800xA PLC Connect alarming - PLC_Real4
I would to configure a high and low alarm on a PLC_Real4 object in PLC Connect. I can check "use limiter" in the Alarm Event Configuration aspect but the option to check "Is An Alarm" is greyed out and locked to default values (no alarm). Is it possible to enable this alarm? If so how can I enable a high and low alarm on a PLC_Real4 object.
Thank you in advance for your assistance.

For this purpose you have to enable/disable some checkboxes.
First of all,
Under Limiter tab, you have to enable "Use Limiter" checkbox.
Under Event tab, you have to enable "Is an Event" checkbox.
Under Alarm tab, you have to disable "Use Default Alarm Values" checkbox, you have to enable "Is an Alarm" checkbox.
After all you can add alarm expressions with "New" button.
Please find below pictures for details.
Hope it helps you.
