1 Introduction

The APCI-8001 / APCI-8008 control units can be optionally fitted with a CanBus interface. The CAN
bus is connected at connector P2. RWMOS.ELF operating system software which contains the
"optionMSM9255" option must also be used. The APCI-8001 / APCI-8008 can only act as a master
and does not have an object directory itself.

2 Functions of the CanBus option

2.1 Initialisation

Access to the CAN function is via the "universal object interface" of the APCI-8001 / APCI-8008.
