Relationship between Built-in Inputs and Terminal Block Arrangement
Terminal Block Arrangement
Setting Input Functions in
the PLC Setup
Functions for the normal input terminals in the built-in inputs can be individu-
ally allocated by making selections in the PLC Setup.
Note High-speed counter terminals are line -river inputs, so they cannot be used as
normal inputs.
