Fleet Management System Interface, PSM, Function - GF54.21-S-3005TRA

Model 447

With Code ED5 (Parameterisable special module)

Except Code XM7 (MOPF II)

Model 448

With Code ED5 (Parameterisable special module)

Except Code XM7 (MOPF II)

The fleet management system (FMS) only contains messages to be sent by the parameterizable special module (PSM) control unit (N26/16).

These messages contain the following vehicle status information, for example:

Vehicle speed
Engine values
Driver information

International organization for standardization = ISO.

ISO11992-2/3

This standard contains send and receive messages. The send messages contain information similar to that for the fleet management system (FMS), with the addition of some items of engine information. The signals received by the parameterizable special module (PSM) control unit (N26/16) are stored in the signal pool and can, for example, be used for working speed control.

Freely assignable messages

The freely assignable messages are output as follows:

In the send direction, 4 messages ("GPM_1H", "GPM_1I", "GPM_1J", "GPM_1K")
In the reception direction, 4 messages ("GPM_2H", "GPM_2I", "GPM_2J", "GPM_2K")

The send signals are assigned from the signal pool. The receive signals are stored in the signal pool to await further use. The signals are given the designation "AuxBit, AuxByte" etc.

Details can be found in the document "Signal lists, PSM, function".

Activation of the freely assignable messages is only possible if the message package ISO11992-2/3 has also been activated. Otherwise, the send messages of the PSM control unit ("GPM_1H", "GPM_1I", "GPM_1J" and "GPM_1K") are not sent.

Structure of messages:

8 bit signals
2 byte signals
2 2-byte signals

Cycle times of sent messages:

2 x with 100 ms
1 x with 500 ms
1 x with 1000 ms

The precise contents can be found in the "CAN matrix" in the documents "CAN matrix, PSM, function".
