Communication with meters Danfoss INFOCAL-5

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:
- Reading of measured values:
There are following variables on the "Data-received" tab: Header of M-BUS message CustomerNr (customer identification number), Energy (accumulated energy [GJ]), Volume (accumulated volume [m3]), Power (instantaneous power [kW]), Flow (instantaneous flow [m3/h]), TemperForward (Forward temperature [°C]), TemperReturn (Return temperature [°C]), TemperDiff (Temperature difference [°C]), OnTime (number of days since switched on), Date (current date and time), Error (see the note above).
- Reading of Monthly Report:
There are following variables on the "Data-sent" tab:
Address = meter address
MonthIndex = month index (128=current month, 129=previous month, ... 152=month two years ago)
There are following variables on the "Data-received" tab:
