Hi,
I'm trying to reset an unresponsive 1769-L30ER, made more difficult by the fact that I'm separated from it by 100 miles. I have VPN but that's only partly useful.
The LEDs are flashing such that the 1769 may have either a recoverable or unrecoverable error (not very helpful error definition !).
A power cycle has been tried several times - to no avail.
An attempt has been made to find the PLC via BOOTP-DHCP, but discovery doesn't find it.
So, my colleague has connected a client laptop with all Rockwell s/w to the PLC with a USB cable. Windows Device Manager on the laptop shows the attached [WindowsDeviceManager] which looks like the connection isn't quite properly set up, and yet the model of PLC is identifiable ?
Factory Talk Linx Browser shows a network connection node for "USB" but, whilst the three little LEDs on that USB icon blink, no attached device is found.
In RS Linx Classic, I do RS Who, but I don't get the "USB" node appearing in the tree of drivers which the 1769 installation manual promises I will.
Any thoughts if following up on this USB line of attack will prove useful in resetting the PLC, or does it look like a fatal problem ? What should Windows Device Manager be showing, and is there a driver upgrade available ?
Thanks all.
