IEC870 variable

IEC870 variable

Good day, I have a variable that arrives in ICCP protocol, from origin they gave me the following data: iccp datatype - Analog plus quality plus timestamp extended / datakey: 1 / scope: system / Slope: 1.
Therefore I configured with driver iec870, but I can't see the signal in the servers, in the configuration of the type identification I used the T31, is it correct to use this protocol?  Or would you have to use a process gateway to be able to read the signal correctly?
