Parameters
2.5. AIFB1
2.5.1. Static Revision No.
The revision level of the static data associated with Analog Input Function
Block 1. The Static Revision No. is updated whenever a configuration
parameter is changed.
2.5.2. Mode
Used to request an operating mode from the Analog Input Function Block.
Allows you to put SITRANS LR560 into Manual mode (used in conjunction with
Simulation) or Out-of-Service mode for maintenance purposes.
We recommend using this parameter only with SIMATIC PDM in order to
benefit from all the features available. For a detailed explanation see AIFB
(simulation, mode and status) on page 127
.
To use Mode via PDM see Simulate Output on page 53 .
2.5.3. Channel
Used to select the Transducer Block output.
Note: Default settings in the parameter tables are indicated with an asterisk (*)
unless explicitly stated.
Note: Ensure that Mode is returned to AUTO when simulation or mainte-
nance are completed.
Setting Description Output value
AUTO automatic the automatically-recorded measured
value
MAN manual a manually-set fixed simulation value
O/S function block disabled the preset safety value
