BITS N BYTES

IMHO you are making this task more complex than need be. Many of todays VFD's have built-in PID routines that are available. You would send an analog signal from the MASTER to the FOLLOWER VFD and use the PID setup in the FOLLOWER VFD, no need to mess sround with trying to do it in the PLC. You haven't stated which model VFD you are using so don't know for sure if it has built-in PID.   My 2 Cents  

For Heaven's sake buy the correct cable for programming via the peripheral port. Don't even waste your time trying to make it. P/N is CS1W-CN226. Just google it and there are many resources to purchase the cable at reasonable cost. If your computer doesn't have a Serial Port then you will also need a USB to Serial converter. This model has never failed me with CJ1M PLC's. http://www.serialcomm.com/USB_adapters/USB_converters/usb_to_rs232_adapter/usb_to_rs232_adapter.product_general_info.aspx

Your gonna spend a ton of bucks on the NC213 module vs. upgrading to the latest CJ2M CPU with CJ2M-MD21* Pulse I/O module. Mt 2 Cents.

The CJ1M is an old unit. Replacing it with CJ2M-CPU and one or two CJ2M-MD21* Pulse IO Modules is a far better option for High-Speed counters and Pulse control outputs. IMHO you are going to waste a ton of time messing with the CJ1M for your application. My 2 Cents.

If the porgram was created in your version 9.50 or earlier then an update probably won't fix your problem. First try a full auto update and see if that fixes your issue. Failing that a complete uninstall followed by Clean CXOne, then a complete reinstall and a complete auto update is probably your only solution. Very tedious and time consuming but as a last resort should ultimately fix your problem.

Opens fine for me in CX-Programmer V9.65

It's in the PLC instruction manual. Increment ++/++L Decrement --/--L Remember to use a rising edge LD instuction ahead of the Decrement instruction.

The CP1E N20 will NOT handle any analog signals or expansion models. The CP1E NA20 does have TWO analog adjuster inputs built-in.

My personal preference is to use the APR instruction vs. SCL. http://forums.mrplc.com/index.php?/topic/30950-proble-with-scale-function-in-cp1l/#comment-145675

Personally prefer to use IR pointer vs SRCH (181). Faster scan time, Attached is update program. Note that D0 to D2000 is 2001 loops.   Count result of data memory >0 is in D2100   Word Search Greater than D0-D2000.cxpWord Search Greater than D0-D2000.cxpWord Search Greater than D0-D2000.cxps.  

Use a FOR/NEXT loop with Index Register. See attached example:- At rising edge of W0. Searches 10 words D0-D9 for value greater than 0. Place result in D100. Word Search Greater than 0.cxp

Have you configured the PLC settings correctly AND ternsferred them to the PLC AND performed a power cycle. Analog input data for AD CH0 should appear in CIO 90.

The OMRON Automation Software Upgrade Utility has worked flawlessly in the past for updating CX-One and Sysmac Studio. Just got a new update for Sysmac Studio 1612_0101 , it will not complete and indicates install is aborted. Anyone else had a similar problem and/or suggest how to resolve this?

Just tried opening Sysmac Studio for a new project and I get this message. Any ideas how to work around this issue. VERY FRUSTRATING!    

Yes that works, but in my opinion much cleaner to have all memory areas cleared when starting a new project.

NOT AUTOMATICALLY that I know of. The method I use is to copy desired addresses from CX Programmer Symbols and paste into EXCEL. Edit EXCEL spreadsheet to add/change desired name then paste back into CX Programmer. A few words of caution:- There is some conflict with WORD and BIT addresses you need to be aware of. For example CIO Word 0 and CIO Bit 0.0 will both appear as 0 in your spreasheet.

OMRON has posted many tutorials on You Tube .

When online select PLC from upper menu bar. Select "Clear All Memory Areas"

Why are you using FLOAT variables. HSC increments/decrements by INTEGERS not FLOAT. Remember position in PRV is a double word value, in your case D1 and D2. Your program is overwriting D2 in rung 1 with the *F(456) instruction. Not a good programming practice..

No problem. Send via private email if that works for you.

Post your programme and I'll test whether it opens in my CX-Programmer version!

Use the Event Display function.

Unit number in your program is 0 and Operating data area designation is allocated to SIOU in the PLC IO Table. Check rotary switches on position control unit are set at 0. Starting DM area for this position control unit starts at DM2000 and CIO Operating memory starts at CIO2000. You need to modify your program to map to the correct areas.
