Wago 750-303 WAGO-I/O-SYSTEM 750 Fieldbus Coupler
Fieldbus Coupler PROFIBUS DP, Baud rate: 9,6 kbaud-12 Mbaud, Buscoupler connection: 1x D-Sub 9 socket, no. of I/O modules: 64, input process image max.: 128 Byte, output process image max.: 128 Byte, no. of couplers connected to Master: 96 with repeater
This buscoupler connects the WAGO-I/O-SYSTEM as a slave to the PROFIBUS fieldbus.
The buscoupler automatically configures, creating a local process image which may include analog, digital or specialty modules. Analog and specialty module data is sent via words and/or bytes, digital data is sent bit by bit.
PROFIBUS stores the process image in the corresponding Master control (PLC, PC or NC).
The local process image is divided into two data zones containing the data received and the data to be sent. The process data can be sent via the PROFIBUS fieldbus to the PLC, PC or NC for further processing, and received from the field via PROFIBUS.
The data of the analog modules is stored in the process image which is created automatically according to the order in which the modules are connected to the buscoupler. The bits of the digital modules are sent byte by byte and added to the analog data. If the amount of digital information exceeds 8 bits, the buscoupler automatically starts with a new byte.
When implementing new installations, please consider 750-333 PROFIBUS DP fieldbus coupler with extended functions. Notice: GSD files required!
typ. 1 ms (10 couplers, 32 digital I/Os per coupler at 12 Mbaud) max. 3.3 ms
