11.3.8 Safety Data Monitoring
This function is works only in YRC1000.
By using the signals for the safety data monitoring (CSCFG01, CSCFG02,
CSCFG03, CSCFG04, SICFGTRG), the safety data (the safety-related
parameter, the machine safety data file, and the functional safety data file)
can be monitored to detect a change.
Monitoring is performed by comparing the CRC of the safety data, and if
changed, that can be notified by the safety output.
When GSIN01 is the stored CRC updating trigger, the example of the
monitoring results output to MS-OUT01 - 04 is shown below.
1. Editing the safety logic circuit
– Correspond GSIN01 to the updating trigger SICFGTRG, and
MSOUT01 - 04 to CSCFG01 - 04.
2. Write the Safety Logic Circuit
– After editing, select {WRITE}.
– When the transfer is done correctly, the confirmation dialog appears.
Then select {YES}.
Since the CRC for the safety data monitoring are stored by
detecting falling edge of SICFGTRG(CRC updating trigger),
the monitoring results are turned OFF (
〇: abnormal
monitoring) until the stored CRC is updated by this signal.
