i am typing in the tag based name eg level1 from a compactlogix l35e, using ethernet ip but the program hangs.
just want to read 1 variable
i can write and integer and write a bit, but reading is an issue directly into the properties of the controls.
can anyone help
it may be your tag scope. I recommend using controller scope tags, but if you want to use program scope, the format has to be like this:
it is a controller scope tag
the text i enter in the "plcaddresstext" is smple igvalue
but it flags and errors every time.
the program halts every time when i want to read and dint or int at the following.
Dim d() As String = ExtractData(PLCAddressByTNS(SequenceNumber).PLCAddress, DataType, ReturnedData)
hope this is of some help to solve what I am clearly doing wrong.
Does it stop and give an error? Or is there just a breakpoint on that line (a red dot in the margin to the left)? If it is a break point, just click the red dot to make it go away.
i dont understand I do nothing really different but it works now
i did click the break point, but i did not put it ther, i guess this is reminance of an earlier problem i created.
all great though.
