Database Spy Usage

Admin
When in design mode does the Database Spy show the values of tags or have you to do something extra. Any tag I have entered here show a value of zero and the connection Quality is good. When used in the program the tags show their true value.

Another problem I have is with tags reading the temperature from a PLC. These have been working up until I decided to do a Verify. This came back with no issues, but I have not been able to get the values from the PLC since then. This is where the Database Spy is confusing as it says the connection is good. The same PLC has other analogue inputs and these are showing up OK. The PLC is not faulty as a touch screen is able to show the temperatures.

Should I just reinstall Indusoft. I also thought that the output window could be cleared by right clicking on it, but this does not give any options.

  • That does appear to be the problem, although before I reinstalled i think it definitely was not working. The first screen does not show the menu. The second screen, which is where I am designing has the menu of to the left. If i am close to the LHS it will appear on the first screen. On the third and fourth screen it appears just below and to the right of where I right click.

    Thanks for that.

    My Next problem is how to get the tag values back. As I said, they had been working up until I did a verify. They did come back for a while, but because the program was complaining about missing tags I did another verify and that seems to have stopped them again. It is all the input cards for temperature measurement which are not working. If I copy the value on the PLC to another tag I can see them and the PLC is working properly. I have other PLC's with a similar setup and these have no issues with the temperature cards. I might just change the PLC to see what happens.
