An issue has come up at a plant where interlocks are being bypassed by forced I/O.... Specifically this relates to prox switches which detect the proper position of piping connections in order to prevent CIP and Product from mixing...
Does anyone know of a way to detect specific forced I/O...?... I know that it is possible to detect if there are any forces, but I have not found a way of detecting individual ones...
We try to keep programs without any forced I/O as it causes problems, but it just keeps happening... A tech will force some I/O because they really need to finish a production run or they don't have the part to fix it or they are just to up to their ears to deal with it...
Thanks,
John
