Multiple Modules of the Same Type

The eManager/eCore can handle multiple modules of the same type at the same time. For example, we can build an eManager with two 7AI+2PR and three 10DI modules to manage 14 AI (analog inputs), 4 PR (power relays) and 30 DI (digital inputs).

Different physical modules of the same type attached to an eManager/eCore are distinguished at a software level by a module number or variant number.

Enumeration rule

For modules of the same type, the closest variant to the main module (the one with the Ethernet connector) is assigned with the module number or variant number 1. The variant number 2 is assigned to the second closest and so on.

Modules with no repeated counterpart are assigned with the variant number 1.
