This buscoupler connects the WAGO I/O SYSTEM as a slave to the CANopen field-
bus.
The module data is transmitted using PDOs and SDOs.
The buscoupler is capable of supporting all bus modules. The buscoupler automati-
cally 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 packed into bytes.
CANopen allows the storing of the process image in the corresponding Master con-
trol (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 CANopen fieldbus to the PLC, PC or NC for
further processing, and received from the field via CANopen.
The data of the analog modules is stored in the PDOs according to the order in
which the modules are connected to the buscoupler. The bits of the digital mo-
dules are sent byte by byte and also mapped in the
PDOs. If the amount of digital
information exceeds 8 bits, the buscoupler automatically starts with a new byte.
All entries of the object dictionary can be mapped - as the user likes - in the 32 Rx
PDOs and 32 Tx PDOs.
The complete input and output process image can be transmitted using SDOs.
“Spacer modules“ can be set via software.
