Principle of operation of option handling

Principle
With option handling, the configuration of slots 2 to 63 of the ET 200S is checked. If the
check is enabled for a slot, the RESERVE module (option) or a configured electronic module
can occupy this slot without a diagnostic being signaled. If the check is disabled, only a
configured electronic module can be located in this slot. Any other module will trigger a
diagnosis. You can also control the configuration of slots 2 to 63 and monitor the
configuration of slots 1 to 63 using the control and feedback interface in the process input
image (PII) and process output image (PIQ).
