MODBUS compatible addressing description
The first 255 bytes of cyclic input and cyclic output data are available over the MODBUS
addressing. If the software address is < 248 in ASCII Modbus mode or < 99 in RTU Modbus mode,
the rotary switches are ignored and the software configurable address is used.
Note: The Address “Zero” is not supported and would cause a red ST LED.
Configuration
All Parameters for the communication are defined at the 'Com Interface Object' [ComIfc].
The delivery settings are:
Default settings
Parameter Modbus
Software Address 248
Baud Rate 9600
Parity 1 => even
Data Bits 8
Stop Bits 1
Failsave Timeout 0 (not used)
Config 1 => MODBUS compatible RTU
protocol
Configure the protocol.
0 Æ Human Readable Protocol, see RS485/USB Protocol
1 Æ MODBUS compatible RTU protocol
2 Æ MODBUS compatible ASCII protocol
Parity
Define the parity setup.
0 => none
1 => even
2 => odd
DataBits
Define the data bits. Possible values are for:
ASCII 7 or 8.
RTU 8.
