Communications interfaces

The MM300 has three communications interfaces:

•RS485

•10/100Base-T Ethernet

•Fieldbus

Setpoint changes related to DeviceNet, Profibus, and Ethernet, require a power cycle to be activated.

NOTE

External power must be present on the Fieldbus port at power-up, in order to correctly initialize.
