Slovenc Posts: 27 Rating: (3)	I have foung a sample project that includes the GET/PUT blocks. Now i have a problem converting my data types. I want to convert bool to word. I found the block for converting but it does not include bool or word types. I attached a picture where you can see the block i found for converting.

I found the block for converting but it does not include bool or word types. I attached a picture where you can see the block i found for converting. Thanks for your help, Jure Hi Jure, I am hoping you wish to convert several bits into a word and not just one bit into one word. METHOD 1 _{#my_bit0 M501.0 ---\| \|------------( ) .....repeated for all bits #my_bit15 M500.7 ---\| \|------------( )} . . . . . . . . . . . . . . . . . . . . . Then use MW500. METHOD 2 _{#my_bit0 #my_word.x0 ---\| \|------------( ) .....repeated for all bits #my_bit15}_{#my_word.x15 ---\| \|------------( )} . . . . . . . . . . . . . . . . . . . . . Then use #my_word. This method is called slicing. METHOD 3 Advance method.. using AT overlay. (I will not go into detail for this one.. either method 1 or 2 should work fine.) Please consult the S7-1200 System Manual for more info about Slicing and AT overlaying. Greetings. w

Slovenc Posts: 27 Rating: (3)	As you said i want toconvert several bits into a word.I want to know where i can get the block for converting bool to word. I found a picture of a bool-to-word block so you can see what i mean. I really apreciate your help, Jure Attachment Zajeta slika.JPG (5977 Downloads)

Then maybe, there is something else to learn. Find attached the source code with instructions on how to import it. okay? [smile] Attachment Bits to Word code and instructions.zip (4141 Downloads)

Slovenc Posts: 27 Rating: (3)	Ok i converted the bool type to word. Now when i get the word from PLC 2 with the GET block do i need to convert the word back to bool so i can read the data that i sended?

Now when i get the word from PLC 2 with the GET block do i need to convert the word back to bool so i can read the data that i sended? Okay.. The easiest way to do this is use the SPLIT method: As an example the format of #MyDB.MyWord.x0 would extract the first bit. In a sense it is the reverse of the coding I gave you in my last message. Or would you want the coding to make an FC for that? w Attachment BreakWordIntoBits.zip (1854 Downloads)

Slovenc Posts: 27 Rating: (3)	I made a FC block to convert the woord to bool. Ok this is what i have dont till now: In PLC 1 i have created a GET block. In PLC2 i made a bool to word block and stored the word as seen in picture i uploaded. In PLC1 i have made a FC which converts the word back to bools so i can use them. Did i do everything ok till now? Have i stored the SEND_DATA correctly? How do i acess to the word in PLC 2 (i need the adress of the SEND_DATA) Attachment Converting.jpg (2849 Downloads)

How do i acess to the word in PLC 2 (i need the adress of the SEND_DATA) Please review the image you attached.. this is the original image you started this thread with and contain no FC blocks. The image you have there now does not add to your description, IMHO. The GET and PUT commands like to have words to send, it is for that reason you asked your bit-to-word and word-to-bit questions. Remember your original thread about GET function was split to this one. Continue on with your original thread {LINK}. I would suggest also you add the project files to the thread. Make the project to have only the pieces for the communication. Remember to ZIP the project before you try and add it to your post. Good luck. w
