  1. Hi, When I run my HMI trend curves it displays from right to left, is it possible to change the display from left to right. Regards JJ
  2. Joe, I have done the changes you suggested, which is good as now i'm not getting any error messages regarding communication as my status message is "0". But the return value at "MI 23" is fluctuating between 0 and 1, I need the value to return the PV display of the shinko Temp. controller value of 23 degrees or whichever the PV display is. As i'm logging that value into a Table and a Running curve. Attach is my code of my PLC program. thanks for your help. JJ PLasticorder PL200 v12.vlp
  3. Hello, I'm still having issues to connect and read the "PV" value of the Shinko Temperature controller using Modbus Protocol. The parameters set are the following; PLC - V570 Modbus ASCII Communication speed 19200bps Data bit/Parity 7 bits/Even Stop Bit 1 Slave ID #65 and Slave address 0100H and I have change the dip switches to RS485 on V570 Shinko Temperature controller Modbus ASCII Instrument number 65 Communication speed 19200bps Data bit/Parity 7 bits/Even Stop Bit 1 Response time 10ms See attached Shinko documents and a screen shot of the ladder diagram. When I try to read PV value I’m getting an error message of no communication established (Status Message goes from 4 to 5). I have been communicating with Shinko Japan and we have checked my wiring and settings all seemed to be ok. But they mentioned that the PLC need to send this command 020401000000F9 CrLf, This is where I'm not sure how do that. If you could help it would be greatly appreciated. Regards JJ serial communication shinko remp controller.pdf
  4. Kikis, Yes Shinko's BSC2 temp. controller serial connection for Modbus ASCII start Bit 1, Data Bit 7, Parity Even, Stop bit 1, and communication speed 38,400. V570 Com port 2is set to RS485. What I'll need to know now is how to put this in the ladder diagram. Hope you can help me, Thanks
  5. Hi Simon, Thanks for the quick reply. The equipment i'm working on has been wired by a previous company and we've been asked to re program the V570, to give them more options when they run their test. The thermocouple type J is connected to a Shinko temperature controller BSC2R0006 which has a serial output which is connected to V570 Port 2 as shown on the photos below, which could be COM2. The serial output is 4-20mA and type J thermocouple range is -200 to 1200 degC. I guess what i need to know if V570 port 2/com2 can read analog signal and how do we program on V570. If you can help that will be greatly appreciated. JJ
  6. I'm creating a new program for this system which is already wired up, the thermocouple is connected to the Port 2 of the V570. How do I read the data from the port and for the data to be converted into Degrees Celsius. Thanks JJ
