Change PID value TP177Micro ---> S7-226

[ason]

Good evening, i wanna change a PID loop from a Siemens TP 177 Micro panel
and the PLC is a Siemens s7-226

the value for p, i, d, is stored in
VD6 1.0
VD10 10.0
VD14 0.0
they are floating points
and now i wonder how to set it up right on the panel.
i have bean trying almost everything but cant get it right :angr:
i only gets xxxxx on the panel or the closest is 1 when it should be 1.0
what´s the data type and do i need to scale or what?

Thanks,

Hi there
Help file shows that Ti, Td and Kc are all real, that is you need to use VD.
But you are already using this and is getting XXXX so i guess your HMI is not communicating with PLC, What about the other tags?? are they working O.K?
