Bradley Smoker PLC-5 Chassis Configuration Plug, 6Switch Setting Reference, Power supply module

E-6Switch Setting Reference

ATTENTION

If you set this switch to the ON position, when a communication fault is detected, outputs connected

to this chassis remain in their last state to allow machine motion to continue. We recommend that you set switch 1 to the OFF position to de-energize outputs wired to this chassis when a fault is detected.

Also, if outputs are controlled by inputs in a different rack and a remote I/O rack fault occurs (in the inputs rack), the inputs are left in their last non-faulted state. The outputs may not be properly controlled and potential personnel and machine damage may result. If you want your inputs to be anything other than their last non-faulted state, then you need to program a fault routine.

Set this switch to ON if you plan to use I/O rack auto-configuration. The 1771-ASB series A adapter does not support 1/2-slot addressing.

1. Locate the chassis configuration plug (between the first two left-most slots of the chassis).

2. Set the I/O chassis configuration plug. The default setting is N (not using a power supply module in the chassis).

Important: You cannot power a single I/O chassis with both a power supply module and an external power supply.
