Troubleshooting guide

Problem: ABB IP Configuration Tool does not find any SREA-01 units

• Some firewall applications block the ABB IP Configuration Tool. If you are

experiencing problems with finding the SREA-01 unit, try disabling your firewall.

• Make sure that SREA-01 is connected to the same network as the PC without any

gateways.

• Try using a crossover Ethernet cable and connecting the PC to SREA-01 directly.

Problem: SREA-01 can not be connected to locally

• Check that the link LED of the SREA-01 unit is lit. If necessary, check the

Ethernet cabling. Use a straight Ethernet cable when using a switch and a

crossover Ethernet cable when connecting directly to a PC.

• Make sure that SREA-01 is configured with correct network settings. Try

connecting to it with a crossover Ethernet cable and make sure that your network

adapter is configured to the same subnet as the SREA-01 unit. Check that the

unit can be found by ABB IP Configuration Tool.

• If you are using DHCP, make sure that the IP address of SREA-01 has not

changed automatically.

• Make sure that your browser is not configured to use a proxy server for local

network connections.

Problem: SREA-01 can not be connected to from a remote location

• Make sure that your internet service provider or network system does not block

port 80 from outside. If necessary, configure the SREA-01 to use an alternate web

server port (see section Webserver on page 75) and your firewall to allow traffic to

that port.

• If you are using DHCP, make sure that the IP address of SREA-01 has not

changed automatically.

Problem: Logging in fails

• Make sure that caps lock is turned off.

• Make sure that JavaScript is enabled in your browser.

• Try using Internet Explorer 6 or newer or Mozilla Firefox.

Problem: The drives are not found by SREA-01 or appear as ‘disconnected’

• Check that you have selected the correct physical interface, baud rate and parity

on the Setup – Modbus page. Check that all drives are configured to use the

same baud rate and parity.

• Check the Status page to see if communication works partially or not at all. Check

cabling, terminating resistors and the correct wiring of A/B channels or RX/TX

signals, depending on your setup.

• Check that all drives have different node addresses.
