Multiple messages sent and received not working

We are trying to read from a external CAN device (a  Axiomatic ax020510 for proportional valve control ) and send 4 messages across the CAN to the Murphy PV450.    We have a state machine that determines outputs. We then want to write back to the same device across the CAN bus

In both the read and write we have problems with the message(s)

• Request 1: How do we get the Axiomatic CAN settings to line up with Murphy CAN?
• Request 2: Is this configuration even correct for sending commands over CAN and getting readings back over CAN?

Extra information:

-The problem is that we can see messages being sent on the CAN bus from the Axiomatic via the CAN sniffer. The murphy reads the first packet (FreeFormCAN.Demand), but displays the default value of the variable (419397632), while it should be 0-255 by script.

-It is not reading any of the other variables. FreeFormCAN.PressureHigh, FreeFormCAN.PressureSuction, FreeFormCAN.IVS. We just see a greyed out signal, meaning error (no connection).

-We do not know how to enable those three signals in the murphy.

-The murphy screen we are using is the PV450. The external valve controller is the Axiomatic AX020510.

For receiving commands from Murphy:

for the axiomatic device, it has its own setup
