6-8 Modular Block System: Emergency Stop Circuits
Standard Function Blocks
Global parameters used in administration data block DB 015
Global parameters may be set with SB070 in OB120.
• 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 DB 015
• SB255: To call up the operating system
SB060
