J1939 DM1 signal on CR711S

[sbiughy]

Hello,
using CR711S I have tried to map DM1 signal of diesel motor by J1939 driver. On Codesys, however I have seen that there is only the first DM1 message available (see picture attached).
Is there some special command on codesys to update the DM1 data?


(in the picture it is available only a SPN alarm, but there were active two alarms.)

You have to use the DM1_Read function block from the IoDrivJ1939 library from Codesys.
