Step 4: Transmit the RG-STAT command to the relay or use HMI Screen 1.4.1 to verify the status of
input 1. Transmit the RS-NEW=0 command to the relay. From the actual field device, close (or
open) the specific contact that supplies relay Input 1. While maintaining contact position, verify
that Input 1 has changed state by transmitting the RG-STAT command or using HMI Screen
1.4.1. Return the field contact to its original state, verifying that Input 1 returns to its original
state. Transmit the RS-NEW command to the relay and review the event record associated with
the field contact change.
Step 5: Repeat Step 4 for each connected input.
Output Contacts
Purpose: To verify output contact settings and output contact logic settings.
Reference Commands: SN-VO, SL-VO, SG-HOLD
Step 1: Transmit the SN-VOA command to verify the Virtual Output A user-defined name, TRUE label,
and FALSE label.
Step 2: Repeat Step 1 for Virtual Outputs 1 through 15. Add the number of an output to the SN-VO
command to check that output's name and labels.
Step 3: Transmit the SL-VO command to obtain a list of all virtual outputs and their Boolean logic
equations. Verify that the desired virtual output equations match the reported equations.
Step 4: Verify the programmable hold timer setting for each hardware output by transmitting the
command SG-HOLD. The output hold timer setting for each output is reported as enabled (1) or
disabled (0).
Step 5: Verify the output contact activity by viewing the sequence of events reports with the RS-###
command.
Step 6: Use the procedure outlined under "Acceptance Tests, Control Outputs" to actuate selected
output contacts (V01 through V05) and actually trip or close the connected field device (circuit
breaker, lockout, etc.). Use the same procedure to verify that operation of the alarm output relay
(V0A) initiates the appropriate alarm response.
Virtual Selector Switches (If not used, skip to Virtual Control Switch)
Purpose: To verify the operation, labels, and logic settings of the 43 switches.
Reference Commands: SN-43, SL-43, RG-STAT, CS/CO-43
Step 1: Transmit the SN-43 command to verify the Virtual Selector Switch 43 name, TRUE label, and
FALSE label. This information is reported using the format SN-x43=name,TRUE label,FALSE
label.
Step 2: Repeat Step 1 for Virtual Selector Switches 143 through 343.
Step 3: Use the SL-x43 command to obtain the logic setting of Virtual Switches 43, through 343. Logic
settings for virtual switches can also be obtained by using the SL command or by viewing
optional HMI Screens \CTRL\43\43 through \CTRL\43\343. Verify that the desired virtual
selector switch setting matches the reported setting.
Step 4: Transmit the RG-STAT command to obtain the position of the four virtual selector switches.
Alternately, the virtual selector switch positions can be obtained through the optional HMI
Screens \CTRL\43\43 through \CTRL\43\343.
Step 5: Obtain write access to the relay by using the ACCESS= command. For each virtual selector
switch enabled in your logic scheme, change the switch position by entering CS-x43 = 1
(TRUE), 0 (FALSE), or P (Pulse) followed by CO-x43=1,0 or P. The syntax of the CS-x43 and
CO-x43 commands must match or the CO-x43 command won't be executed.
Step 6: Verify each switch position change by using the CO-x43 command or through optional HMI
Screens \CTRL\43\43 through \CTRL\43\343.
Step 7: Return each virtual selector switch to the original position.
Step 8: Verify the 43 Switch activities by viewing the sequence of events reports with the RS-###
command.
