S5-115F Manual
Communications Capabilities
Mailboxes A and B in the slave PLCs indicate identical mailboxes in both subunits. The master PLC,
on the other hand, has only one Send mailbox and one Receive mailbox.
Configuring
The mailbox system for the SINEC L1 LAN is configured for the slave ( Vol. 2, 1.1.2 of the manual).
For this purpose, COM 115F installs a table of Send mailboxes and a table of Receive mailboxes in
configuration DB1. Five bytes are reserved for each mailbox. You must also install coordination
bytes for the master.
Table 7-10 shows the configuring procedure of the SINEC-L1 structure tailored to the above
example:
