Answer

It means the parameter 1_P6511 has to be placed later in the PCM. The parameter 1_P6511 is placed at the beginning of the PCM. It means the KAM- 500 has to schedule this parameter very early in the acquisition cycle. The parameter has to be transmitted at tick 12 (125ns =1 tick) but this parameter needs more time to be scheduled on the backplane.

Check if the parameter is coming from a bus monitor module. If it’s, ensure all the parameters from the same message are placed horizontally in the PCM to ensure the usage of BDMA.
