Siemens SIMATIC ET 200SP HA - Diagnostics HART; Diagnostics Overflow; Diagnostics Underflow

Information on the measuring ranges and the display with disabled or enabled failure
monitoring can be found in the section "Analog value display (Page 85)".
• If failure monitoring is enabled, the following applies to the measuring range:
3.6 mA < valid measuring range (nominal range) < 21 mA
– Hysteresis at the upper end of the measuring range (detection "Over󹪞ow/nominal
range"):
- The analog value is invalid as of 21 mA.
- The analog value becomes valid again when it falls below the value 20.5 mA.
– Hysteresis at the lower end of the measuring range (detection "Under󹪞ow/nominal
range"):
- The analog value is invalid as of 3.6 mA.
- The analog value becomes valid again when it rises above the value 3.8 mA.
• Diagnostics for enabling failure monitoring
You can enable a diagnostic message for the over󹪞ow/under󹪞ow (Diagnostics over󹪞ow/
Diagnostics under󹪞ow).
If you enable wire break and under󹪞ow diagnostics simultaneously, the wire break
diagnostic is output.
5.4.9 Diagnostics HART
De󹪝nition
Enabling the diagnostics of the HART frame-speci󹪝c monitoring and the status information
supplied by the connected 󹪝eld device in the HART frame (HART device status).
The HART diagnostics are reported as maintenance events.

De󹪝nition
Enabling of the diagnostics for overrange.
5.4.11 Diagnostics under󹪞ow
De󹪝nition
Enable diagnostics for underrange.
