The meter
INFOCAL-5 by the
Danfoss company. It was designed for the program of
SONOCAL devices to do the invoicing measurings of the heat or cool energy (for temperatures up to 170 C and with the flow up to 25000 m3/h). It has the memory for 24 months. The supported transfer rate is
300/600/1200/2400 Bd for serial link and
300/600 Bd for an optical port.
For this communication in the PROMOTIC system can be used:
If only some selected values are to be received from the meter, then it is handy to use the
PmaCommGroup object. In this object (or by data extension
ExtComm) the variables only for desired values can be defined. The value of the "
ItemId" configurator can be for example:
"sa254.M1.Energy",
"sa1.M1.TemperFor", etc.
For reading the monthly values, the area identifier
"Ia" can be used followed by month index (128=current month, 129=previous month, ... 152=month two years ago). For example
"sa254.Ia128.Energy",
"sa254.Ia129.Energy", etc.
Preset message types for the
PmaCommMsg object:
