The Hivus communication protocol supports the communication with control units (RJ) and dataloggers (HDL) produced by Hivus. The communication was implemented and tested with control unit the RJ-05e control unit. The control unit is used to time control of performance and regulation of DEZOSTER devices desoster devices (air ozonizers).

  • Category of communication line: Serial, MOXA IP Serial Library
  • Parameters of the serial line:
    • Baud rate: 19200 Baud
    • Parity: optional
      Note: Parity MARK (sending the device address) and SPACE (all others) are set during a transmission, so the parity setting is not important.
    • Handshaking: none

Note: communication on the Serial line was tested on computer serial port, virtual serial port corresponding to MOXA NPort device, and virtual serial port corresponding to Serial/USB converter USB-COM GemBird.
Communication on MOXA IP Serial Library line was tested through the use of MOXA NPort 5450I.

  • Communication protocol: Hivus Controller
  • Station address: 1 Byte.
    Address 0 is "broadcast" (each device responses to it, but only on reading by 02h function). I/O tag - type 105 (logger number) is used to detect the real address of the device.
    Addresses 1-255 represents the common addresses of devices (04h function is used to read data).
  • Time parameters - recommended polling period is 1 min (to avoid loading overloading the processor of the control unit by very frequent communication).

I/O tag configuration

Possible value types of I/O tag: Ai, Ao, Ci, Di, TxtO, TxtI.

I/O tag address is written in the format:

  • T=type - I/O tags without index
  • T=type;I=index - I/O tags with index (channels and signalization of failures on DEZOSTERdesoster)
  • T=type;I=index;J=index; - I/O tag contains raw data of protocol with address 100

The header, which is read from the control unit by the KOM process, contains the information that is mapped into I/O tags without an index (e.g. moto hours worked, number of engaged channels, type of control unit), information about channels and signalization of failures on DEZOSTERdesosters.
There can be configured 0 up to 8 channels. Each channel is defined by characteristics (1-15, see table below), value, upper/lower limit (something like upper/lower limit in D2000). The channels can be addressed in two ways:

  1. consecutive number 1-8:
    • instantaneous value is addressed by T=16, I=1..8 in I/O tag,
    • type is addressed by T=17, I=1..8 in I/O tag
    • upper limit is addressed by T=18, I=1..8 in I/O tag
    • lower limit is addressed by T=19, I=1..8 in I/O tag
  2. order within channels with particular characteristiccharacteristics. Instantaneous value of i-th measurements with characteristic t is addressed by T=t, I=i.
    For example, instantaneous value of third measurement of type 1 [temperature] is defined by T=1, I=3 no matter on which channel this temperature occurs.

Signalization of failures on DEZOSTER desoster enables to read the statuses of DEZOSTER of desoster 1..10 that are connected to concentrator 1 (T=101) or concentrator 2 (T=102).

Example of address: T=8;I=1 - I/O tag will contain the instantaneous value of flow velocity that is first in order. If type 8 (flow velocity) is not configured on any of channels 1..8, I/O tag value will be invalid.

Note: Instantaneous value of the channel can have a flag indicating the unconnected sensor. This flag is mapped to an attribute of "WEAK" value in D2000. If the instantaneous value from the example mentioned above should have a flag indicating the unconnected sensor, it should be probably 0 with an attribute "WEAK".

For example I/O tag with address T=100;I=27;J=29 (bytes 27-29 from the header) contains the type of device (it is the same as I/O tag T=106
