Hi to all,

Im trying to write a screen number to a OP7 so that when the cell is placed into Automatic the Diagnostic screen automatically activates. I believe im on the right track but i need some advice as all is not going to plan. banghead

Heres what ive done so far:

Ive defined the Interface Area in Area Pointers in protool and used a seperate Datablock in S7.

According to Protool help i need to activate PLC Job 51, so i write 51 to the data area,the screen number to parameter 1 and the number of with screen within the screen i want to display.

testing this in a vat, The OP responses with "Please wait" and then returns to the original screen before this.

I wonder if anybody can shed any light on this?

Thanks in Advance

Steve
