BUEP03E Protocol 8-33
8.8 Checkback Signals and Fault Messages
The jobs can be started or terminated with the R5REQ function module.
The R5CON function module monitors the issued jobs. If the job has been
terminated or terminated, BÜP03E enters the information into the job ta-
ble on the ZS module via the processed jobs. R5CON reads this informa-
tion which the user receives in his output parameters (P3, P4).
The R5CON function module has two input and three output parameters
(see also the specification for the R5CON function module). These para-
meters are defined as follows.
P0 (word): CXN and channel number
P1 (word): Job number
P2 (word): Job number
P3 (word): Status
P4 (word): Fault message
P2 (job number) indicates to which job the words, P3 (status) and P4
(fault message), have been designated.
The BÜP03E protocol generates fault information which is divided into
three areas:
• PLC response (byte)
• Error class (byte)
• Error code (byte)
If commands are interlinked, additional information is required to define
the command in which the fault or job abort has occurred. This informati-
on, known as "Interlinking depth", is provided in a marker byte which is in-
dicated in the Receive Mode command.
The existing error classes and those jointly used by BÜP03E are
- 30H System bus
- 31H Operating system
The error class
- 40H BÜP03E protocol
is defined for the BÜP03E itself.
