MODBUS Fieldbus Coupler

Configuration
interface
Power jumper contacts
This buscoupler connects the WAGO-I/O-SYSTEM as a slave to the MODBUS
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.
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 eight bits, the
buscoupler automatically starts with a new byte.
