mapp Services V5.16

This function block uses the MpLink from an MpJ1939Generic configuration.

The parameter group numbers (PGNs) defined in the MpJ1939Generic configuration are transmitted and received on the specified CAN interface using MpJ1939Generic. The CAN interface is defined in the MpJ1939Generic configuration under "CAN interface". How data is transmitted and received is explained in section Transmitting and receiving information.

Some PGNs must be sent in certain cycle times. For more information, see Timing.

The informational structure displays diagnostic information of the function module.

If signals in PGNs have scaling or an offset, they are automatically adjusted when transmitting and receiving the PGN. For example, signal EngRequestedSpeed_SpeedLimit in PGN TSC1 has a factor of 0.125. This factor is automatically taken into account when transmitting and receiving the PGN.

A PGN can also have minimum and maximum values. These are also taken into account automatically. If a PGN is transmitted in which a value would overshoot the maximum value of the PGN, then error Value outside limits is triggered and the value cannot be sent.

If and which scaling or offset a PGN has can be taken from a PGN database.
