text: <s>[INST] PLC programming mode status to SCADA. I want to sent a high signal to SCADA when PLC is in programming mode.Somebody else made programs and I am commissioning now. There is a tag for CPU1 and CPU2 programmming mode in tag table. I did crpss reference and I cannot find where from it came. Also I have a redudent L75 PLC. When I turn the key on CPU and made program mode, I did not get program mode tag high to HMI. Its value is 0 and not getting high.why? [/INST] In Program mode the program does not run, so no values will change. Here, I have used a GSV to get the Status of the controller. When the controller is in Program Mode, as shown, the instructions don't run, so the values are as they were when it was last in Run mode. You haven't said what SCADA system you are using. If you are using FactoryTalk View SE then there are some tags you can read to get the status. They begin with @ and you can find a list in the documentation. You could look at the @Mode tag. If you are using a different SCADA package, check its documentation. You could use GSV instructions an ladder to get information about the Controller status. You are using a redundant processor, so you ought to be able to get information about each controller from the Redundancy object. So if if the Secondary is in Program mode you should be able to find out.\n </s>
