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.
