Joe, Thank you immensely for all of your help! I appreciate you taking the time to fully write out an explanation to what is required out of UniCan and what changes you made. The communication between all of the modules is working flawlessly now. Thank you again, Greg

Thank you for your help. I have tried downloading your code to the V570 and still cannot get the RO to trigger. I know the addressing is important dependent on the equation: 32 + (expansion module number) * 16 + (output number). So in my case I have the RC1, then the DI16, and lastly the RO16. So the first output O1 should be addressed at O49. Please advise. Thanks, Greg

Hello all, It has been a while since trying to interface with the RC1 and IO modules. I was working with a snap-in IO module in the meantime. I want to get these modules working as well. I have attached the .vlp files with my adjustment to the EX-RC1.vlp for my application. I am not sure what to be adjusting on the V570 file to be able to actually control the DI16 and RO16. Please advise. Thanks, Greg EX-RC1.vlp V570_CAN Master for EX-RC1.vlp

I was not supplying 24V DC to the CANbus wiring, so I have fixed that. Thank you Denis. I also did have the switches inverted because of how I read the documentation drawings. It is now correctly set to ID 2. Thank you Joe. I am now able to communicate with the EX-RC1! Moving forward for programming the EX-RC1 to work with the V570, since I want to use the IO-DI16 and IO-RO16, can I just change the HW configuration in the sample EX-RC1 file to those modules and then create a program for the V570? Thank you both for all of your help.

Yes, I do get to that pop-up window. When I set the Unit ID to '1 (CANbus)' and I click the Get OPLC Information, the V570 information shows up as it should. However, when I change the unit id to 2, I get the pop-up window with the list of errors for CANbus. I do have the DIP switches on the EX-RC1 set to 2. I am not sure why it is not able to establish a connection.

Hi Joe, Yes, I have realized this. I have made more strides in becoming more familiar with the V570 and EX-RC1. My current problem not is a problem with communication with the EX-RC1. Before attempting to download the EX-RC1.vlp I attempt to check the connection and get errors. I have the EX-RC1 connected with a CANbus cord between the V570 and EX-RC1 with the EX-RC1 set to 2 on the dip switches. So when changing the communication through the USB cord to UniCAN channel 2, this is where I am receiving the errors. Can I program the EX-RC1 through the V570 with a cord between the 'PRG' port on the EX-RC1 to either Port 1, Port 2, or the I/O expansion port on the V570? Also while still downloading from my PC to the V570. Thanks, Greg

Hey all, I am new to Visilogic and I am trying to follow through tutorials. I am currently trying to interface a single EX-RC1 via CANBus to a V570. On the EX-RC1 I have a IO-DI16 and IO-RO16. I have tried to download the sample Visilogic programs to the PLC, however, I am not entirely sure if I am doing it correctly. I have flashed the V570_CAN Master for EX-RC1.vlp on the V570 successfully, however, the screen shows "COMM ERROR UNIT #2". When I tried to download the EX-RC1.vlp to the PLC it says "The PLC model selected in this project's Hardware Configuration conflicts with the model with which you are communicating." I am programming through the USB cord to the V570 with a baud rate of 115200. Any and all help would be greatly appreciated. Thanks, Greg
