Switch Control Setup
Test By
The test duration mode can be selected: By Time—the amount of time it will run, or
By Message—the total number of messages it will send. (Default: By Time)
Time Duration
When the Test By Time option is selected, the Time Duration eld sets the number of
hours the test will be run. (Range: 1-23; Step: 1; Default: 1)
Message Duration
When the Test by Message option is selected, the Message Duration eld will set the
number of messages that will be sent. (Range: 100-1,000; Step: 100; Default: 100)
Repeat
This is the retest schedule interval: None, Daily, Weekly, or Monthly. (Default: Daily)
Time Between Messages
This is the number of seconds between each message transmission. The rst test message
is sent to each node sequentially. Then the second test message is sent to each node
sequentially, etc. (Range: 1-120; Step: 1; Default: 5)
Next Start Time
This eld is blank until the rst start time is entered. After the next test, the eld updates
automatically to show the next time a test will start. The Next Start Time function is
determined by the previous start time (entered manually or updated automatically from
the last test) and the congured Repeat interval. Note: Users are not allowed to set a
date or time in the past.
Link Keep Alive Test Section
When a TCP or UDP connection remains idle, it may shut down. A Link Keep Alive
command is not a test, but to keep all links active it periodically sends a single message
to every node. If more than one message is congured for the Scheduled Test, the Link
Keep Alive command only sends the rst congured message. It also records statistics
for the message transmissions.
Frequency
This sets how often a Link Keep Alive command is run. (Range: 1-60 minutes; Step: 1
minute; Default: 4 minutes)
Ping and Serial Link Test Section
A ping test is a manually sent Ethernet ping to a specic IP address. A serial link test is
a manually sent ping over a serial port to a specic DNP address.
Ping Test Timeout
If a ping test return takes longer than this configured value, the Ping Test event will
timeout and stop waiting for a response. Set this value in milliseconds. (Range: 500-5,000;
Step: 500; Default: 5,000)
Serial Link Test Timeout
If a serial link test return takes longer than this configured value, the Serial Link Test
event will timeout and stop waiting for a response. Set this value in milliseconds. (Range:
500-30,000; Step: 500; Default: 5,000)
Data Types Section
This section congures each message sent in a scheduled test. The Predened Data
Types messages sent are not actual coach or runner messages, but they’re congured
to represent the approximate size of an actual average coach or runner message. The
Denable Data Types allow users to dene their own messages by setting the byte size
of the sent and received messages.
