Communication Response Time
Time Frames of Communication Response Time
This section describes the communication time frames (T2 to T6).
The maximum time required is shown for each time frame. However, depending on the
actual environment, it may require more time.
■ T2 (DL-RS1A data processing time)
For information on the calculation function, refer to the manual supplied with the sensor amplifiers.
● When calculation function of sensor amplifiers is OFF *
* This table also applies to the sensor amplifiers that do not have the calculation function.
●
When calculation function of sensor amplifiers is ON
■ T3 (Command send time from external device)
Refer to the manual supplied with the external device connected to DL-RS1A.
