The Modbus OMNI device object in AutoSol Communication Manager® (ACM) can communicate with OMNI devices or any device that supports the Modbus OMNI protocol. The Modbus Omni device object provides support for a number of documented Modbus variations, as well as the ability to build customized register sets and functions codes. This user guide only covers specific information unique to Modbus OMNI devices.
Supported Devices
The Modbus OMNI protocol module can communicate with OMNI devices using the native Omni Modbus protocol. Devices and emulators that use the OMNI Modbus protocol are also supported. However, keep in mind that some emulators do not always support or emulate the full function code set in the OMNI. Custom register sets and function codes can be created to communicate with any Modbus-type device that uses the Modbus protocol frame format with non-standard function codes, registers, and data types.
Supported Features
The Modbus OMNI protocol module supports reading and writing to all valid Modbus registers and retrieving historical data (including data logs) from OMNI compatible RTUs.
