Fieldbus Coupler 750-306
3.1.1 Description
The fieldbus Coupler 750-306 displays the peripheral data of all I/O modules in the WAGO-I/O-SYSTEM 750 on DeviceNet Feldbus. The data is transmitted with objects.
The bus Coupler determines the physical structure of the node and creates a process image from this with all inputs and outputs. This could involve a mixed arrangement of analog (word by word data exchange) and digital (byte by byte data exchange) modules.
The local process image is subdivided into an input and output data area. The process data can be read in via the DeviceNet bus and further processed in a control system. The process output data is sent via the DeviceNet bus.
The data of the analog modules are mapped into the automatical created process image according to the order of their position downstream of the bus Coupler. The bits of the digital modules are compiled to form bytes and also mapped into the process image attached to the data of the analog modules. Should the number of digital I/Os exceed 8 bits, the Coupler automatically starts another byte.
The fieldbus Coupler supports the DeviceNet function Bit-Strobe, whereby the function is insofar restricted, that only the status byte will be delivered.
