DOK-VISMOT-VM*-09VRS**-WA02-EN-P
542 PLC Cyclic Mapping Timeout
Cause:
The Fieldbus Mapper continually scans the system for sufficient
resources to process the PLC cyclic data mapping list C-0-2600. If 10 out
of 10 attempts of the mapping list update are missed, the system is
considered to have insufficient resources. This error message is issued
when control parameter C-0-2635 (Fieldbus/PLC Error Reaction) is set to
shutdown (0x0000) and C-0-2613 (Fieldbus/PLC Cyclic Channel: Timeout
Counter) increments by 1.
Motion to all axes will stop based on the selected error reaction at each
drive.

Fig. 3-16: Fieldbus Slave Shutdown Error
Remedy:
The control’s mapping list is scanned every 4 ms for GPP09 and fixed at
8 ms for GPP08. If this error occurs, contact Bosch Rexroth Service for
assistance.
543 PLC Runtime Error
Cause:
This error is issued when trying to download a PLC program while the
control is in phase 4.
Remedy:
Switch the control to phase 2 before downloading a PLC program.
544 RECO I/O Failure, see ext. diag.
Cause:
The RECO I/O module has reported a fatal error. VisualMotion
acknowledges fatal errors if bits 6 and 7 in the control parameter
C-0-0010 (System Options) are set as follows:
Bit 6 Bit 7 Reaction
x 1 Fatal Error (default)
Table 3-14: RECO I/O Error Reaction Bit Settings (C-0-0010)
If Bit 7 is both set to 1, VisualMotion will detect a fatal error.
