Mike, What browser and pdf viewer are you using. I cannot get the file to download. Thanks.

That is a Chinese only product. I am told if you install CX-Programmer with Chinese language, you should be able to connect. Good Luck. gtsuport

You are correct. I am unable to download Jay's GRAYCODE.pdf. Guessing that is the plc logic you would need. gtsuport

Adapter  CJ1W-CIF11 would be needed on the cpu serial ports.  RS232 spec is 50 feet, pretty sure it would not go 1000 meters. You could use HOSTLINK, but you would need to format the strings. Might be easier to use Protocol Macros.  CX-Protocol is used to create the protocols.  Another software to learn. gtsuport

My suggestion would be to connect the HMI to the SCU unit. Do you already have the SCU's? You can set the SCU for Host Link mode to talk to the HMI. PLC Link will be the easiest way for the PLC's to communicate. How much data are you trying to transfer?

Just my two cents. Probably your best bet would be to use CJ1W-CIF11 RS485 adapters on the cpu serial ports. That way you could use PC Link. gtsuport

900 mm = 34.4 inches ? I agree with you Mike, it could be times 4 for quadrature.

What is the diameter of the roller? Diameter * 3.14 = circumference of the roller Circumerfence / 1024 = distance per pulse.

Hi Jay, I cannot seem to download the file. Would you mind PM to me please? Thanks gtsuport

CJ2 plc has a GRY instruction to do this.

budiman, Welcome to the forum. Do an internet search on gray code to binary plc logic. The E6CP has a gray code output and you will need to convert that to binary for use in our plc program. gtsuport

Welcome to the forum. I think you will need to jumper RTS - CTS on the PLC side. Should be pins 4 and 5. gtsuport

Please see the attached. Serial PC Link CJ2M.pdf

You will need to use the Data Link Area of memory for the communication to work. Data Link Area is CIO 1000 to CIO 1999. gtsuport

khoi, 80CF is an I/O bus error.  Check the interconnection of I/O modules. 0F0F is not showing in the manual. Please refer to manual W393 for further information. gtsuport

Welcome to the forum. Only one device can be connected to RS232. 1) Yes you can connect to a GUI or HMI. 2) Yes.  Please see information on Serial PLC Link in the W472 manual. gtsuport

Look at parameters b001. Also C001, for Start options, 2 wire or 3 wire.

Wiring  W450 manual  

Dip switches are only for DeviceNet speed, reference manual W377. What USB to serial converter are you using?  Not all are created equal. gtsuport  

You will need to contact the OEM or original programmer to get the password.

Yes, the CS1W-CN226 should work. USB to RS232, not all adapters works correctly.  You can try to see if you adapter works. If not, I would suggest the USB CN226 cable from  www.plccable.com https://www.plccable.com/omron-plc-programming-cable-usb-cs1w-cn226-cs1wcn226-usb-version/ Jeff

CQM1H dip switch information is attached.

Try connecting Ethernet FINS. Port can run both simultaneously. gtsuport

Trimjohan, Check the plc start up settings. The controller may be seeing the terminal as a programming device and starting up in Program mode. You should be able to set start up mode to Monitor. gtsuport
