Discrepancy time for external DI
Discrepancy time for all redundant external DIs: one OB1 cycle
You can assign individual bits or bytes a different discrepancy
time
Byte address x:
x = 0, 2, 4, ..., 30, X
Bit no. y:
y = 0, 1, ..., 7, Y
Discrepancy time t:
t = 1 to 255L1
t = 1 to 255L13
SINEC L1 basic parameter assignment
SINEC L1 programmer bus not used
SINEC L1 data bus not used
If you use the SINEC L1 programmer bus and/or the SINEC
L1 data bus, then enter the number of the node after the
Node no. at the programmer bus
Node no. at the data bus
Non-failsafe SINEC L1 at subunit A
Coordination bytes, send and receive mailboxes are not
assigned default parameters.
If you use a SINEC L1 data bus, you must define the location
of the coordination bytes and the send and receive mailboxes.
Permissible range of values
No. of the flag byte/data word
Block no. of DB
