Modbus address type

Modbus Slave address

Masters can address individual slaves, or can initiate a broadcast message to all slaves. Slaves return a response to all queries addressed to them individually, but do not respond to broadcast queries. Checking the manual should provide information about the slave address, specially if device supports multiple slave addresses. If there are no informations about individual slave address, you can leave the slave address at default (Value = 1).

DPT Boolean

Node converts the data from Coils and Inputs table, defined by the Table setting.

DPT Double

Node converts the data from Input Registers and Holding Registers table, defined by the Table setting. The data can be converted from IEEE 32 Bit Float, Signed 16 Bit Integer, Unsigned 16 Bit Integer or Signed 32 Bit Integer. In case of IEEE 32 Bit Float and Signed 32 Bit Integer, 2 holding registers (4 bytes) will be read.

DPT Integer

Node converts the data from Input Registers and Holding Registers table, defined by the Table setting. The appropriate data Address should be entered. The data can be converted from Signed 16 Bit Integer, Unsigned 16 Bit Integer or Signed 32 Bit Integer. In case of Signed 32 Bit Integer, 2 holding registers (4 bytes) will be read.

DPT Unsigned Integer

Node converts the data from Input Registers and Holding Registers table, defined by the Table setting. The appropriate data Address should be entered. The data can be converted from Unsigned 32 Bit Integer. 2 holding registers (4 bytes) will be read.
