The number of connection resources that a CPU or a communication module supports is
specified in the device manuals in the Technical Specifications.
Example
You have configured a CPU 1516-3 PN/DP with a CM 1542-1 communication module and a
CP 1542-5 communication processor.
● Maximum connection resources of the station: 256
● Available connection resources:
– CPU 1516-3 PN/DP: 128
– CM 1542-1: 64
– CP 1542-5: 16
– Total: 208
The setup provides 208 connection resources. By adding further communication modules,
the station can support a maximum of 48 additional connection resources.
