For larger systems, additional serial channels must be added. Commercially available repeaters can also be used to add more than 32 relays on a single channel.

  • Page 34: Protection Modules

    CAUTION: that the common terminals of each RS485 port are tied together and grounded only once, at the master or at the MM300. Failure to do so may result in intermittent or failed communications. The source computer/PLC/SCADA system should have similar transient protection devices installed, either internally or externally.

This is illustrated in the following procedure: Establish communications with the MM300 relay. Select the Online > Device Setup menu item and record the Firmware Revision from the Device Setup window.

Once your physical connections are complete and you have determined which COM PORT you will be using, start your MM300/MM200 EnerVista Setup Program. Save the setpoints to a file as shown in Downloading and Saving Setpoints Files.

While the file is being loaded into the MM300 a status box appears showing how much of the new firmware file has been transferred and the upgrade status. The entire transfer process takes approximately 10 minutes.
