Type: uint(16bit)
(uint (16bit), int (16bit), uint (32bit), uint (32bit) sw, int (32bit), int (32bit)

[5]
[1]: Ordinal number from 1 up to 100. If several sensors are connected to one sever, then
Query is sending to consecutive sensors in order resulting from the ordinal number.
[2]: Selection from the list of added servers (configuration in the
Servers
tab). It is allowed
to assign the server which mode is set as
Disabled
.
[3]: Slave device address from which the data will be read.
[4]: Set the register's number from which data will be read. Available format: 3xxxx / 3xxxxx
or 4xxxx / 4xxxxx, where: 3
input registers, 4
holding register and xxxx / xxxxx
four / five digit address. To speed up the communication, set consecutive register’s
numbers in increasing order. The value must be given in decimal system (see section
MODBUS RTU / MODBUS TCP TRANSMISSION PROTOCOL
Notes:
It is possible to group registers, which speeds up the data transmission. If the
order of addresses for consecutive registers is retained for one device and the
value in the field Type
[5]
is chosen so that the sums of the values of the Address
and Type are consecutive numbers, then one Query can obtain a value for
several consecutive registers within one communication frame.
[5]: 10 formats of readings are available in the drop-down list, where: uint
– unsigned
integer, int
– signed integer, float – single precision floating point, double – double
precision floating point, sw
– swapped format (more information in section
Choose a format that matches the specification of the sensor or device you are reading.
12.3.4 RS-485 port
Recorder RS-485 port settings must correspond to the master device settings.
Baud Rate: 19200
(2400, 4800, 9600, 19200, 38400, 57600, 115200)
[1]
Parity: NONE
(ODD, EVEN, NONE)

ModbusRTU Address: 1
(1, .., 247)
[3]
[1]: Baud Rate should be set to the highest possible value. For high distances or high
interference level, data transmission speed may need to be decreased. Low
transmission speed extends the reading time.
[2]: Parity control of each bite.
[3]: In RS-485 standard, up to 32 transmitters / receivers can be connected to the data
transmission line. Each slave-type device must have a different address assigned.
For more information on Modbus registers addresses and data format refer to section
MODBUS RTU / MODBUS TCP TRANSMISSION PROTOCOL
12.4 Channels settings
The channel number is selected using the drop-down list, located in the upper left corner
of the screen. The description of the channel can be edited by clicking on the text in
Tag
field. Then, the screen keyboard will pop up.
For commissioning channels settings there are six settings tabs available: Inputs,
General, Alarm 1, Alarm 2,
Σ1, Σ2.
