers"
RYn0 ~ RYn5 of remote I/O.
2 The higher sequence turns the "extended display flag" RYnC ON.
3 The SR83 turns the "remote READY" RX(n+1)B of remote I/O OFF.
4 The SR83 turns the "extended display finish flag" RXnC ON.
5 After confirming that the "extended display finish flag" RXnC has been turned ON, the higher sequence turns the "extended
display flag" RYnC of remote I/O OFF.
6 The SR83 turns the "extended display finish flag" RXnC OFF.
7 The SR83 turns the "remote READY" RX(n+1)B of remote I/O ON.
8 You can read the error codes read into the remote register RWrn+3 by the high sequence. For the error codes, refer to "Table
5.1 Error code list."

● Procedure of extension table switching

It is possible to change the extension table number even when communication is in the local (LOC) mode.
1 The extended setting number 63 is written, in the binary notation, by a higher sequence, in the "extended setting numbers for
setting" RYn6 ~ RYnB of remote I/O through.
2 An extension table No. 0 or 1 is written in the remote register RWwn+3.
3 The higher sequence turns the "extended setting flag" RYnD ON.
4 The SR83 turns the "remote READY" RX(n+1)B of remote I/O OFF.
5 The SR83 turns the "extended setting finish flag" RXnD ON.
6 After confirming that the "extended setting finish flag" RXnD has been turned ON, the "extended setting flag" RYnD of
remote I/O is turned OFF.
7 The SR83 turns the "extended setting finish flag" RXnD OFF.
8 The SR83 turns the "remote READY" RX(n+1)B of remote I/O ON.

Chapter 5 Troubleshooting
5.1 Extended display/extended setting data error codes
(1) When extended display data is read from the sequencer CPU or data is written in the extended setting, the SR83 checks
specifications, whether or not of optional functions, write mode, execution command, range of data and the like and if an
error arises, it stores an error code in a 16-bit binary value through extended display in the the remote register RWrn+3.
For details of error codes, please refer to Table 5.1 Error code list.
(2) For resetting the error codes, turn the "error reset request" RY(n+1)A ON, and the SR83 turns the "error status flag"
RX(n+1)A OFF.

Details of error codes
