Appendix A
LED Diagnostics For Communications Between QuickServer And Devices
A-3
-
Check baud rate, parity, data bits, stop bits
-
Check device address
-
Verify wiring
-
Verify device is connected to the same subnet as the QuickServer
-
Verify the Modbus device was discovered in Web Configurator (See “Connecting to QuickServer Web
Configurator” on page 13.).
• Field COM problems:
-
If Ethernet protocols are used, observe Ethernet LEDs on the QuickServer (See “LED Diagnostics For
Communications Between QuickServer And Devices” below).
-
Check DIP switch settings (using correct baud rate and device instance)
-
Verify IP Address setting
-
Verify wiring
If the problem persists, a Diagnostic Capture needs to be taken and sent to support. (See “Take Diag-
nostic Capture With The FieldServer Toolbox” on page A-4.).

LED
Description
SPL
The SPL LED will light if the unit is not getting a response from one or more of the configured devices.
RUN
The RUN LED will start flashing 20 seconds after power indicating normal operation.
ERR
The SYS ERR LED will go on solid 15 seconds after power up. It will turn off after 5 seconds. A steady red
light will indicate there is a system error on the unit. If this occurs, immediately report the related “system
error” shown in the error screen of the GUI interface to support for evaluation.
RX
The RX LED will flash when a message is received on the serial port on the 6-pin connector. If the serial
port is not used, this LED is non-operational.
TX
The TX LED will flash when a message is sent on the serial port on the 6-pin connector. If the serial port is
not used, this LED is non-operational.
PWR
This is the power light and should show steady green at all times when unit is powered.
