Communication

Pre−operational

When the slaves are switched on, they assume the status
pre−operational" and wait for the master. This status serves
exclusively for parameterising via SDOs.

Operational

After parameterising has been carried out, the CANopen
master can switch slaves into the operational status with a
special network management telegram (NMT).

In this status, communication via SDOs and PDOs is possible.
With the aid of the NMT telegrams you can switch between
the states.

The PDOs of the SFC−LACI are assigned as follows:

1401h

RPDO 2

1800h

TPDO 1

Ĉ transmission type = 255

1)

Inhibit time = 0

1801h

Ĉ Inhibit time = 0
Ĉ event timer = disabled

1)

asynchronous transmission (event triggered)

This parameterisation corresponds to the asynchronous
(event triggered) transmission which is standard with most
masters. Conversion to e.g.Ăsynchronous transmission is
possible if the communication parameters are written with
the appropriate values from the DS 301 communication proĆ
file, but modifying the mapping is not possible.
