Safety Time in the
S5-115F
Step
1
Verify the conditions for the SINEC L1
safety time for receiving, using the formula
on Page 5-14.
2
Subtract the local cycle time for receiving of
the S5-115F from the specified SINEC L1
safety time for receiving.
3
Round this time down to the next multiple of
10 ms.
4
Enter this value as SINEC L1 safety time for
receiving in COM 115F.
Communications Processor CP 541
EWA 4NEB 812 6188-02
Proceed as follows to determine the SINEC L1 safety time for an S5-115F.
Action
CP 541 with S5-95F/S5-1 15F
Meaning
The calculated value must be less than the
SINEC L1 safety time for receiving.
The local cycle time for receiving must be
subtracted from the SINEC L1 safety time,
because the received messages will be inter-
mediately stored in the CP 541.
You can only specify the safety time in
COM 115F in multiples of 10 ms.
For reception over two or more data paths,
you must set the highest value.
