228 System Manual, 12/2015, C79000-G8976-C253-04
Function code: Specifies the MODBUS data type. The following MODBUS data types are available:
• Write single coil
(write 1 value, 1 bit)
• Write multiple coils
(write multiple values,1 bit)
• Write single register
(write 1 parameter,16 bits)
• Write multiple registers
(write multiple parameters,16 bits)
Default setting:
• MODBUS output
– Function code: Write single register
• S7 CPU input address
– Data type: WORD
– Number: 1
Note
Changing the MODBUS output
The function codes are interlocked
with certain data types and their number in the S7 CPU
input address.
Note the following conditions when switching over the function codes:
•
Multiple Coils ↔ Single Coil
If you select the number 1, you can switch over between single coil and multiple coils by
changing the data type from BYTE to BOOL and vice versa.
•
Multiple Registers ↔ Single Register
If you select the data type WORD and the number 1, you can change over between
single register and multiple registers.
With the other constellations for changi
ng over the MODBUS output, note the following
sequence when changing the parameters.
•
Single Register → Single Coil
Conversion sequence:
– Single Register → Multiple Coils
– Data type → BOOL
The function code switches automatically to single coil.
•
Single Coil → Single Register
Conversion sequence:
– Data type → WORD
The function code changes to multiple coils. It is now possible to change over to single
register.
•
Multiple Registers → Single Coil
Changeover first to single register (see above) and then to single coil
