MODBUS.SCALING

Description

Modbus has its own scaling algorithms. For some simple HMI's, it is desirable to use WorkBench units instead of these Modbus-specific units. The parameter MODBUS.SCALING allows users to disable Modbus scaling and enable WB (Telnet) scaling.

Setting Description
0 Modbus uses same scaling units as WorkBench (set by UNIT parameters).
1 Modbus uses the Modbus-specific scaling units (set by MODBUS parameters).

Fieldbus Information

If your drive type is listed as supported but no index, address, or instance number is listed, then this parameter is accessible through WorkBench, but not over your fieldbus type. For information on SynqNet parameters see SynqNet Supported Parameters.
