Processing This module FB reads the cyclic data of the Class 1 service from the DP-Slave using one request instruction out of eight usable request
instructions.
When i_bEN (execution command) is turned on, it executes the READ service request/response processing using the request instruction
specified with i_uRequestInstructionNo (request instruction number) to the DP-Slave specified with i_uFDLAddress (FDL address).
Upon receipt of a response from the DP-Slave, o_bOK (normal completion) is turned on.
In the event of a response error, o_bErr (error completion) is turned on, and o_uErrID (error ID) and o_u3DetailedErrorCode (error details)

Precautions • Before using this module FB in the program, update the PROFIBUS labels. ( MELSEC iQ-R PROFIBUS-DP Module User's Manual
(Application))
• This module FB does not include the error recovery processing. Program the error recovery processing separately in accordance with
the required system operation.
• Turn off i_bEN (execution command) after o_bOK (normal completion) or o_bErr (error completion) turns on. By turning off i_bEN
(execution command), o_bOK (normal completion) and o_bErr (error completion) are turned off, and o_uErrID (error ID) is cleared to 0.
• Acyclic communication has eight request instructions. Data of each channel can be read/written from/to the DP-Slave at a specified
timing independently of data exchange.

Error ID
The status code of RJ71PB91V is stored in o_uErrID (error ID). ( MELSEC iQ-R PROFIBUS-DP Module User's Manual

Processing This module FB provides the DP-Master with notification of extended diagnostic information or notification of correction of the relevant
error that has occurred during data exchange.
Notification of extended diagnostic information or notification of correction of the relevant error is requested when i_bEN (execution
command) is turned on.
• When the data length of extended diagnostic information is set to other than 0, extended diagnostic information is notified.
• When the data length of extended diagnostic information is set to 0, correction of the relevant error is notified.
When the processing is completed successfully, o_bOK (normal completion) is turned on.
When the processing is completed with an error, o_bErr (error completion) is turned on, and an error code is stored in o_uModuleErrId
(error code).
Processing is stopped when i_bEN (execution command) is turned off before the sending of the module FB is completed. However,
notification of extended diagnostic information may be completed depending on the timing of the stoppage.
