When should I use an MVI56E-MNETCR?

This multi-client Modbus TCP In-Chassis module has been designed for ControlLogix applications where the MVI56E-MNETCR is in a remote rack from the ControlLogix processor, and is linked to the processor chassis via ControlNet. This firmware has been designed with a smaller block transfer size to the ControlLogix processor, which makes it easier to schedule the ControlNet network.It is recommended to use the MVI56E-MNETC module for other Modbus TCP applications.
