Define signal groups
When an error is recognized, all signal groups (0 to 31)
respond with PLC STOP
You can assign each signal group its own error response.
Permissible range of values
Signal group z:
z = 0, 1, ..., 31, Z
Response in the case of error v:
v = S, P, L, O, A
S = PLC STOP
P = Passivation
L = Read in previous value
O = ORing of subunit signals
A = ANDing of subunit signals
Slots of the external I/O modules
All slots for external I/O modules are reserved for single-
channel (non-failsafe) modules.
Slot is occupied with failsafe module.
Permissible range of values
Slot no. in subunit A:
x = 0, 2, ... 30
Redundantly operated module belongs to signal group s
s = 0, 1, ... 31
I/O type t
t = DI, DQ
Note:
The slot no. (x + 1) in subunit B must not be parameterized.
