Diagnostics Hart; Diagnostics Overflow; Diagnostics Underflow - Siemens SIMATIC ET 200SP HA Equipment Manual

Parameters
5.4 Explanation of the module/channel parameters
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 "Overflow/nominal
– Hysteresis at the lower end of the measuring range (detection "Underflow/nominal
• Diagnostics for enabling failure monitoring
You can enable a diagnostic message for the overflow/underflow (Diagnostics overflow/

Diagnostics underflow).

If you enable wire break and underflow diagnostics simultaneously, the wire break
diagnostic is output.
