I have a P3L30 with the 87L function missing from the protection menu. From information on the SE website this may be hidden due to something else being missing. Please could someone suggest what the missing element might be, I've looked but can't spot it?

Hello @IMillican ,
Good day..!
You have to select ANSI 85 under COM1 port protocol in order to see 87L differential function in protection menu. I have attached the snapshot of COM1 port menu for your reference.

Hello @IMillican ,
Probably your device is not having differential communication card, please check optional card I details.
