S5-115F Manual Communications Capabilities
Example for one-channel SINEC L1 LAN:
In this SINEC L1 LAN programming example, four S5-115Fs are:
• connected together in a safety-related configuration with 115F-14 message mode
• connected to the master S5-115U in a nonsafety-related configuration
The following transfers are implemented:
Partner Connections
Master 0
Slave 1
Slave 2
Slave 3
Slave 4
When an error occurs, Slave 1 sends the body of the error DB (with the error message code) to the
master in addition to the normal messages. The master only sends to Slave 1, which exchanges
data in both directions with the other three slaves.
The following figure shows the mailbox structure for a one-channel SINEC L1 LAN.
The uppercase letters in the figure refer to the subunits. In the case of Send mailboxes, the digits
indicate the destination PLC. In the case of Receive mailboxes, the digits indicate the source PLC.
”0” indicates the master and the digits 1 to 4 indicate the slaves.
