S5-95F S5-95F on SINEC L1
Example: The S5-95F is to be a slave station and have the slave number 2 on the SINEC L1 bus.
Subunit A is interfaced to the L1 bus.
The following conditions apply to data transfer:
• Coordination byte UVB is flag byte 10
• Data is to be transmitted over data path 1 to slave 13 and 14
• Data is to be received over data paths 1 and 2 from slaves 13 and 14
• Slave 13 is an S5-115F programmable controller with CPU 942-7UF15 and slave 14 is an
S5-95F programmable controller
• The SINEC L1 safety time is 3 seconds for all connections
• If no valid frame can be received within the safety time, the S5-95F goes to STOP
