The Modbus Block History protocol module can communicate with Modbus Block History devices using their native Modbus protocol. Devices and emulators that use the Modbus Block History protocol are also supported. 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.
The Modbus Block History protocol module supports reading and writing to all valid Modbus registers and retrieving historical data from Modbus Block History compatible Remote Terminal Units (RTUs).
