[?+] : programming S7-400 using CFC: OB85-86-87

Post by ciwa »

Hi..
I'm trying to programming S7-400 using CFC, how to add interrupt OB85,86 & 87?
if add these OB in offline folder and download to the PLC, CFC always delete these OB when I compile the CFC.
"W: the empty OB87 in the beginning was deleted. it will be create again if it is included in the automation block installation."
I just want PLC not stop when missing profibus node.
Please advise.

Regards,

Ciwa

Create empty FB or FC.
Right click on FB (FC) -> Object properties -> Attributes.
Add attribute 'S7_tasklist' and set value 'OB85, OB86, OB87'.
Add this FB (FC) into CFC chart.
When you compile CFC, compiler create this OB's.
