Expansion Interface Module
Slim type CPU modules can normally connect a maximum of seven I/O modules. Using the expansion interface module
makes it possible to connect additional eight I/O modules to expand another 256 I/O points. The maximum number of I/
O points is 512, including the I/Os in the CPU module.
Expansion interface modules are available in two mounting styles: for integrated mounting and separate mounting.
For the integrated mounting, expansion interface module FC5A-EXM2 is mounted next to the seventh I/O module and
more I/O modules are mounted next to the expansion interface module.
For the separate mounting, expansion interface master module FC5A-EXM1M and expansion interface slave module
FC5A-EXM1S are used. The expansion interface master module is mounted at the end of I/O modules, the expansion
interface slave module is used at the beginning of the other I/O modules, and the master and slave modules are con-
nected with expansion interface cable FC5A-KX1C.
