Hello,
Please note that the DMC31011 has a different communications feature set than the RIO products.

Please ensure you have the newest DMC-31010 firmware. Modbus support for array access was added at 1.2a, circa July.

If you do have up-to-date firmware, the next step would be to check TC1. Do you get an error after the IH command?
