Siemens SIMATIC ET 200SP HA - Diagnostics, Wire Break; Diagnostics Encoder Supply; Hardware Interrupt 1; 2; High Limit 1;2

5.4.12 Diagnostics, Wire break
De󹪝nition
Enabling the wire break diagnostics. A wire break diagnostic message occurs if it is detected that
the current 󹪞ow is too low.
Monitoring is e󹪜ective from an output current of ≥ 240 µA.
If the output current drops below 240 µA when the "Wire break" diagnostics message is pending,
the diagnostic message cannot be canceled until the output current is set above 240 µA again
and the error has been eliminated.
5.4.13 Diagnostics encoder supply
De󹪝nition
The sensor supply of the analog input is monitored for overload and short-circuit to M. To
prevent a thermal overload situation, the sensor supply is switched o󹪜, if required, with cyclical
repowering attempts.
5.4.14 Hardware interrupt 1 / 2
De󹪝nition
A hardware interrupt is enabled if the high limit 1 / 2 is exceeded or low limit 1 / 2 is violated.
5.4.15 High limit 1/2
De󹪝nition
Specify a high threshold which triggers a hardware interrupt when violated.
5.4.16 Low limit 1 / 2
De󹪝nition
Specify a low threshold which triggers a hardware interrupt when violated.
