3.7.7 Verify Communication between the Quantum Processor and
the Gateway
In this step, you will verify that the processor and the gateway are communicating
with each other over the Modbus TCP/IP Ethernet network. The sample project
includes an animation table called MNETDPV1_Table. When the processor is in
RUN
mode and communicating with the gateway, the values in this animation
table are updated whenever you trigger a GetModuleStatus read message to
request general gateway status from the gateway.
To verify communication between the processor and the gateway:
1 Place the processor in R UN mode, if you have not already done so.
2 In the Unity Pro Project Browser pane, click [+] to open the A NIMATION
T ABLES tree, and then double-click MNETDPV1_T ABLE .
3 In the MNETDPV1_Table, you will see three main variables which can be
expanded to see many more sub-variables.
4 Look for the variable, MNETDPV1_StatIn. Click the [+] next to it to open it
and see all the sub-variables. These will include configuration information and
version/revision information, which will remain static, as well as program scan
counters, input/output update counters, request/response counters, and
others variables that should change whenever you trigger a status calls.
