DEVICE COMMUNICATION TROUBLESHOOTING
The following is a list of things to check, in order of
priority, if you are having problems connecting to
your controller from Pro-FX Control.
1. Make sure the device is powered up. You should
see a green light on LED A of the device. It
is okay if this is flashing (this just means the
controller is currently in run mode).
2. Make sure the USB port is connected and
Windows has properly loaded the drivers.
In the device manager you should see under
"Ports" an entry that say’s "Mobile Controller:
Enhanced COM Port".
3. Make sure that the gateway.cfg file has been
properly installed per the instructions in this
document. Installation of an alternate CODESYS
device gateway may have overwritten this file.
4. In the Pro-FX Control "Communication Settings",
select "None" for the "Filter". Then rescan for the
device. If something new shows up, then it could
be that the device variant being used by your
project is different than the connected device.
Pro-FX Control will only let you connect to a
device variant that matches the configuration of
your project. To switch to the appropriate device,
right click on it in the "Devices" project tree and
select "Update Device".
5. Stop and start the gateway. Plug and unplug the
USB port.
6. Restart Pro-FX Control.
7. Restart your PC
8. In some cases, Windows will automatically assign
a high COM port number to the USB device. If
the device manager shows something higher
than "COM20" then you should reassign it to
something lower. Then restart the gateway and
unplug and plug the USB port.
9. Each time a unique mobile controller is connected
to your PC, Windows will provide 2 new COM
port numbers. In some cases, Pro-FX Control
appears to have problems automatically
discovering the device's COM port when the
value gets too high. In this case there are 2
options:
•
From the device manager, click the COM port's
properties, select "Port Settings" tab, click
"Advanced", and select a "Com Port Number" that
is below COM20. Then restart the gateway and
replug the USB device to ensure changes are
applied properly.
•
You can alternately edit the gateway.cfg to
manually assign your device's COM port number.
Open the gateway.cfg file located in the directory
{ProgramFiles (x86)}\3S CODESYS\GatewayPLC
and change the line that begins with "Com.0.Port".
After making this change, restart the gateway.
Note: After making this change, your installation will no longer
automatically detect other controllers, so this must be repeated
for all unique controllers that are connected to your PC.

DEVICE RECOVERY
On HFX, short PWM1_2A *AND* PWM2_2A to
VBAT (must be > 11 V). Then power the system with
either the service tool running or attempt to connect
via CODESYS within 3 seconds after powerup. This
will prevent the CODESYS application from running
and then you can recover it.
