4.9 Analog Input (AI)
4.9.1 Simulation
Simulate replaces the channel value coming from the sensor transducer block. For testing
purposes, there are two ways to manually drive the output of the Analog Input Block to a
desired value.
Manual mode
To change only the OUT_VALUE and not the OUT_STATUS of the AI Block, place the TARGET
MODE of the block to MANUAL, then change the OUT_VALUE to the desired value.
Simulate
1. If the SIMULATE switch is in the OFF position, move it to the ON position. If the
SIMULATE switch is already in the ON position, move it to OFF and switch it back to the
ON position.
Note
As a safety measure, the switch must be reset every time power is interrupted to the device to
enable SIMULATE. This prevents a device that is tested on the bench from being installed in the
process with SIMULATE still active.
2. To change both the OUT_VALUE and OUT_STATUS of the AI Block, set the TARGET
MODE to AUTO.
3. Set SIMULATE_ENABLE_DISABLE to ‘Active.’
4. Enter the desired SIMULATE_VALUE to change the OUT_VALUE and
SIMULATE_STATUS_QUALITY to change the OUT_STATUS.
If errors occur when performing the above steps, make sure that the SIMULATE jumper
has been reset after powering the device.
