Hello Sir,

We need some system variables of AXC F 2152.

for example:

PLCMODE_RUN,

PLCMODE_ON,

PLCMODE_STOP...

We have customers who need to do status testing, none of which.

How can we solve this problem?

Thanks!

Hello,

The PLC state is available from the IPlcManagerService2 RSC service - which is accessible from PLCnext components written in C++.

Where would you like to see this information?

Hello Sir,

We are clear about this, but the customer thinks it is too troublesome. They need to call it directly in plcnext engineer.

Martin PLCnext Team

OK. I am not sure what your customer wants. Where exactly does the customer want to see this information? In PLCnext Engineer? On a HMI screen? In an OPC UA client? Somewhere else?

Hello Sir,

They need the system variables to trigger the corresponding function block initialization, and also need to be displayed on the SCADA.

Martin PLCnext Team

Thanks for clarifying.

You might be able to achieve this using one or more Event Tasks in PLCnext Engineer:

For exampe, you can use the "Stop" event to trigger a task that executes a program that sets a variable indicating the PLC state. If this variable is marked with the "OPC" attribute, then the value of this variable can be displayed on a SCADA system via the corresponding OPC UA tag.

Hello Sir,

We will inform the customer after the test and persuade the customer to adopt other methods.

Thank you very much !
