PROFIBUS DP/FMS
Fieldbus Coupler
This buscoupler allows connection of the WAGO I/O SYSTEM as a slave to the PROFIBUS fieldbus.
The buscoupler is capable of supporting all I/O modules. The buscoupler automatically configures, creating a local pro-
cess 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 allows the storing of 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 with PROFIBUS DP, please consider fieldbus coupler 750-333 with
extended functions (page 1.020).
