This information should be clearly indicated within the PLC manual. If you don't have a copy of the manual then try either the Siemens PLC website (which has the manuals and application notes) or a google search of the PLC model in question.

for the basic functions of editing data from the memory you can also use move, read and memory pointers.

Hello LANGAX01PRO,

I believe that you have a S5 series siemens PLC ans Not the S7 series and you will need S5 software to communicate with the PLC. S7 PLCs 300 and 400 series.

Hi there,

First of all the S7 range - S7-200;300 and 400.

If you are working with this range. Do a google search for: S7gsv54_e.pdf and download it. It is a step by step guide on how the simatic manager software works. I would suggest though, that you contact your local Siemens branch and attend a few courses as the Siemens PLC's are way different to anything else. They have a whole lot more functionality than what most people are used to.

Regards,

Craig
