The advice and opinion given in this thread is that of the author and does not necessarily reflect the views of I S Systems Pty Limited. Should you find that the 'normal' S7 PID Block (FB41) does not quite offer the functionality to replace the S5 implementation,have a look at either ' S7 Standard PID Control Blocks' or ' S7 Modular PID Blocks' library which will offer all the 'bells and whistles' that the S5 blocks had (I doubt that Fuzzy control has been used in your S5, but an S7 Fuzzy Block versionis available too if needed).
I suggest you download themanual for it from HERE,determinethe PID implementation and then implement in your S7 accordingly(rather thantrying to 'crack' and convert these S5 Blocks). While there are ways to overcome this type of protection, there isno need to do so in your case, as your FB69 'Organi' Block is part of a Siemens S5 add-on Packagecalled 'Modular PID and Fuzzy Control'. Siemens used this technique to protect their pre-programmed Standard Blocks from unauthorised access (understandably so, the Blocks are generally well documented and this stopped people from 'fiddling' with their functionality).Ĭertain OEM's andsomeS5 programmers also used this 'Jump over a BE' technique to protect their own in-house developed 'propietary' Blocks. The 'Jump over a BE' command is the S5 way of 'know how protecting' a Block.
