Page 18: Mode Of Operation Of The System
Communication can be split into seven layers, Layer 1 to Layer 7, in accordance with the ISO/OSI model. The Deutschmann Automation Gateways convert Layers 1 and 2 of the customized bus system (RS485 / RS232 / RS422) to the corresponding Fieldbus system. Layers 3 to 6 are blank, and Layer 7 is converted in accordance with chapter 7.3. -

Page 23: Data Structure
Deutschmann Automation GmbH & Co. KG Implemented protocols in UNIGATE® MB 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 24: Data Structure
Implemented protocols in UNIGATE® MB Deutschmann Automation GmbH & Co. KG 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. -
Page 25: The Trigger Byte
Deutschmann Automation GmbH & Co. KG Implemented protocols in UNIGATE® MB The trigger byte Since the data is always transferred cyclically on PROFIBUS, the gateway must detect when the user wishes to send new data via the serial interface. This is normally done by the gateway com- paring the data to be transferred via the PROFIBUS with the old data stored internally - data exchange on change (data exchange ->... -
