Hello Gandalf and Welcome to the forum;

You will have to get used to Siemens warning and error messages; they are very litteral.

Yhe message states that there is a missing Boolean operation for this instruction (actually for all Timer and Counter instructions).

See for example how member Mountaineer programmed his networks with the TON instruction, in the attached document:

Hope this helps,
