one of the following messages:
•Online - The Control Link ACC is communicating normally.
•Offline - The Control Link ACC is not communicating, has not been commissioned, is not functional, or is not powered up. Ver-
ify the Control Link ACC is powered up, wired correctly, and has the proper network address, baud rate, and parity (see
"Troubleshooting Control Link ACCs and the ECT MODBUS Network" on page 18).
•Unknown - The Control Link ACC is not communicating or has not been commissioned. Verify the Control Link ACC is pow-
ered up, wired correctly, and has the proper network address, baud rate, and parity (see "Troubleshooting Control Link
ACCs and the ECT MODBUS Network" on page 18).
•No Port - No port is set up in the E2 Serial Configuration Manager to be a MODBUS port. Follow the instructions in "Set Up
Network Ports," page 7.
•Wrong FW Rev - This message is likely caused by the Control Link ACC having a firmware version older than the minimum
revision required by E2 for communication. Replace the Control Link ACC with a new controller that has the latest version
of firmware on it.
