CAN Bus Terminator
The A3 assembly ensures that the CAN bus also functions with undocked changeover tables. During
undocking, a CAN terminating resistor is switched, which maintains the CAN bus function and commu-
nication.
If the terminating resistance is measured with the machine switched off and the changeover tables con-
nected, you will be able to measure 30 Ohms at the Sub CAN bus (with 500kbit/s). Reason: There are
4x 120 Ohm resistors switched parallel. When the machine is switched on, the resistors switched in A3
will be deactivated.

The CAN interface does not have a 4-pin DIP switch at the back, despite it being shown on the corre-
sponding circuit diagrams.
CAN I/O Module (SLIO) - SIPLACE D4/D4i
There are 2 CAN Bus I/O modules in the D4/D4i machine. Both modules are absolutely identical and are
located in sectors 2 and 4.
Function
▪ Micro controller with integrated CAN controller
▪ Data memory
▪ Program memory (flash)
▪ CAN interface with 9 pin connector and address alignment
▪ 16 digital Output 24 V with status LED
▪ 24 digital Input 24 V with status LED
▪ Download interface
▪ Power supply 24 V (for D3: 24 V and 5 V)
▪ Extension on I/O module for the CAN interface (changeover tables)
8 digital inputs can be logically linked with the help of a FPGA (freely programmable gate array). The
FPGA is used for incoming security messages.

NOTICE
Assembly
If the CAN I/O module is fitted again, take care when connecting the plugs, as the greater space
around the plugs can lead to incorrect connection. Incorrect connection will lead to permanent
CAN bus malfunctions and will prevent the machine from starting again.
