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.

  • I have the latest version and use drivers, ADPRO, KOYO, MODBU and MOTCP. For some of the PLC's which do not seem to handle real numbers properly I have to use the driver sheets. This seemed to take a lot of effort, and then I found that once you have a few PLC's on the sheet it would be difficult to spot tags you have already created. When I discovered tag integration was able to keep all your devices separate, I then started using it with no problems. It is only now on this PLC that I am having problems with the temperature cards.

    With a bit of luck I managed to find a version of the tag export CSV file which seemed to work all the time. This only had half the tags in it, so I manually started adding the missing ones until I had the full set. This was working last night, so I continued on with working on other parts of my program. This morning the temperature readings have stopped again. This is what the output window is saying.

    [ID: 63CC] ADPRO Read Block - Station: 172.20.5.104;.\Tags_CSV\Ammonia Compressors_basic.csv, Address: TAG:Head Temp 13 and 14 On 16 cyl to TAG:Head Temp 15 and 16 On 16 cyl > Invalid block size [05/05/2020, 08:24:01.708ms]

    I may add these values to the driver sheet and see if they work properly there. The fact that I do not see any way of separating the PLC's is just a bit confusing for me. I have used KEPServer and liked the way it was structured.
