Good day pals! Can I ask something about the CC-Link Network? I have a concern regarding cross-communicating two CC-Link Masters using MC Works Master PC. Can you guys help me with the system architecture? Thank you very much. Your help will be greatly appreciated pals. Thanks a lot.

Good day sir. I am trying to figure this out. Somehow I did some progress, but this is far from complete. I came to use FOR NEXT statements and I saw in the programming manual that there are existing logical ops that might help me. I am now trying to figure out the stuff that must be programmed inside the ladder to complete the process as it has a time prerequisite (It was a MARKEM printer on a high speed horizontal wrapping machine. I will update you regarding the stuff.

I use ladder programming, in GX Works2 sir.

The PLC is Q12PHCPU and I use GXWorks2. Thank you sir.

Good morning people! May I ask if there are some sensei in ladder programming that can help me interpret this code to a ladder program. Initialize CHECKSUM as FFFF(Hex) (There is a FOR NEXT Instruction) FOR each Byte CHECKSUM = CHECKSUM XOR (current byte) FOR I = 0-7 If ((CHECKSUM AND 1) = 0) CHECKSUM = Right_Bit_Shift CHECKSUM 1 bit Else CHECKSUM = (Right_Bit_Shift CHECKSUM 1 bit) XOR A001(Hex) NEXT I NEXT Byte I hope you can give me some ideas on this guys. I need some CRC function on the machine I am programming and I find it hard interpreting it in a ladder program. Thanks guys.
