Hphillips (Customer) asked a question.
I have a click plus C2-03. When I first received it, I was able to connect to it with the latest software. I was walking through a tutorial trying to teach myself how to program PLCs and one of the steps in the video was to update the PLC firmware. It failed a few times but eventually I was able to get it to 100% but it failed again, this time on the 2/4 phase(main CPU) update. Now I can no longer even connect to the CPU.
The connection test passes.
The button to Blink ERR and RUN button does make the lights blink
I have tried multiple USB micro cables.
I have deleted AppData folders, uninstalled all drivers, uninstalled the software. Rebooted my computer several times.
Reinstalled the software and drivers.
I have also factory reset the CPU both using the software app and holding the BT button for the 5-6 seconds.
I have done all of these steps without any modules installed and while in STOP mode.
The CPU is recognized as a Click Plus on the COM port in device manager when plugged in. I then try to connect to the PLC. I am greeted with a message that the firmware on the PLC is a higher version then what the programming software supports (this doesn't make sense as I am on the newest software v3.92). I am given the option to either download the newest software from the website, or to "downgrade" the firmware to 3.92. When I attempt to "downgrade" to 3.92 that is when I am met with the PTC-005 error.
I have tried to use an older version of the software(v3.71) and am met with the same error.
I would also add that the ERR light does come on when I power the unit on. When I power the unit with only the usb cable the ERR light comes on solid after 6-8 seconds. If I power the unit via 24V the light comes on immediately. If I factory reset the module while it's powered on via 24V, the ERR light will go off but comeback solid 6-8 seconds after the CPU restarts.
Is there anything I am missing?
You should try the software based reset tool first. If this does not work you will need to replace the PLC through an RMA. The solid red Err indicator is a self-diagnostic error, so the failed updates may have rendered it inoperable.
When doing a firmware update always make sure to have the PLC connected to a power source providing 24 volts (23 is too low). This will ensure a smooth update in the future.
Thanks, I was able to get a hold of v3.31 and downgrade to that version which has seemed to work.
Where can I find version 3.31? I'm having the exact same issue.
Did the version of 3.31 we sent you work out ok?
Yes, installing 3.31 and then upgrading to 3.92 worked for me.
@ADC_Tech_03 (AutomationDirect) I'm having the same issues. I can't find a version of 3.31 to try the downgrade, any chance you can send it to me please?
It appears you received a copy yesterday from our technician Jim? Is that correct? If not I will send a link.
Yes, thanks for following up, Jim sent me the link and I got it all updated so I'm all good. Just for anyone reading this in the future, here's what I did to get it working:
Reinstalled firmware using 3.31 via usb
* Updating to 3.92 over usb continued to fail even though usb connection is good
Connected via ethernet and attempted the update to 3.92 a couple of times, eventually it worked!
So I'm all good now. Thanks everyone.
