CAN communication (X101/102)
4.3.2. CAN communication (X101/102)
TopCon power supplies that are operated in a multi-unit system require
system-internal communication via the related interfaces X101/X102.
The tasks of the individual TopCon power supplies and their peripheral
modules, e.g. RCUs and series controllers are controlled via the CAN
communication. At the same time the CAN communication is used for
communication between the system master and the slaves assigned.
The interfaces X101 and X102 have the following tasks:
CAN interface, for the communication
Interlock connection
The related interface must always be “terminated”, i.e. fitted with the related
dummy plugs or a bus connection.

labelling.
Interlock connector, D-Sub, 25-pin (dummy plug)
Label: “X105; Interlock CTR 4”
Is connected on the rear side of all devices to interface X105.
Interlock or CAN-Term, D-Sub, 9-pin (dummy plug)
Label: “X101; CAN TERM; Interlock CTR 4“
Is connected to interface X101 on the rear side of the device at the start of the
CAN multi-unit system.
CAN-Term, D-Sub, 9-pin (dummy plug)
Label: “X101; CAN TERM;”
Is connected to interface X102 on the rear side of the device at the end of the
CAN multi-unit system.
Table 17 Dummy plugs and their labelling.
Only one CAN-Term is allowed to be connected to a single device.
Independent of whether X101 or X102 is used.
