● Select a measurement input for a measurement using a Timer DI. The selection box
displays all channels that have been configured correctly.
Note
Extending the configuration limits
A maximum of eight timer DI can be configured at the X142 interface. If the timer DI at X142
are not sufficient for your needs, you can configure a further eight measuring inputs at
interface X122/X132. You can also extend the configuration limits using time-based I/O
modules:
• ET 200SP distributed I/O system: TM Timer DIDQ 10x24V
• ET 200MP distributed I/O system: TM Timer DIDQ 16x24V
You can find more information on these systems in Technology functions of the CPU
(Page 44).
