Hey all. I have a few FC blocks that run well on the Siemens PLC[314C-2DP], but as soon as I add the OB33 [500ms interrupt] interrupt with a SFB47, the block doesn't download to the PLC. See attached code for the OB33. Can anyone please assist.
As the previous post, check the properties of the CPU to show which cyclic interrupts are available and to set the time interval. The 314 only has OB35 as shown below:
