expanded with a maximum of 63 modules (I/O points: maximum 2,016 points) using expansion interface
remote modules. The expansion interface remote modules are the remote master which connects tothe expansion connector of the Plus CPU module and the remote slave which connects to expansion
modules that are positioned away from the CPU module.
The expansion interface remote master module can be connected only to the basic expansion side of
the Plus CPU module. At this time, the maximum number of expansion modules (basic expansion side)that can be connected to the remote master is five modules, but this can be increased to an additionaleight expansion modules (expansion interface side) by installing the integrated expansion interface module.
Expansion interface remote slave modules are daisy chained to the remote master using Ethernet cables.
The group of expansion modules that are connected to the expansion connectors and communication
connectors of the Plus CPU module and expansion interface remote slave modules are called as nodes.
As show by the figure below,the first node that includes the Plus CPU module is called node 0, and thenodes containing remote slaves are called node 1, node 2, and up to node 10 in order from those closest
to node 0. The maximum number of nodes is 11, from node 0 to node 10.
The maximum number of expansion modules (basic expansion side) that can be connected to a remoteslave is seven modules, but this can be increased to an additional eight expansion modules (expansion
interface side) by installing the integrated expansion interface module.

Safety Precautions

FC6A Series
Plus CPU module

Special expertise is required to use the MICROSmart.
● Read this instruction sheet and the user's manual to make sure of correct operation before starting
installation, wiring, operation, maintenance, and inspection of the MICROSmart.
Keep this instruction sheet where it can be accessed by the end user.
● All MICROSmart modules are manufactured under IDEC's rigorous quality control system, but users
must add backup or failsafe provisions to control systems use the MICROSmart in applications where
heavy damage or personal injury may be caused if the MICROSmart should fail.
● Install the MICROSmart according to the instructions described in this instruction sheet and the user's
manual. Improper installation will result in falling, failure, or malfunction of the MICROSmart.
● Make sure that the operating conditions are as described in the user’s manual. If you are uncertain
about the specifications, contact IDEC before using the MICROSmart.
● In this instruction sheet, safety precautions are categorized in order of importance from Warning andCaution:Warning notices are used to emphasize that improper operation may cause severe personal injury or death.

● The environment rating for using the MICROSmart is “Pollution degree 2.”(6) Expansion Connector 2(8) Ground Terminal● Prevent metal fragments and pieces of wire from dropping inside the MICROSmart housing.

Ingress of such fragments and chips may cause fire hazard, damage, or malfunction.

● Use wires of a proper size to meet voltage and current requirements. Tighten terminal screws to theproper tightening torque of 0.49 N-m.
● Use an IEC60127-approved fuse on the power line and output circuit to meet voltage and current
requirements.(Recommended fuse: Littelfuse 5×20mm slow-blow type 218000 series/Type T)
This is required when exporting equipment containing MICROSmart to Europe.
● Use an EU-approved circuit breaker. This is required when exporting equipment containing
MICROSmart to Europe.
● If relays or transistors in the MICROSmart output modules should fail, outputs may remain on or off.
For output signals which may cause heavy accidents, provide a monitor circuit outside of the
MICROSmart.
● Do not disassemble, repair, or modify MICROSmart modules.

If there is an interruption of the power supply (power off) to an expansion interface remote slave
module during operation, the outputs of all expansion modules (both basic expansion and expansion
interface sides) connected to the node of the expansion interface remote slave module will turn off
while the power is interrupted.
When the power is restored, the expansion interface remote slave module that experienced the powerinterruption will be reset to its initial state, and the outputs of the expansion modules will not recoverautomatically.
Turn on special internal relay (M8320) on the Plus CPU module to reconfigure the settings of the
expansion interface remote slave module and recover the outputs of the expansion modules.
During the power interruption, I/O refresh will also be stopped for the expansion modules connected tonodes located downstream from the node of the expansion interface remote slave module that has
experienced the power interruption.
The outputs of the expansion modules (both the basic expansion side and the expansion interfaceside) for which I/O refresh has been stopped will be automatically turned off after 10 seconds.
However, when the power supply to the expansion interface remote slave module of the upstream
node that experienced the power interruption is restored, I/O refresh for the expansion modules ofdownstream nodes will be automatically restarted, and the outputs of the expansion modules will be
automatically restored.
If there is an interruption of the power supply (power off) to an integrated expansion interface module
during operation, the outputs of all expansion modules of the node that are connected to this module
will turn off while the power is interrupted.
When the power recovers from the interruption, the expansion modules (both the basic expansion sideand the expansion interface side) are restored to their original statuses.
