| MODULE BUS EXTENSION, COUPLER MODULE |
The internal data bus extension coupler
module 750-628 replaces the fieldbus coupler/ controller on an I/O module
assembly. It is the counterpart to the end extension module
750-627. The connecting
cable is plugged into the RJ 45 input socket, providing the logical connection
to the fieldus coupler/ controller via the internal data bus extension end
module 750-627. The
extension does not interfere with the fieldbus coupler/ controller, all bus
module system functions remain unchanged. The RJ 45 output socket allows
further extension of the system (max. 10 stations).
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 RJ 45 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 Notes:
In order to guarantee safe operating
conditions when using the internal data bus extension modules 750-627/-628, the
buscouplers must have the internal parameters set accordingly. Please order the
WAGO extension setting tool 759-314 and use it to inform the buscouplers/
controllers 750-304, 750-306, 750-310, 750-319, 750-324, 750-333, 750-337,
750-339, 750-342, 750-804, 750-806, 750-19, 750-833, 750-837, 750-841, 750-842,
including all variations, of the new operating parameters. Please complete the
manufacturing number matrix on the right-hand side of the couplers when
updating the firmware and internal operating parameters. On the left-hand side
of the buscouplers, please use the markers (enclosed in 759-314) to identify
the modules that have been activated / deactivated. |
