Can Interface - HBM MP60 Operating Manual

PME-MP60/MP07

4.5 CAN interface

The CAN-bus is connected via terminal plug 1. A maximum of 32 CAN users
can be connected in one bus segment.
The CAN-bus needs a terminating resistance of 120 Ω in the first and last bus
users. A terminating impedance is integrated into the MP60 module which is
activated by the S14 DIP switches (see page 14).

NOTE
If the first or last device in a bus circuit is not a PME module, then a
120 W resistance must be switched on at these pieces of equipment.
