  1. Product:             STEP7 Professional V13 Reference:           FB Declaration Static: Data type TON is not allowed here Description: ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Hi, I'm using Step7 Prof V13 SP1 upd7 & WinCC Adv V13 SP1 upd7.    In my project I'm using a 312CPU, Article No.: 6ES7 312-1AE14-0AB0, Version: V3.3 & TP1500 Comfort, Article No.:6AV2 124-0QC02-0AX0, Version:13.0.1.0   My Issue: I've taken previously used FB from my Global library and inserted it into my new Project. In this FB I've declared an IEC Timer (TON) in the static section of the FB. When I go to upload to the PLC after TIA carries out the compilation I get error message 'Data type TON is not allowed here'. I've tried creating a new FB to test and had same issue for CTU,CTD,TOF.   See attached pics This is really strange as it has always functioned before! Has anyone seen or heard of this issue before? I'd appreciate any help, Cheers.
  2. S7 Graph step selection

    Hi all, I'm using S7 graph and I would like to be able to jump to a step after a warm restart of the PLC. This is to be able to carry on from the step the sequence was in before the restart. I have figured out that I can select a step in Manual mode. So if during the warm restart I pulse a bit for the input to SW_MAN then Load an INT value representing the S_NO before the restart into S_SEL and then pulse another bit into SW_AUTO. Will the sequencer carry on like normal in auto mode from the selected step?
