OK. That was easy. Lightly tested beta: For Ignition v8.1: ~~v1.1.12.250081649~~ Adds three address modifiers, "MI" for Mod10 size 2, "M" for Mod10 size 3, and "ML" for Mod10 size 4. Not yet in the user manual. For the OP, the OPC Item Path would likely be `[device]1.HRML1700` 😉 FWIW: ```python Gateway/src/com/automation_pros/modbus/address/ModbusAddress.java | 8 ++++++- Gateway/src/com/automation_pros/modbus/address/ModbusNumericAddress.java | 4 ++++ Gateway/src/com/automation_pros/modbus/driver/GenericModbusDriver.java | 4 ++++ Gateway/src/com/automation_pros/modbus/handlers/Mod10Handler.java | 121 ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 4 files changed, 136 insertions(+), 1 deletion(-) ``` Edit: The beta has been replaced with a new formal release, with this data type's OPC Item Path format now documented. > [@Automation Professionals' Advanced Modbus Driver](https://forum.inductiveautomation.com/t/automation-professionals-advanced-modbus-driver/41312/78): > > Automation Professionals is pleased to announce a new production release of this module, with one more RTU bugfix and an implementation of Schneider's "Mod10" totalizer data format.
