FIELD DESCRIPTION
Info1 Input/output type. The authorised values are:
•1:analog input (0-10V or 4-20mA)
•2: digital input
•3: switching relay output
Info2 Input/output number. The authorised values are:
•1 to 3: if “Info1” equal to 1 (analog input)
•1 to 4: if “Info1” equal to 2 (digital input)
•1: if “Info1” equal to 3 (switching relay output)
Info3 Clarication on the input or output type.
•If “Info1” equals 1 (analog input), the authorised values are:
1: analog input of the 4- 20ma type
2: analog input of the 0-10V type
•If “Info1” equals 2 (digital input), the authorised values are:
1: ON-OFF input
2: S0 pulse input
•If “Info3” equals 3 (relay type), this eld is not used

3.1.2.2.2.2 Modbus
FIELD DESCRIPTION
Info1 The type of register read. This type results in the function codes that will be
used to read and write the data. The authorised values are:
•1: “coil . The modbus read function code will be 0x01. The write function
code will be0x05
•2: “discrete inputs“. The modbus read function code will be 0x03. This type
is for input reading. Writing is therefore not possible.
•3: “holding register”. The modbus read function code will be 0x03. The write
function code will be 0x10
•4: “input”. The modbus read function code will be 0x04. As this type is for
input reading, there is no associated write function.
