This protocol supports data acquisition (in the case of SOFTCONTROL and OMOS devices, also data writing) from both the heat meters and control systems produced by OneSoft s.r.o. Prievidza.

The communication supports and was tested for these devices:

ELTRONIC, FC200 ST, FC200 WM, FC200 GS, MAXTRONIC 05, MAXTRONIC 15D, STEAMTRONIC B, STEAMTRONIC D, SOFTCONTROL, OMOS

• Communication line category: Serial, SerialOverUDP Device Redundant.

• Serial line parameters:

  • Baud rate (it depends on the device settings),

  • Parity (usually none parity),

  • Handshaking depending on the type of converter RS232/RS485. Set Transmit and Receive delay to approx. 60 ms for the converters that are controlled by RTS signal.

• Communication protocol: OneSoft Devices

• Station address requires to set these parameters:

  • Device ID (from 0 up to 65535).

  • Data block size (see Table 2).

  • End of range for calculation the checksum „Checksum after: “ (see Table1).

Table 1

In the configuration dialog window of the station, you can choose a device that presets the values from Table 1.

For SOFTCONTROL devices, the setting of data block size is different than block size for calculating the checksum depending on firmware in the particular application. We recommend you to ask for technical documentation from a producer. At the end of the data block you can find the following information:

From this information, it results that the value for "Data block size" and "Checksum after" is 316 (the number of transmitted bytes is in fact 315+1). 

OMOS devices do not need this parameter. You can set zero values. When configuring OMOS stations, remember that the device consists of several separate modules. Each module is configured as a separate station. See the parameter of station protocol "OMOS ICS module".

OMOS devices can be time-synchronized - the parameter "Synchronization period" on the tab "Time parameter" in station configuration should be enabled.

These parameters influence some optional parameters of the protocol. You can set the following station parameters:
