Skov CAN bus module Technical User Guide

  • Hello! I've reviewed the Technical User Guide for the SKOV CAN Bus Module. This document provides detailed information on how to mount, electrically connect, and troubleshoot the module. It includes various connection options and covers jumper settings needed for CAN bus communication. I'm ready to answer any of your questions.
  • What is the maximum length of the CAN bus cable that can be connected to the CAN Bus Module?
    What are the types of CAN bus cables supported?
    What does the EXTTERM jumper do?

4.1 Electrical connection
Installation, servicing and troubleshooting of all electrical equipment must be carried out by quali-
fied personnel in compliance with the applicable national and international standard EN 60204-1
and any other EU standards that are applicable in Europe.
The installation of a power supply isolator is required for each motor and power supply to facilitate
voltage-free work on the electrical equipment. The power supply isolator is not included.

4.1.4 Setting CAN termination jumpers
The modules are controlled via CAN bus communication. It is important that the CAN termination jumpers are
set correctly in order to achieve secure communication between the modules. The jumper must be ON on the
module where communication ends.

5 Troubleshooting guide
Error
No light in RXD (green) and TXD
(red) LED on CAN bus module.
Check for 24 V DC socket J40 or J41 on the CAN bus module, see the
section Connections on CAN bus module [}9].
TXD (red) LED shines. No light in
RXD (green) and on CAN bus mod-
ule.
No data is received from the CAN bus.
Check that the CAN bus cable is connected correctly and that power is
being supplied to the production controller.
External box does not appear as
connected in the climate/production
controller.
Check that the correct addresses are selected on the I/O modules.
Check resistance between CAN-Hi and CAN-Lo, the resistance must be
approximately 60 ohms.
If the resistance is > 100 ohms, a termination is missing.
If the resistance is < 45 ohms, there are too many terminations.
All units connected to the CAN bus must be measured without power
supply.
Check the jumper settings, see the section Setting CAN termination
jumpers [}11].
