9.3.2. Time Monitoring Function
This section explains the time monitoring function of this program. You can change the
monitoring time by changing the setting values in the program.
●Time monitoring function of the communication instruction processing
To avoid errors that keep a communications process executing without a stop, the timer in
this program is used to abort the processing (timeout). The timeout value for each
processing from the open processing to the close processing is 5 seconds (default).

●Receive wait function of the divided packets
The receive processing is repeated to receive divided packets for when receive data are
divided and arrive. 300 ms (default) is set as a parameter of the socket service at the
receive processing. Then, if the receive data does not arrive from the destination device
within this time at each receive processing (if the receive data arrive at an interval of more
than 300 ms), repeating the receive processing will end.
Additional Information
For information on the time monitoring function of the socket service, refer to 6-7 Using
Socket Services by Manipulating Dedicated Control Bits of the CJ-series Ethernet Units
