Hello Chris, The S7-300/S7-400 devices have an important group of functions for event handling. In the process part (PCS7) this is handled intensively.
At the time, all these operations are on the Tag associated with the request, so any service type subscription is a subscription to events. In general the S7-300/S7-400 support; - *MODE*: Change of operating state in the controller, change from STOP to RUN and vice versa. - *SYS*: System events, associated with internal events of the controller or events previously parameterized for their indication. - *USR*: Events programmed by the user and that are registered in the internal diagnostic buffer. - *ALM*: Alarm events generated by the user program, ALARM_S, ALARM_8, NOTIFY. - And additionally "*CYC*" cyclic mode transfer. But in general they are all seen as events, hence the inconsistency pointed out by Bjorn. All these events are implemented, of course, they have many points of improvement that must be addressed. I currently do not have a PN or CP-343-1 CPU for testing with S7-300. As you point out, with Zylk's contribution it can complement the CP-443-1 for redudance tests (thanks Zylk). Well, the story is long... I'm going for a good coffee.
