2.4 Instructions for Use of the G4-S3

The instructions for use of the G4-S3 are given below.

(1) When the MELSEC-A series CC-Link system Master/local module is used, a
"communications error" may occur in rare cases on the peripheral device device
side connected to the G4-S3. Check the following points and take a proper action.

(a) Among the factors in occurrence of a "communications error" is the frequent

execution of the FROM/TO instruction by the PLC CPU for the buffer memory
of the MELSEC-A series CC-Link system Master/local module.
The MELSEC-A series special function module gives priority to access
from the PLC CPU in processing. Therefore, making frequent access to
the buffer memory not only increases the scan time of the PLC CPU but
also causes a delay in processing of the special function module, leading
to the factor in occurrence of a "communications error".
When the MELSEC-Q or QnA series CC-Link system Master/local module
is used, the above factor will not cause a "communications error".

(b) When making access to the buffer memory of the MELSEC-A series CC-Link
system Master/local module, add the normally closed contact of the input
signal (XnC) of the same module to the contact of the FROM/TO instruction
as a corrective action for a "communications error".
(XnC: FROM/TO instruction enable/disable signal. When XnC is OFF, the
FROM/TO instruction is enabled for execution.)
Adding the N/C contact of XnC allows normal data communications.

(2) One time of access from the MELSEC PLC programming software to the PLC
ends after several communications depending on the processing.
For example, when the PLC is monitored, several communications are made to
perform one time of monitor processing, and monitor processing communications
are repeated until monitor ending operation is performed.
Access to PLC CPUs on different networks will cause a considerable delay
depending on the number of stations to be accessed and access conditions.
The following example gives the guidelines of access time for accessing the
PLC CPU via CC-Link.
The access time is about 40 seconds in all cases.

Item Description
CC-Link system Only the Master station and G4-S3 are connected.
Accessed PLC CPU Q12HCPU (STOP status) of the Master station
Conditions • CC-Link system : 10Mbps
Data transmission rate • Between G4-S3 and peripheral device : 19200bps
(GX Developer Version 6 or later used)
Access made Read/write of sequence program (10k steps)

(3) The online operation performed from the peripheral device via the G4-S3 should
be started when the L RUN LED of the G4-S3 is ON.
You cannot perform online operation while the L RUN LED is off.
The L RUN LED of the G4-S3 is ON when the initial communication of the
CC-Link is complete.

(4) While the G4-S3 is operating, the DIP switches (SW1, SW6) can be used to
change the operation mode.
Also, before changing the operation mode of the G4-S3 to the "QnA mode", match
the transmission speed setting of the G4-S3 to that of the peripheral device side
software and start up the G4-S3.

When the L ERR. LED is ON or flickers at intervals of 2, 4, 6 or 8 seconds, make sure

that.
1) The CC-Link dedicated cable is not connected to the G4-S3 (if connected,
disconnect).
2) The operation setting DIP switch SW8 of the G4-S3 is set to ON (test mode) and
the station number setting switches are set to 0.
3) The peripheral device connection cable is not connected to the G4-S3 (if
connected, disconnect).

Then, perform the hardware test again. If the L ERR. LED is still ON or flickers at 2, 4,
6, or 8-second intervals after the test, the possible cause is a hardware fault. Consult
your sales representative.

(Step 6)
Power supply off the G4-S3, disconnect the RS-422 single-station loopback cable,
and set the operation setting DIP switch SW8 to OFF.
Set the station number setting switches to the station number assigned to the G4-S3

OR EARLIER

This chapter provides precautions for using the following MELSEC PLC programming
software other than GX Developer Version 5 or earlier to access the PLC CPUs, how
to operate the following software, and other information.
(MELSEC PLC programming software which will be explained)
• GX Developer Version 5 or earlier
• GPPQ
• GPPA

POINT
(1) When using the MELSEC PLC programming software explained in this chapter,
access to the QnACPU or ACPU can be made.
(2) Before starting online operations from the peripheral device, set the operation
mode of the G4-S3 according to the accessed PLC CPU.
(The QnA or A mode can be set as the operation mode of the G4-S3. You
cannot set it to the Q mode to access the PLC CPU.)
(3) Use GX Developer Version 6 or later to make access to the QCPU (Q mode) or
to the ACPU/QCPU (A mode) of the other station (coexistence network).

6.1 About the QnA mode and A mode

6 When the MELSEC PLC programming software used is other than GX Developer
Version 5 or earlier, the operation mode must be set to the QnA or A mode using the
operation setting DIP switches on the G4-S3 front.
Set to either mode after considering the following conditions.

(1) Condition for choosing the QnA mode

When the access target is the QnACPU, set the G4-S3 to the QnA mode.

(2) Condition for choosing the A mode

When the access target is the ACPU or QCPU (A mode), set the G4-S3 to the A
mode.
Access can be made to only the ACPU on CC-Link where the G4-S3 is
connected.

POINT
The accessible PLC CPU depends on the MELSEC PLC programming software
used.
Refer to Section 2.3(3) for details.
