4.3
Substitute value behavior
The substitute value behavior is implemented by the DP master per slot in the ET 200SP
distributed I/O system.
The respective output reacts according to its configured substitute value behavior:
● Current-free/voltage-free
● Keep last value
● Output substitute value
The substitute value behavior is triggered in the following cases:
● STOP DP master
● DP master failure (connection interruption)
● Firmware update
● Station stop, for example, due to:
– No server module
– At least one I/O module installed on an incorrect BaseUnit
● Deactivate DP slave
Note
Reducing a configuration
If you reduce the configuration of the ET
200SP distributed I/O system and download the
new configuration to the CPU, the modules no longer configured but still
present retain
their original substitute value behavior. This applies until the supply voltage on the
BaseUnit BU...D or on the interface module is switched off.
The "current-free/voltage-free" behavior takes effect in the following cases:
● Firmware update
● Configuration control: receipt of a new control data record
● Incorrectly configured module
● Module with incorrect parameter assignment
