R5REQ Function Module 5-3
5.2.2 Output Parameters
Parameter Att. Description
P4 W Fault message
Basic status and error codes, which the R5REQ identifies when jobs are
issued, are entered in this parameter:
• The LOW byte in the P4 contains the status or error code,
• The HIGH byte contains a coded recommendation concerning a reaction, or response, to
the fault message.
Error code in the LOW byte::
Code Explanation
00H No fault, correct call-up
01H The P3 parameter JBA (job bit array) is zero
02H The specified data module does not exist
03H The specified data area is too short
04H The specified byte offset is invalid
06H Wrong SFL, unsuitable ZS version
07H The R500 has not been entered in the SC table
08H R500 has wrong block address
PLC response in the HIGH byte::
Code Explanation
00H No fault, correct call-up
01H Repeat call-up of the R5REQ
02H Modify PLC program
03H Modify protocol parameters
04H The program cycle must be rerun on the R5INIT function module
05H The program cycle must be rerun on the R5REQ function module
06H The program cycle must be rerun on the R5CON function module
07H Reload the protocol
If the R5REQ detects additional fault messages on job start-up, it writes
them into the first word of the associated job block.
Parameter Attr. Description
P5 W Result bit array RBA
This parameter indicates to the user whether any faults have been identi-
fied when the jobs were issued. A job is assigned to each result bit. The
assignment corresponds to the P3 for the input parameter. A set result bit
indicates that the job which is addressed with the same bit number in P3
could not be issued. In addition, a detailed error code is output in the first
word of the associated job block, thereby completing the result bit array.
