Caution!
Only certain combinations of submodules (see Table) on the I/O board are permissible. The
individual slots are also marked and assigned to the following terminals in the connection
compartment of the transmitter:
• "INPUT / OUTPUT 3" slot = terminals 22/23
• "INPUT / OUTPUT 4" slot = terminals 20/21
