Expansion Interface Modules

The expansion interface modules are available as an expander that is added in between expansion modules to expand the number of
connected modules and as remote modules (remote master and remote slave) that are daisy chained by Ethernet cables and allow
expansion modules to be positioned away from the CPU module. Remote master/slave modules can be connected only to the Plus
CPU module.
Expansion Interface Module (Expander)
The number of expansion modules that can be connected to the CPU module (basic expansion side) is seven modules, but
additional eight expansion modules (expansion interface side, maximum 256 I/O points) can be connected by installing the
expansion interface module (expander).
CPU Module
Notes:
Only one expansion interface module (expander) can be connected to one CPU module.

When using the expansion interface module (expander) together with expansion interface modules (remote master/slave) on the Plus CPU

module, one expansion interface module (expander) can be connected per remote slave that is daisy chained to the remote master. For
details, see "Expansion Interface Modules (Remote Master/Slave)" on page 2-113.
 The maximum number of modules that can be connected depends on the modules. For detailed restrictions when using the expansion
interface module and connection examples, see "Connection Restrictions When Expanding the PLC" on page 3-34.
