PING Command
When you are setting up or testing substation networks, it is helpful to
determine if the network is connected properly and if the other devices are
powered up and configured properly. The PING command (Access Level 2)
allows a user of the relay to determine if a host is reachable across an IP
network and/or if the Ethernet port (Port 1) is functioning or configured
correctly. A typical PING command response is shown in Figure 7.19.
The command structure is:
PING x.x.x.x t
where:
x.x.x.x is the Host IP address and
‘t’ is the PING interval in seconds, with a 2 to 255 second range.
The default PING interval is one second when ‘t’ is not specified. The relay
sends ping messages to the remote node until you stop the PING test by
pressing the ‘Q’ key.
PULSE Command
Use the PULSE command (see Table 7.36) to pulse any of the relay control
outputs for a specified time. This function aids you in relay testing and
commissioning. When a PUL command is issued, the selected contact will
close or open depending on the output contact type (a or b). The PUL
command energizes the coil and does not have any effect if the coil is already
energized. The control outputs are OUTnnn, where nnn represents 101–103
(standard), 301–304 (optional), 401–404 (optional), or 501–504 (optional).
