Not all registers are active on all units. Write a simple script to scan registers 0 to 500 and log any non-zero, non-65535 values. Compare these to the unit's local display. This is located on the terminal board of
To establish communication, you must configure the following settings within the controller's user menu: Baud Rate: Typically 9600 or 19200 baud Range from 001 to 200 (Default is often 11) Supervision Enable: Compare these to the unit's local display
