The Contact Inputs section is used to program the state of each contact input when in test
mode. The number of Contact Inputs available is dependent on the installed Order Code
options.
Contact Inputs setpoints here (in test) will revert to default values at power-up.
Path: Setpoints > Testing > Contact Inputs
CI 1(X):
Range: Off, On
Default: Off
The item name displays the user configurable name for the contact input.
The Output Relays section is used to program the state of each output relay when the
device is in test mode and Force Relays is "Enabled".
Select "Off" to force the output relay to the de-energized state, or select "On" to force the
output relay to the energized state.
The number of Output Relays available is dependent on the installed Order Code options.
Output Relays setpoints here (in test mode) will revert to default values at power-up.

This section specifies the Ethernet Loopback test function for Port 4 and Port 5.
The Ethernet Loopback test can only be initiated in Factory Service mode by using either
the Front Panel or a Modbus client. The user can specify the number of iterations for the
test and the status of the test. Pass and fail counters are made available through the Front
Panel and a Modbus client only when Factory Service mode is enabled (under
Device > Security ). The test transmits an alternating pattern to ensure the data is always
changing and checks if it is properly received. The user must provide an external loop-back
connection for each port during the test.
Path: Setpoints > Factory > Loopback Test > Port 4 (5)
NUMBER OF TESTS
Range: 0 to 65535 in steps of 1
Default: 500
This setting is used to enter the number of iterations of the loop-back test.
TEST START
Range: No, Yes
Default: No
This setting is used to initiate the test when the command is set to "Yes".
