Hello guys, I get the error: i/o access error while updating the process image input table/ output table I know the solution because all my i/o is in the OB1 PI area. I need to define the i/o in PIP area's (416-3 cpu, pcs7 7.1) I've read information and I know the following: - Digital outputs can be assigned to a OB of 200ms or 500ms in most cases - The amount of i/o in a PIP depends on the OB cycling time, it musn't be exceeded - i/o assigned to a PIP area must match the runtime groups in CFC (If PIP2 = OB33, then runtime group of that I/O must be also OB33 I'm wondering how to organize this for all my modules.... How can I divide the PIP? OB32 for all my inputs (DI and AI) and OB33 for all my outputs (DI,AO) and all my CFC blocks in OB35? Also, where can I assign the drives to? Drives are on DP2 and I want to exchange data by using the process image (IW, QW). Can somebody give their opinion about how to organize? Thank you, hope i made myself clear.... |
