Process alarm
A process alarm causes a call of the OB 40. Within the OB 40 you have the possibility of
determining the logic basic address of the module that has triggered the process alarm via
the local word 6. Further information on the triggering event can be found in the "Local
double word 8".
Local double word 8 of OB 40:
Local byte Bit 7 ... 0
8 Bit 0: Limit value exceeded channel 1
Bit 1: Limit value exceeded channel 2
Bit 2: Limit value exceeded channel 3
Bit 3: Limit value exceeded channel 4
Bit 7 ... 4: 0 (fixed)
9 Bit 0: Limit value not reached channel 1
Bit 1: Limit value not reached channel 2
Bit 2: Limit value not reached, channel 3
Bit 3: Limit value not reached, channel 4
Bit 7 ... 4: 0 (fixed)
10 ... 11 Ticker value at the time of the alarm
After mains connection, a timer (
ms ticker) is started which after 65535 ms starts with 0 again.
