9.3.2. Time Monitoring Function
This section describes the time monitoring function of the software part.
Time Monitoring Using Internal Timers of the Software Part

Assuming that processing has the executing status and does not end due to an error, the
software part uses its internal timers to interrupted the processing (i.e., timeout). The timeout is
set to 5 s (default) for each processing phase from open to close.

Time Monitoring Using the Ethernet Unit (Socket Services)

The Ethernet Unit has the time monitoring function as a socket service, which monitors the
arrival of receive data. This is set as a socket service parameter for receive processing. In the
software part, the parameter is named Receive Standby Time, which is set to 300 ms (default).
If receive data does not arrive from the code reader within this time, it judges that the receive
processing has ended.
Note
For information on time monitoring using socket services, refer to 6-7 Using Socket Services
by Manipulating Dedicated Control Bits in the CS/CJ-series Constructions of Applications
Operation Manual (Cat. No. W421).
Resending and Time Monitoring Using the Ethernet Unit (TCP/IP)

If a communications error occurs, TCP/IP automatically resends data and monitors the
processing time if there is no problem with the Ethernet Unit. If processing abnormally ends in
the middle of it, the software part stops the resending and time monitoring via TCP/IP in the
close processing. However, if the close processing shows a TCP connection status error, the
resending and time monitoring via TCP/IP may continue to be active in the Ethernet Unit. Refer
to 9.3.3. TCP Connection Status Error Situation and Correction for information on the error
situation and correction.
Resending and Time Monitoring via TCP/IP
* The number of seconds indicates the time elapsed since the first request after the occurrence of the error.
Monitoring description
Time from start to end of open processing
Time from start to end of send processing
* When "receive processing required" is set, the software part
checks the arrival of the first receive data to judge that the end of
processing.
Time from start to end of receive processing
* If receive processing is repeated, the software part monitors the
time for each repetition of receive processing.
Time from start to end of close processing
* The software part checks that the TCP connection status is normal
after close processing to judge the end of the processing.
