Device Profile CiA€-405
This section describes the standardized CANopen€ interface and device profile for IEC 61131-3 pro-
grammable devices, e.g. PLCs. The supported objects for data read/write support signed 8 bit,
unsigned 8 bit, signed 16 bit, unsigned 16 bit, signed 32 bit, unsigned 32 bit and float 32 bit. The cor-
responding objects in the object dictionary can be directly accessed via the buffer memory from the
PLC.
