6.4
Parameterization of modules
The parameters of the XI/ON-modules of one station can be accessed via register range
0×B000 to 0×B400.
For each module in the station, 64 bytes = 32 registers of parameter data are reserved.
The parameterization of XI/ON I/O-modules is described by means of the following examples:
• Example A:
Module 0:
- Changing the measurement range for channel 0 from
"0 to 20 mA" to "4 to 20 mA".
- Deactivation of channel 1 via parameter "channel".
• Example B:
Module 9:
Changing the baudrate from 500000 bps to 71000 bps.
Example A:
Module 0:
The parameter of the module (1. slot in the station) can be accessed via registers 0×B000 to
0×B01F.
1
Changing the measurement range for channel 0 from "0 to 20 mA" to "4 to 20 mA".
The module shows the following parameter data structure (1 byte of parameters per
channel):
