Very nice post indeed Aret as for this:
While I can't currently say how a real PLC will behave (don't have one handy to test), but PLCSIM does certainly "complain" about the "1" that is being shifted by the SRD 4 into the part of the pointers address area that should (or must) contain 0's. Attached is a pic which has two examples, one with using "IW 4"and one with using "PIW 4" as the FC's input Parameter. Note the AR1 address of 131072.2 that is created out of the SRD 4 of "IW 4"! |
