MODBUS input
The register address on the MODBUS slave from which the data is read is specified here.
Name:
MODBUS input
Register ad-
dress:
Specifies the register address.
You will find the permitted address ranges in the documentation of your
MODBUS slave.
Range of val-
ues:
0...65535
Function code: Specifies the MODBUS data type. The following MODBUS data types are
available:
•
Read coils
(read 1 value, 1 bit)
•
Read discrete inputs
(read multiple input values,1 bit)
•
Read holding register
(read 1 parameter,16 bits)
•
Read input register
(read multiple values,16 bits)
Note
Changing the MODBUS input
The function codes are interlocked with certain data types and their number in the S7 CPU
output address.
Note the following conditions when switching over the function codes:
•
Coils / Discrete Inputs → Holding Register / Input Register
Conversion:
–
Data type → WORD
The conversion is now possible.
•
Holding Register / Input Register → Coils / Discrete Inputs
Conversion:
–
Data type → WORD
The changeover of the function code to coils or discrete inputs followed by the
changeover of the data type to BOOL is now possible.
