Appendix A Response performance

A.1 Response performance of Task code communication
The following data is response time of request task code from peripherals.
Since response time depends on many other factors, please use these values as sample data for your system designing.
Table A.1 shows the response time of the monitor command of 120 words on one EH-ETH2 module.

*1) CPU is stop. When CPU is running, response is longer.
*2) Response time doesn't depend on communication speed (10/100M).
*3) "Number of ports" shows the number of ports communicated at the same time.
*4) Without ASR communication / With ASR communication
"With ASR communication" is the state that all ASR connections are sending 120 words and
are receiving 120 words.
*5) EH-CPU5** : "EH-CPU5**" means EH-CPU548 or EH-CPU516.
A.2 Response performance of ASR communication
The following data is response time of the ASR communication.
Since response time depends on many other factors, please use these values as sample data for your system designing.
Table A.2 shows the interval time of ASR event sending of 120 or 360 words and shows the interval time of ASR
receiving of 120 or 360 words.
