INPUT REGISTERS

 (See 

Table 1

 

Modbus register maps

)

The input registers are read-only. 

Table 1

 shows how the data is organized in the 

input register sector. The measured data starts from address 1 (30001) and ends at 
address 14 (30014). The other input registers are not used. When they are addressed, 
they return ‘0’.

All the data can be read by “Read Inputs Registers” command. 

Table 1

 shows 

what the type of the returned data for each register is and the way it should be 
interpreted. For example reading ‘300’ in input register 1 means that the measured 
analogue input signal is 3,0 VDC (or 6,0 mA), reading ‘50’ in input register 2 means 
that the output voltage is 50 % Us (115 VAC).

 

 

Input register 1

 (30001) shows the current value of measured analogue input 

signal. This value depends on the selected analogue input type. When voltage 
input is selected, the values vary in the range of 0—1.000 (0—10,0 VDC). When 
current input is selected, the values vary in the range of 0—1.000 (0—20,0 mA).

 

 

Input register 2

 (30002) shows the current value of the output voltage. This input 

register is overridden by holding register 31 if output override control (holding 
register 8) is enabled. When output override control is disabled, this input register 
shows the value of the output voltage according to the selected operating mode. 
The output voltage values vary in the range of 30—100 % Us (69—230 VAC). 
Reading ‘0’ (0 VAC) indicates that the controller is off. 

 

 

Input register 3

 (30003) shows the type of the analogue input signal. This input 

register is defined by holding register 11 or by the hardware setting of position 4 
of the DIP switch. The values are ‘0’ (for 0—20 mA) or ‘1’ (for 0—10 VDC)

 

 Input register 4

 (30004) shows the selected mode of the analogue input. This input 

register is defined by holding register 12 or the hardware setting of position  1 of 
the DIP switch (

Fig. 4

), according to the selected operating mode. The values are 

‘0’ (for descending mode) or ‘1’ (for ascending mode).

 

 

Input register 5

 (30005) shows the value of the maximum output voltage. This 

input register is defined by holding register 13 or the hardware setting of the Max. 
trimmer (

Fig. 6

), according to the selected operating mode. The register values are 

in range of 75—100 (75— 100 % Us VAC).

 

 

Input register 6

 (30006) shows the value of the minimum output voltage. This 

input register is defined by holding register 14 or the hardware setting of Min. 
trimmer (

Fig. 7

), according to the selected operating mode. The register values 

are in range 30—70 % Us.

 

 

Input Register 7

 (30007) gives information about the OFF level state. In Standalone 

mode it contains the value set by position 2 of the DIP switch (

Fig.  4

). In Modbus 

mode it contains the value of holding register 15. It could be ‘0’ (disabled) or ‘1’ 
(enabled).

 

 

Input Register 8

 (30008) gives information about the OFF level value. In Standalone 

mode it contains the value set by the OFF level trimmer (

Fig. 8

). In Modbus 

mode it contains the value set by holding register 16. This value depends on the 
selected analogue input type and mode. The register values can vary from 0 to 40 
(0— 4,0  VDC / 0—8,0 mA) and from 60 to 100 (6,0—10,0 VDC / 12,0— 20,0  mA). 
The values depend on the selected analogue input type and mode.

 

 

Input Register 9

 (30009) gives information about the kick start or soft start 

selection. In Standalone mode the value corresponds to the start type set by 
position 3 of the DIP switch. In Modbus mode it contains the value set by holding 
register 17. The register values are ‘0’ (for soft start) or ‘1’ (for kick start).

 

 

Input Register 10

 (30010) shows the state of the remote control input. When it 

is disabled, the unit works in normal operating mode. When the remote control 
input is enabled, the controller is in stand-by mode. The register values are ‘0’ (for 
disabled) or ‘1’ (for enabled).

 

 

Input Register 12

 (30012) shows the status of the unregulated output L1. When 

the analogue input signal is below the value of the OFF level (if enabled) or when 
the remote control input is disabled, the output voltage of the unregulated output 
L1 is ‘0’ = OFF (0 VAC). Otherwise it is ‘1’ = On (230 VAC)
