Hello, the block looks like a part of a standard package for something together with other blocks. On the first view the block seems to copy data words from one data block into another data block. That can be simply achieved in S7 with the MOVE function. But there is the paramerter CHNG which is set in this block but is not get reset. Try to find out from which package this block is from. Or maybe somebody knows here. It is possible that you dont need to transfer the block intoS7 while there is another package already existing for the S7. Converting S5 to S7 is not allwaystransferring block by block into S7. And the converter function may be usefull in converting simple logic operations only.I never usedthe converter and use the S5programm just as a reference. Regards.

Q-DB is the source data block Z-DB is the destination data block Q-DW is the start word in the source DB Z-DW is the start word in the destination DB LAE is the length (number of words to be transfered) Before transfering, the block checks if the DBs exists and if number of words can be transfered. ANZW is a kind of error word where the problematic parameter value is displayed in case of error. CHNG is a bit is the transfer was successful. As TIB68 told you, you will not be able to convert this without rewriting the finctionnality in STEP7. Using theSFC Blockmove with variable ANY pointer is the way to go. How to proceed with computed ANY pointers is explained in this FAQ: How do you parameterize blocks, which have "ANY"-type or "Pointer" type parameters http://support.automation.siemens.com/WW/view/en/20443243

MAZEN M004: L MW 210 LIR 1 L MW 212 LIR 1 ><F SPB =M003 L MW 210 ADD BF -1 T MW 210 L MW 212 ADD BF -1 T MW 212 L MW 214 >F SPB =M004 BEA M003: L MW 204 L MW 206 B MW 208 TNW 0 L KB 0 T =ANZW S =CHNG BEA Hi ENG. MAZEN, This block does a 'conditional' block transfer. If there is a difference between source and destination block, then the source block is copied to the destination block and the CHNG flag is SET. If no change is detected the CHNG flag remains unaltered. By doing this, it creates an edge when the source block is CHaNGed. I guess this CHNG flag is resetted outside the FB. But as already stated, S7 offers other options to perform this functionality. Kind regards, BV .

BY 99% YOU DO NOT NEED TO CONVERT THIS BLOCK ! The block ispart of a standard package. Only the siemens developers in germany are using this type of code writing. Is it possible that you can uploadus the whole S5 program? Let me andothersconfirm with you. Would be nice if you can give us even some more information about the existing S5 hardware. If you are not sure, just make a picture and upload it as well. A picture tells more than thousend words. I am looking for some special cards i.e. for communication with other systems. A "flagship" 948 CPU is not just there without any reason in your project. Regards.
