“Response with error” refers to frames that were received, i.e., they were included in the
count of “Responses received”, The initiating node compares the test data of all re-
sponses to the current test data (which always varies from the preceding frame because
of the sequence number in the first byte position). Any received frame that does not
compare is counted as a Response with error. The most common cause of this indication
is that the <sch> parameter in the TEST command is set to too short an interval. This
should be avoided by increasing <sch>. Also, some manufacturers’ products, while re-
plying to the test command, do not return the data field; this will cause all their Re-
sponses received to also tally a Response with error.
“No Response” is computed as the difference between the number of test commands
sent by the initiating node minus the number of Responses received from the subject
node. This number of frames were “lost” either outbound from the initiator, inbound to
the initiator, or internally (e.g., lack of buffers) to either the initiator or responder.
REPP Command
The REPP command has the form:
REPP
This command causes the results of the PING command to be reported. The results may
be for a currently running PING or otherwise the most recent PING command. Ping re-
sults are maintained, and may be displayed until another ping command is started, or
until the Modify security level is exited.
A typical REPP command is shown below:
= repp
<<< Ping Results >>>
Command: ping 3.0.0.1 10 100 64
Sent = 10, Received = 10, No Timely Response = 0
Late/Stray Response = 0
Round-trip (ms) min/avg/max 0/1/10
RESTART Command
The RESTART command has the form:
RESTART
The RESTART command causes the Ethernet Interface to be restarted without causing
the software to be reloaded. It has the same effect as pressing the Restart pushbutton on
the front edge of the Ethernet Interface quickly (2-3 seconds). Any data transfer be-
tween the Series 90-70 PLC and the network at the time the RESTART command is en-
tered is permanently lost.
A typical RESTART command is shown below:
= restart
