Please read the attachment about SFC58,SFC59 to undrestand their operation and requirement much better.The LADDR is module base address which can be found in H.W config editor. More information about SFCs here: System Software for S7-300/400 System and Standard Functions Volume 1 and Volume 2 Regards AttachmentSFC58_59.pdf (1668 Downloads) |

Hello, What impacy you mean in your question? LADDR is just an address. If you entered correct, you will get the correct values, if not then you may get wrong values from other device and address it in wrong field in HMI / SCADA or make wrong processing. Or you may put a value in LADDR not exist in the HW config, so you will get zeros. So, you have to put this value correctly. That's all. Hope this helps.

Please read the manual related to the function, for LADDR you need a variable in word in Hex and you will find more if you check the file shared by MarcJan.It is start address of input/output that slave share with master on process image. Using slave address is wrong here.
