750-628
The coupler module for the internal data bus extension module 750-628 replaces
the fieldbus coupler/controller at an I/O terminal block. It is also the mating piece
for the end module 750-627. Plug the connecting cable into the top RJ-45 socket to
establish the logical link to the fieldbus coupler/controller via end module 750-627.
The extension is completely transparent for the fieldbus coupler/controller. All of the
functions of the I/O module system are retained without any changes. A further
extension to the system is provided by the bottom RJ-45 socket. This enables the
entire system to be extended by 10 stages.
The supply voltage for the field side and the internal electronics can be input
separately. Both levels are electrically isolated from each other. Two diagnostic LEDs
give information about the supply voltage for both the internal and field side. Two
LEDs in the input socket indicate fault-free communication with the bus coupler. The
extension module can be used as the last coupler module in the system (switch on
matching resistor) or as a bridge between two I/O module assemblies.
Installation note Attention:
To ensure safe, reliable operating states when using the internal data bus extension
750-627/-628 these states must be registered prior to startup with the following
couplers or PLCs (refer to manual for supported couplers/PLCs). You must use the
"WAGO Extension Setting" software for this (download: www.wago.com).
Please note that only one terminating resistor may be activated in the whole system.
Please complete the manufacturing number matrix on the right-hand side of the
couplers when updating the firmware and internal operating parameters.
