6.3.5 Locking/unlocking operation
Once you have entered all the parameters, you can lock your entries against unauthorized
and undesired access.
Locked operation is indicated as follows:
• By the symbol on the onsite display
• The parameters are grayed out in FieldCare and the handheld terminal, which means they
cannot be edited. Indicated in the corresponding "Lockstate/STATUS_LOCKING"
parameter.
Parameters which refer to how the display appears, e.g. "Language (000)", can still be
altered.
If operation is locked by means of the DIP switch, you can only unlock operation again by
means of the DIP switch. If operation is locked by means of the operating menu, you can only
unlock operation again using the operating menu.
The "Operator code (021)" parameter is used to lock and unlock the device.
The release code is defined in the "Code definition (023)" parameter.
6.3.6 Simulation
Simulate the output of the Analog Input Block as follows:
1. Set the "Simulation" DIP switch on the electronic insert to "On".
2. In the Analog Input Block, select the "Active" option by means of the "Simulate/
SIMULATE"
record parameter, "Simulate En/Disable/ENABLE_DISABLE" element.
3. Enter the value and status for the "Simulate value/SIMULATION_VALUE"
and "Simulate status/SIMULATION_STATUS" elements. During the simulation, the
output value and status of the Analog Input Block are replaced by the simulated value
and status. The Output/OUT parameter shows the result.
4. End simulation (via "Simulate/SIMULATE" record parameter,
