3.1 Option handling with RESERVE modules
3.1.1 Principle of operation of option handling with RESERVE modules
Principle
With option handling with RESERVE modules, the configuration of ET 200S Slots 2 to 63 is
checked. If a slot is enabled for option handling, the RESERVE module (option) can occupy
this slot instead of the configured electronic module without triggering a diagnostic interrupt.
If the slot is disabled, only the configured electronic module can occupy 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).
