Parameters
2.4.2. Fail-safe Mode FB1 (FS MODE FB1)
Fail-safe Mode occurs if the status of the input value is bad, or if the device has
been put into Fail-safe mode using Simulation. One of three options can be
selected for the material level to be reported when the LOE timer expires.
2.4.3. Fail-safe Value FB1 (FS VALUE FB1)
Accessible in SIMATIC PDM only after Substitute value is selected in Fail-safe
Mode FB1 (FS MODE FB1)(2.4.2.).
User-defined default for the Output Value, if sensor or sensor electronic fault is
detected. Units are the same as the AIFB1 units.
2.4.4. Fail-safe Mode FB2 (FS MODE FB2)
Fail-safe Mode occurs if the status of the input value is bad, or if the device has
been put into Fail-safe mode using Simulation. One of three options can be
selected for the material level to be reported when the LOE timer expires.
2.4.5. Fail-safe Value FB2 (FS VALUE FB2)
Accessible in SIMATIC PDM only after Substitute value is selected in Fail-safe
Mode FB2 (FS MODE FB2)(2.4.4.).
User-defined default for the Output Value, if sensor or sensor electronic fault is
detected. Units are the same as the AIFB2 units.
