MVI56-MCM with double CPU

[Olivera 0]

Hello: I would like to know how can I configure the MVI56-MCM module to work with CPU double in the same chasis. I want that the two CPUs reads the MODBUS values. Thanks

The MVI56-MCM can't be owned by more than one controller, so you cannot natively have two controllers reading its database. However, it is very straightforward to copy the module's database registers into a Produced Tag in the owner controller, and have that tag (it will be an array of INT values, probably) be Consumed by the other controller.

Eddie has definitely given you the best solution but not the only. YOu can with SSV/GSV commands change the owner of the module, but this is far from efficient and bug free.

you can do produce/consume tags between the two processors
