Replacing Input/Output Modules in Dual-Redundant Connection
I/O modules in dual-redundant connection must be connected to consecutive slots beginning
from an odd number.
l
Removal and Installation Procedure
1. Check the LED displays of the pair of I/O modules in dual-redundant connection to see
that the STATUS and DX LEDs are lit for both modules and ACT is lit for only one of
them.
2. Remove the four screws at the upper and lower parts of the terminal block.
3. Remove the terminal block while supporting it so as not to apply too much stress to the
flat cable.
4. While supporting the terminal block, remove the connector connected to the I/O module
whose ACT LED is not lit.
5. Remove the two screws of the I/O module whose ACT LED is not lit, and replace it with
an adjusted I/O module. Fix the screws of the replaced I/O module.
6. Download the setting information to the replaced I/O module. In SCS Constants Builder,
if Automatic IOM Download is set to [Enable], the IOM download will be performed auto-
matically.(*1)
7. Reinstall the flat cable connector.
