Page 22: Data Structure
Implemented protocols in UNIGATE® MB Deutschmann Automation GmbH & Co. KG The user can choose whether the fieldbus requests are forwarded to the Modbus in case of a change (On Change) or on request (On Trigger). In "Change" mode, detection of a change is based on the fact that the fieldbus data is compared with that of the last transmission, and a request is issued by the Modbus only in the case of a change. -
Page 23: Data Structure
Deutschmann Automation GmbH & Co. KG Implemented protocols in UNIGATE® MB Since the Modbus operates with a variable data format - dependent on the required function and data length - but since the fieldbus requires a fixed data length, this must be preset by means of a selection in the device description file. -
