There are many different objects divided into the following groups:

Ratings and Reviews

Kirkkerekes ,

Too buggy to bother with.

This app is basically abandoned and bug-riddled.

Just for example, the 2012-added “Force Multiple Coils” appears to have no function, as there appears to be no way to get multiple values into it, and single values generate a runtime error “ a little "red 1→?” that is undocumented.

Additionally, the overall execution speed is very slow, and the app regularly loses track of what is going on — errors persist about objects that have been deleted from the workspace.

The developer needs to at least test every function before calling the app done.

Developer Response ,

Dear Kirkkerekes, 

Force Multiple Coils has been added because certain devices do not support Force Single Coils. Of course, only 1 coil is always controlled, but with a different Fcode.

The speed of oPlc is adjustable via the Preferences menu.

If you have problems or do not fully understand certain matters, please send us an e-mail so that we can help.
