1.2 General

The CAN Test Box is a tool for service technicians to test basic CAN bus functions at SIPLACE

machines. This CAN Test Box can be used on machines implementing a CAN bus with a baud

rate of 500 kBit or 1 MBit. Although the CAN Test Box can also be used for the slower CAN bus

(125kBit) on HS50/60 machines, the Error Frame Counter will not function in this case.

The following functions can be checked:

– Terminating resistors

– Recessive voltage levels

– Dominant voltage levels

– Power fail voltage level, CAN reset

– Error frames

1.3 CAN Bus Signal Assignment

Fig. 1.3 - 1 Signal assignment at the different connectors

– CAN_INT – not in use (+5V)

– Power Fail – triggers recording of operating data at the placement head (+5V)

– CAN RESET – not in use (+5V) (HS50/60 use the signal for the Tape cutter and component

table)

– CAN HIGH - 2,5 +/– 0,3 V recessive level (machine in idle mode)

– CAN LOW - 2,5 +/– 0,3 V recessive level (machine in idle mode)

– CAN GND - Can bus ground

– Vcc 24V - for nozzle changers - no longer available after the above mentioned conversions

– One wire - only applies to HF series, in the machine CAN bus cable

1.4 CAN Test Box Connections

Fig. 1.4 - 1 CAN Test Box connections

(1) Switch for setting the baud rate to 1 MBit or 500 kBit

(2) Switch for enabling an additional 120 Ohm resistance.

(3) Power LED to show the power supply state (green = power on)

– 5V voltage supply from the axis card or external power pack

– CAN BUS PC connection PC (Sub D female connector). Only the CAN High, CAN Low and

GND signals are run to the PC (Kvaser card), preventing PC-card corruption.

– CAN BUS_MA connection to the machine, COM assembly (Sub D female connector)

– CAN BUS_MA connection to the machine, COM assembly (Sub D male connector)

– Banana jack for CAN High measurement of recessive CAN bus level against CAN GND

– Banana jack for CAN Low measurement of recessive CAN bus level against CAN GND

– Banana jack for CAN GND ground CAN bus

– BNC socket for CAN High

– BNC socket for CAN Low

– BNC socket RxD shows the combination of CAN High and CAN Low signals to a TTL level, as

read by the CAN telegram processor.

– BNC socket for Error Counter from display

– BNC socket for power fail to check of the level in the line (4,0 - 5,0 V).

– BNC socket for CAN reset to check of the level in the line (4,0 - 5,0 V).
