The transmitted value is displayed with or without flashing, depending on whether the value

lies within or outside the alarm limits, and the set alarm logic. The flashing interval is set in

the parameter PF.

6.4

Any exceedance of the alarm limits is displayed by flashing LEDs in accordance with the

alarm logic.

∩-Logic (parameter AL.t = 1) − the display flashes if the current value lies within the interval

(Т – Δ) < t < (T + Δ),

whereby T − is the setpoint of the monitored process value (parameter C.SP) and Δ − is the

hysteresis (parameter HYST).

U-Logic (parameter AL.t = 2) − the display flashes if the current value lies outside the

interval

(Т – Δ) < t < (T + Δ).

If the parameter AL.t = 0, the function is deactivated.

For the String (dAtA = 3) and Image (dAtA = 4) data types alarm logic is not implemented.
