Edition 10/2018 SIPLACE CAN Bus

Independent of the machine type, each machine has one CAN Bus for each placement area.

This CAN Bus can be disconnect at a adequate point and the CAN switch will be connect in se-

ries. Therefore two independet CAN Bus systems are established. The structur of the CAN Bus

are described in chapter 4 as flow chart and circuit diagram.

If one or more Error frames are received the LED will be red (see red dot in the picture above).

The result is, that the Error Frames comes from the subsystem 1 or 2.

The next step could be to install the CAN Switch between subsysteme 1 and 2. Additionally you

have to check the CAN Bus-cable, whether there is no short cut or other bad connection.To elimi-

nate defect CAN Bus cable you can use CAN test cable.

Note:

The new eSW (GATWAY_0011000A.bhx) on the CAN Switch is necessary to work with the SX

machine and two WPC‘s. With this eSW the initialize procedure of the CAN Switch has a delay

time of 10sec. So therefore you have to wait 10seconds after switch ON the CAN switch before

you start with your Servicework.

3.2.1 Adapter cable CAN switch

For older machine like the HS50,60, D4, HF and partly for X-series machines the adaptercable is

necessary to transfer the additional signals Power fail, CAN Reset and the 1-wire Bus, which are

integrated in the CAN Bus cable. When we cut the machine CAN Bus into two parts with the CAN

switch box the connection of this signals will be destroyed. Because the CAN switch box transfer

CAN_H and CAN_L signals only.

The adapter cable have to connected for this machine between CAN 1 and CAN 2 of the CAN

switch box. (see picture)

3.3.1 Settings on the DIP switch

To change the DIP switch settings, disconnect the CAN Switch from the power supply and open

the upper part (label) of the CAN switch by loosen the two screws.
