Dear Ste39

Good day

thanks for your kind support and I wonder  how can you know the N.W.59 on FC2 concerning about Slave Nr.12 , where it I&Q as I understand the input bits I256~I263+I264~I275 for output Q256

~Q263+Q264~Q275 ? 

You know what I asked ? I asked about tools or how can search for i/p and o/p for this program or similar one .

regards 

Dear Daniel

Good day 

kindly check attach Pic. and how can I search for I256 and Q256 on my program ,where I searched about it multi time and I can't find it .

regards 

Hi, I normally use SF14/SFC15 to read/write to a DP Slave. In your case the Adressing is inside the FC254 Network 10 and 11. You can´t find PIW256 or PQW256 because your program is using some indirect addressing, PIW [AR1,P#0.0].

In the Networks mentioned by Ste39 you could see the the block has an input named ADDRESS, this value is read inside the block FC254 in the Network10. It has some programming for Reading the 20 Bytes from the Slave beginning with 256, 276 or 296. The data is transfered to a DB assigned in every called Block. Each block has an input called DB_Block, there you could see were is transfered all the data for every Slave. DB97, DB98 and DB99.

Hope this helps.

Dear Syd

Good day

thanks for your information, i read you instruction and manual but still miss understand how can finds the address on my program from H.W ?

thanks for your support

Hello,

Kindly have a look at the following topic:

indirect addressing and cross reference

fritz

I suggest you create a source file of all blocks to begin with.
To do so, open any block(e.g. OB1), go to the File menu,select "Generate Source", choose a name for the source file (e.g. "All_Blocks"), select all Blocksand click on OK.

Thereafter, open the source filewhich will now allow you to do a text based search through the whole program for all the indirect addressing related usual suspects (e.g. terms like "AR1", "AR2", "[", "]", "P#" etc.).
If you know theI/O address, you may also want to search for the INT address number of the peripheral input(e.g. 128 if it is PIW128) as well as the HEX address number(e.g. 80 if it is PIW128) in case this is used for example as a parameter for an FC.
