10.2.3 Access to parameter data
At initial start, parameterisable modules are operated with their default parameters. If you want to
set parameters, you can parameterise the Modbus TCP bus coupler or the plugged I/O compound
modules via a web page.
10.2.4 Access to diagnostic data
In the event of an error, I/O compound modules can provide alarm data. As soon as one or several I/
O compound modules report an alarm, the alarm data of the respective slot are received and
acknowledged by the Modbus TCP bus coupler which then sets a bit assigned to the Modbus TCP
slot in its internal "Alarm Information Image" and saves the corresponding alarm data.
In the I/O system 1000, it is made a distinction between diagnostic alarm and process alarm. For this
purpose, the diagnostic image has one 64 bit wide field each (bit 0 = Modbus TCP slot 0 to bit 63 =
Modbus TCP slot 63) for process alarm and diagnostic alarm. They are followed by a 16 byte slot for
process alarm data and 32 byte slot for diagnostic alarm data.
For acknowledgement, you also have writing access to diagnostic and process alarm status. The
alarm data can only be accessed by reading.
