MODBUS REGISTERLISTA
Input registers
Data type Description Data Values
1Actual Temperature Level signed int Actual temperature. 200 = 20.0°C
2Current Output Duty Cycle signed int Current output in % 0-100 100 = 100%
3Selected Setpoint signed int Current setpoint in °C 50-300 300 = 30.0°C, 5—30°C
4–9 Reserved. Return 0.
10 Setpoint Source Selected
(Ext.SP / Int.SP) unsigned int Shows which setpoint is used - external by analogue input or internal
by trimmer or Modbus register 0,1 0 - External; 1 - Internal
11 Working Mode (Slave/Master) unsigned int Shows how the controller is working: as a Master providing analogue
output for a Slave device or as a Slave when the output in % repeats
the analogue input 0,1 0 - Slave; 1 - Master
12 Day / Night Mode unsigned int Shows which setpoint is active: selected by NO switch 0,1 0 - Day; 1 - Night
13 Remote Off Contact unsigned int Shows if the device is in remote off: selected by NC switch 0,1 0 - On, 1 = Standby.
14 Control Board Problem Shows if there is problem with the communication with the control
board 0,1 0 - OK,1 - Problem.
15–18 Reserved. Return 0.
Holding registers
Data type Description Data Values

Enhetens parametrar kan övervakas / konfigureras via den kostnadsfria 3SModbus-
programvaruplattformen. Du kan ladda ner den från Senteras webbplats. Det finns
två typer av register i en Modbus Registerlista:
Input register (se tabell Input register ovan)
Input register är skrivskyddade. All data kan läsas med kommandot "Läs Input
register”. Tabellen Input register visar den returnerade datatypen och hur den ska
tolkas.
Holding register (se tabell Holding register ovan)
Dessa register är läs- / skrivregister och de kan hanteras via kommandona "Läs
Holding register”, "Skriv enkel register" och "Skriv flera register". De register som
inte används är skrivskyddade och därför returnerar skrivning i dessa register varken
ett Modbus-felundantag eller gör det några ändringar.
