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).

Communication line configuration
...
- 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).
...
Configuration dialog window - Communication station - field "Protocol parameters".
These parameters influence some optional parameters of the protocol. These The following parameters can be used:
Tab. č. 1
Key wordKeyword | Full name | Description | Unit | Default value |

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:
- 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
- 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).

Table 1 - I/O tags for channelstyp | Ai, Ci, Di | Reading of instantaneous value of measurement of typ type, which is index-th in order.Index can be from range 1..8.Type can be from range 1..15 according to table below:Type | Description |
---|
| Temperature (°C) | | Relative humidity (%) | | Ozone concentration (ppm - parts per million) | | Pressure (kPa) | | Flow (m3/hour) | | Air quality (ppm) | | VOC - Volatile organic compounds (ppm - parts per million) | | Flow velocity (m/s) | | Toxicity (%) | | Intensity (%) | | NH3 concentration (ppm - parts per million) | | CO concentration (ppm - parts per million) | | State of blocking sensor (0/1) | | Dew point (%) | | State of the fan (0/1) |
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". |
| Ai, Ci, Di | Reading of instantaneous value of channel with index. |
Index can The index can be from range 1..8. Example of address: T=16;I=2 - I/O tag will contain the instantaneous value of channel 2.
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". |
| Ai, Ci | Reading of channel characteristics with index. |
Index The index can be from range 1..8. Example of address: T=17;I=2 - I/O tag will contain the characteristics of channel 2.
Note: The characteristics can be from range 1..15 with the meaning stated in the table or invalid |
, if no sensor is connected to the channel. |
| Ai, Ci | Reading of upper limit of the channel with index. |
Index The index can be from interval 1..8. Example of address: T=18;I=2 - I/O tag will contain the upper limit of channel 2.
Note: The value is invalid |
, if no sensor is connected to the channel. |
| Ai, Ci | Reading of lower limit of the channel with index. |
Index can The index can be from interval 1..8. Example of address: T=19;I=2 - I/O tag will contain the lower limit of channel 2.
Note: The value is invalid |
, if no sensor is connected to the channel. |
Table 2 - I/O tags - raw data from the protocol
Address | Value type | Meaning |
---|
| TxtI | Reading the raw data from the protocol header into the text I/O tag. "I" and "J" |
indicate indicates the beginning and end byte (1-128), and this condition must be valid: I<=J. For example I/O tag with address T=100;I=113;J=128 (bytes 113-128 from header) contains a comment from printer (it is the same as I/O tag T=110). 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 ).
Note: These I/O tags are intended for specialists and for future extension of the protocol. |
Table 3 - I/O tags relating to fault conditions of dezosterof desoster
Address | Value type | Meaning |
---|
T=101;I=indexT=102;I=index | Ai, Ci, Di | Reading of signalization of device failure with an index that is connected to concentrator No. 1 (if T=101) or concentrator No. 2 (if T=102). If the index is from the range 1..10, the I/O tag value will contain the information about the failure on a particular |
dezoster desoster (according to the value 0/1, False/True). If index=0, the I/O tag will contain the information about all 10 |
dezosters desosters as integer (status of |
dezoster bite dezoster bitebit) Example of address: T=101;I=2 - the I/O tag will read the failure signal of |
dezoster desoster 2 that connected with concentrator 1. Note: If the information in the protocol contains a bit, which signalizes "concentrator is not connected", the value of the I/O tag |
is Table 4 - I/O tags without indexes

the writing is supported (the protocol function |
of protocol 05h). Note: This I/O tag is also used to set a control band, blocking sensor, signalization, language, to switch manual/ |
automat automatic mode, to set parameters of modes, etc. For more information, see the documentation for communication protocol. |
| TxtO | Writes values to control unit (by protocol function 01h). Supported values:- time - format of value: Thhmmss (hh-hour, mm-minute, ss-second), e.g. T142030 means a time 14:20:30
