• Have you used an Ethernet port on PCM3.1?
◦ The communication will NOT work if you use one of the
internal communication ports
on PSM3.1
.
• Is the power on for the connected equipment?
• Check the Ethernet cable bend radius.
• Plug into another Ethernet port.

3.5 Controller software update
3.5.1 Connecting to a controller with PICUS
To connect to a controller:
1. Connect an Ethernet cable to any Ethernet port on your computer.
2. Connect the other end of the Ethernet cable to port 3 on the controller's processor and communication module (PCM).
This hardware module is in slot 7 of the controller rack.
• Port 3 is the recommended port. You could use any PCM Ethernet port.
• DO NOT use the internal communication ports on the power supply module (PSM) in slot 1.
3. Launch PICUS from your local computer.
• PICUS automatically locates the controller(s) connected to the network.
4. Select the controller on the
Connect
screen.
5. Select a
user
and enter a
password
.
• If the
user
and
password
are correct, you are logged on to the controller.
See
PICUS
,
Default permissions
in the
Designer's handbook
for factory default user names and passwords.
