Same here, large projects or image heavy projects can take a while even over LAN, we have one we use on a regular basis that takes ~42min to download and burn the upload.

Is the F2 fuse for the IO board blown?

You need a program the EX-RC1 is a PLC with limited ability. Send an email to support@unitroincs.com and they will be able to provide the version of the Visilogic required. Then you can try uploading the EX-RC1 program. Also double check that the jumpers for the EX-RC1's unit ID are set correctly on the new unit.

The only 9 pin connector I can think of is a DB9 for serial communication, which would require a USB-RS232 converter. RS232-CB1 is the RJ11 to DB9 cable from Unitronics and then you'd need a USB-RS232 convertor with a prolific chipset

No the PLC doesn't need to be in a specific mode in order to upload, Run mode or Stop mode either is fine. If you know which version of Visilogic the program was originally written in you can try using it, however a newer Visilogic will upload a project written in an older version. As for the run-time errors, I haven't ever had that issue. I'd suggest taking screen shots and sending and email to support@unitroincs.com.

There is no simulation program available for Unitronics OPLC's

The code is basically the same across the entire vision series, the V700 differs in how the Ethernet is configured due to the onboard ports.

Take a look at the UniDownloader software tool. It lets you create compressed download files to send a customer so they can update PLC's with out seeing the ladder code or needing Visilogic. You can even include an O/S update if needed.

I’ve seen PLC brick during O/S updates but never during a program down load. A EX-RC1 is basically a stripped down V120. I’d try the following 1) what baud rate is your communication set to? If you communicating with an EX-RC1 it should be 57600 2) If you can’t get communication established with the EX-RC1 via a serial link , yet you are able to communicate with the V280. You should be able to use the V280 as a bridge to talk to the EX-RC1 over the CanBus connection. You would need to look at your communication setting and change from a direct connection to a Within Network. Then select the ID of the node (in your case 2) to communicate with. Try getting the OPLC information. It should come back with the EX-RC1. You should now be able to down load as normal.

No you can't, you will need a copy from the original programmer.

Modbus is always explicit. The master has to issue the read and write commands

More than likely when the power failed there was a surge that damaged something in the controllers power supply stage. I'd contact your distributor and see if they can help you obtain a new unit, return the existing for evaluation to determine what did happen.

As long as they support Modbus RTU (Serial connection) or Modbus TCP(Ethernet connection) then yes once they provide the register map you should be able to establish a connection and pass data.

Do the HMI's show anything on them or is it a black screen? If it's a black screen I suspect the power outage may have taken out the power supply on board. if you remove the back cover check the on board fuse with a multimeter and see if it's blown.

You might be able to get it to connect to the IP address, however you not going to be establish an IO connection to pass data with explicit or implicit messaging as the Vision series doesn't support Ethernet/IP protocol. It supports Ethernet TCP/IP (which is something entirely different), or Modbus TCP as Ethernet communication protocols. Unitronics built Ethernet/IP communication into the UniStream series of controllers, I'd recommend contacting your local distributor and seeing about getting one of them to do this as it supports the required protocol.
