Wiring the redundant function modules
This section describes how to wire the redundant function modules.
Wiring method
Connect the tracking cables from the OUT connector of a redundant function module to the IN connector of the other
redundant function module.
For the specifications of the tracking cables connected to redundant function modules, refer to the following.
MELSEC iQ-R CPU Module User's Manual (Startup)
Connecting/disconnecting tracking cables
■
Connection procedure
1.
Pay attention to the direction of a tracking cable connector and insert the cable to a redundant function module until it
clicks. A redundant function module has one IN connector and one OUT connector. Connect the IN connector of the
system A and the OUT connector of the system B with a tracking cable and connect the OUT connector of the system A
and the IN connector of the system B.
2.
Pull each cable lightly and check that it has been connected securely.
■
Disconnection procedure
1.
Disconnect the tracking cables while pressing the connector hook.
Precautions
• There are restrictions on the cable bending radius. For details, refer to the specifications of the tracking cables used.
• Place the cables in a duct or clamp them. If not, a dangling cable may swing or inadvertently be pulled, resulting in damage
to the module or cables or malfunction due to poor contact.
• When connecting tracking cables, pay attention not to touch optical fiber cores of the connectors on the cables and module
sides and prevent dirt and dust from adhering to them. If oil on hands, dirt, and dust adhere to the optical fiber cores, the
transmission loss increases and tracking may not work properly.
• Hold the connector of the tracking cables to connect or disconnect the cable. Pulling the cable connected to the module
may result in malfunction or damage to the module or cable or malfunction due to poor contact.
