Modular Block System: Emergency Stop Circuits 6-13
- E 002: Parameter error
SSNR assigned more than once OR
DW1015 in DB015 was not incremented
Global parameters used in administration data block DB015
Global parameters may be set with SB070 in OB120.
• DW1001: Number of cycles in the contact synchronisation time between
the 2 N/C contacts on the E-STOP button
• DW1015: Counter for monitoring the SSNR
INFORMATION
On some blocks (e.g. E-STOP) the input parameter
SSNR is monitored.
These blocks must be run through as part of each PSS-cycle. The
following commands should therefore be entered once only at the end of
OB101:
A DB015
I DW1015
Effect:
The counter for monitoring the
SSNR in DB015/DW1015 (global
parameters) will be incremented.
Blocks required
• DB015: Administration data block
DB015 must consist of its total length of 1024 data words.
DB015 must have READ/WRITE access.
• SB070 Initialisation of global parameters in DB015
• SB255: To call up the operating system
