3.6.4 Parameter "I-port configuration"

Nominal configuration
3-20
Through the parameter "I-port X configuration" (X = number
of the I-port), the type of diagnostics or error control can be
established for each I-port.
First and foremost, the setting is used for monitoring whether
a device is connected and, if so, whether it fits the configura-
tion presetting.
At system start, the parameter is set to "Use existing device".
This setting can only be changed after the system start.
Devices recognised at system start are saved as the "nomin-
al configuration". This nominal configuration remains intact
even after modification of the parameter "I-port configura-
tion" and is sometimes even used by other configurations.
The following I-port configurations are available:
– Use existing device (standard setting)
Operating mode "Automatic configuration":
A device recognised at an I-port during system start is
stored as a nominal configuration for this I-port. When com-
munication with the device is interrupted, the error "I-port
device missing/failed" is output. If the device is replaced by
another device, this results in an "I-port configuration error".
For more information, refer to section 4.7.1.
Operating mode "Manual configuration":
Communication with the device works in a manner corres-
ponding to the set I/O configuration (the device must
correspond to this configuration). If communication is
interrupted, an error is not output. If the device is re-
placed by another device, various sequences are possible
(see section 4.7.2).
