7. How to set the environment for OPC Server
95
7.3 Time adjusting function with TC-net
When used TC-net100(JTNI PCI Express Card) or TC-net1G(JTGI), this chapter describes a
function of adjust date/time of OPC server at the date/time of TC-net system.
Do "Setting of time adjusting interval with TC-net" of 7.1 "How to set the environment for
OPC Server" beforehand, and please reboot OPC server.
(1) Time adjusting function
At intervals of the execution that specified in "Setting of time adjusting interval with TC-net"
of 7.1 "How to set the environment for OPC Server", begin to read the date/time from TC-net
system and adjust the date/time of OPC server.
About an execution interval, please refer to "Setting of time adjusting interval with TC-net" of
7.1 "How to set the environment for OPC Server".
(2) Time adjusting processing
When never set the date/time in TC-net system, date/time that has begun to read from a
TC-net system is wrong.
On this account, do not adjust the date/time of OPC Server when compare the date/time of
TC-net system and OPC Server, and there was a difference more than one month (longer from
31 days). In this case the following log is output to log file (TCnetScanCtrl.log)
Example) Year and month of TC-net are different from the Current time. PC [2012/02/15] /
TC-net [2034/01/01]
In addition, the time does not adjust the date/time of PC in case of 00:00 so that "day" does not
change as much as possible. But, in the case of execution interval specification for 1-24 hours,
adjust the date/time five minutes later.
Execution log of date/time adjusting does not output it whenever adjust the date/time. When
differences of the date/time of TC-net system and OPC Server are more than one minute,
output it in log file. Following log is output to log file (TCnetScanCtrl.log)
Example) TC-net Date/Time Adjust Execute. : 2012/02/15 11:10:00.319 -> 2012/02/15
11:11:05.238
Important: "Time adjusting function with TC-net" added in TC-net OPC Server V01.80
