4.3.7 CAN I/O Module (SLIO) - SIPLACE D4
There are 2 CAN Bus I/O modules in the D4 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
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.

4.3.8 CAN Bus Communication with Axis Controller
4-16: Overview axis controller
In previous Siplace placement machines, the communication and data flow between axis controller and
machine controller was achieved using the SMP bus. From the HF machine generation onwards, the
SMP bus is no longer used with the axis system.
The communication between the axis controller modules is now achieved using the CAN Bus. All the
information exchanged between these modules is transmitted via the CAN bus (e.g. axis parameters,
target position, end position signal ...). This means that the number of individual telegrams increases
significantly over time, compared to the amount of data in older machine generations.
The axis control system is divided into:
Axis control I and II for gantry and main axes, plus
Axis control III for "remaining head axes".
Axis control I and II communicate directly with one another, via the interrupt lines for the anti-crash
monitoring system. The data communicated is the two Y gantry axis positions and the axis states.
