How to optimize communication performance in NAPOPC_CE5
■We connect to I-87024/I-87017/I-87058/I-7024/I-7033/I-7041 via COM1 of WinPAC.Search all modules via COM1, and then we could get these modules in NAPOPC_CE5Server.
Click any one module, and we could see“Average Scan Time”on the status bar of NAPOPC_CE5window. Now Average Scan Time we get is 968 ms.
So far,the Access-Interval of Each module is 968 ms.
■If we intend to set the Access-Interval as below:
▲I-87024/I-7024: 1 Second
▲I-87058/I-7041: 3 Second
▲I-87017/I-7033: 100ms
●We could operate as following steps:
■Divide these modules into two different COM ports. Connect I-87024/I-87017/I-87058 to COM1, and connect I-7024/I-7033/I-7041 to COM2.
■Search modules via COM1/COM2 again, and then check “Average Scan Time”.
We will find “Average Scan time”has been getting faster.
■We could adjust“Pending Time”to enhance the performance of communication further. Enter the Controller Setting table to look for the “Pending Time”option.
●According to our requirement, change the “Pending Time”as following.
After we accomplish it, we could get better “Average Scan Time”as 62ms and 31ms.
Finally, we have improved Access-Interval and set different intervals for different modules.
