ules (1 bit per I/O module)
0x1028–0x102F ro Byte Module status (2 bits per I/O module) 00 =
module I/O 01 = module error 10 = incorrect

0x1030 ro Word MODBUS DATA EXCHANGE watchdog, current
time (x*10 ms) 0 = watchdog has expired
0xFFFF = watchdog deactivated
Time still remaining for monitoring the exchange of
process data
0x1120 rw Word MODBUS DATA EXCHANGE watchdog,
predened time (x*10 ms) default = 0 ms -> no
watchdog active
Time for monitoring the exchange of process data
0x1121 rw Word MODBUS DATA EXCHANGE watchdog reset
register Bit0 = 1 – watchdog reset at predened
time Bit8 = 1 – restart after expired watchdog
Bit 0: reset watchdog while it is running = retrigger
Bit 8: restart of expired watchdog
