Re: Reg:Warning related to vartype

Dear Sharath,

Some more precisions on the second warning you are getting:

>   ***** WARNING ***** 
>   UNIT/TYPE/INPUT/VARTYPE  CONNECTED TO  UNIT/TYPE/OUTPUT/VARTYPE 
>   --------------------------------------------------------------- 
>    18     2     3   TE1       --------->    25   164     1    SF1 
The "SF1" signal is a non-standard unit added by the HYDROGEMS Types. It 
appears to be used for a volumetric flowrate in Nm3/h, although the 
output 1 from Type 164 is a volume in Nm3... We will correct that in the 
future.

The Type 2 controller essentially works by comparing inputs 1 and 2 and 
setting the control signal based on the thresholds you give as inputs 4 
and 5 (input 3 is a used for the high limit cut-out). So, as long as you 
use a consistent set of signals for your controller, it will work fine.

The most common use of controllers is for temperatures, which is why 
Type 2 expects to receive a temperature ("TE1").

Kind regards,

Michaël Kummert
