Several days ago we installed a new vision 230 pls. Earlier we have the same pls but unfortunately because some technical issue we need to install a new one.
So finally we install it, load a old program from previous pls and unfortunately we have some problems.
Our pls read the data from electrical and water meters and then send it to e-mail at end of the month.
Since we installed a new pls some of the data are missing
for example:


Flat Cold Hot

01 115.258 0.000
02 59.079 49.297
03 235.354 0.000
04 0.000 0.000
05 153.646 90.032


Tthis zero is not correct data reading.


And finally it won't send us data to e-mail .
Have you some ideas why on the same plc and with the same program we have this problems.


if you need additional info please ask!


program is attached.

Did you reinitialize and clear the operand values before downloading the program into the new PLC? If this was not performed than any values left over in the memory of the new PLC will still be there, and can affect the program. It is possible that this is the issue.


I would recommend reinitializing the controller and seeing if this solves the issue.


If the data you are seeing is wrong, is there any screen on the HMI where you can change it?


The program itself does not know what values are needed and may need to be entered manually in order for correct operation.
