Using a normally closed contact and (pointer for Boolean array) to enable For/Next loop Causes E01005 System Restart
When using an array with a pointer to enable a For/Next Loop a normally open contact works fine but a normally closed contact will cause CPU P2-550 (E01005 System Restart).
I can use a fixed array tag like "array(1)" with NC contact and it works.
But if I put a tag in the parentheses (I am referring to this as a pointer), it will not work when using NC contact.
I tried it with software ver. 4.5.0 (34) and 4.2.1 (8)
Also tried it with multiple computers and multiple P2-550 CPUs
I can duplicate this issue. Went as far back as 3.12.x.x and can still reproduce. I will report this over to our development team for review.
Workaround is to put your pointer on a previous rung and appears to work as expected.
@LK (Customer) This is the weirdest of issues. Great find.
