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 PROFI-
BUS 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 750-333 Fieldbus Coupler with extended functions (page 104).
