BE1-CDS220 Input And Output Functions 3-13
Pulsing an Output Contact
Outputs can be pulsed to provide the push-to-energize function provided in Basler Electric solid state
relays. This is useful in trip testing the protection and control system. When pulsed, the contact changes
from the current state as determined by the virtual output logic expression to the opposite state for 200
milliseconds. After 200 milliseconds, the output contact is returned automatically to logic control.
Pulse override control can be accessed from the HMI using screen 2.4, \CTRL\OUT and entering a P in
the field for the output contact. Control can be accessed from the ASCII command interface using the
CS/CO-OUTn=P (control select/control operate-output contact n=pulse) command.
Holding an Output Contact Open or Closed
An output can be forced to a closed (logic one or TRUE) state or to an open (logic zero or FALSE) state.
This is useful in testing to disable a contact during testing. Open or close logic override control can be
accessed from the HMI using screen 2.4, \CTRL\OUT and entering a one for closed or a zero for open in
the field for the output contact. Control can be accessed from the ASCII command interface using the
CS/CO-OUTn=0/1 (control select/control operate-output contact n=0/1) command.
Returning An Output Contact To Logic Control
When the logic has been overridden and the contact is held in an open or closed state, it is necessary to
return the contact to logic control manually.
Return to logic control can be accessed from the HMI using screen 2.4, \CTRL\OUT and entering an L for
return to logic control in the field for the output contact. Control can be accessed from the ASCII
command interface using the CS/CO-OUTn=L (control select/control operate-output contact n=logic
control) command.
CS/CO-OUT Command
Purpose:
Control Output status
Syntax: CS/CO-OUT[n][=<mode>/ENA/DIS]
Comments: n = Output number A/1/2/3/4/5/6.
mode=1/0/P/L
The output control commands require the use of Select Before Operate logic. First, the command must be
selected using the CS-OUT command. After the command is selected, there is a 30-second window
during which the CO-OUT control command can be entered. The control selected and operation selected
must exactly match or the command is blocked. If the command is not entered within the 30-second
window, the command is blocked. If the control command is blocked, an error message is output.
Output control commands, except for ENA and DIS, are acted on immediately. To take effect, the ENA or
DIS output control command changes must be saved with the EXIT command. The output control status
is saved to non-volatile memory, and if power is lost, it is restored after power returns.
Example 1. Enable output control feature.
>CS-OUT = ENA
OUT=ENA SELECTED
>CO-OUT = ENA
OUT=ENA EXECUTED
(Note: This is not effective until EXIT with SAVE (Y).)
Example 2. Test all outputs by pulsing momentarily.
CS-OUT = P
OUT=P SELECTED
CO-OUT = P
OUT=P EXECUTED
Example 3. Disable the trip output (1) by holding at 0.
CS-OUT1 = 0
OUT1=0 SELECTED
CO-OUT1 = 0
OUT1=0 EXECUTED
