I/O Response Time in Tag Data Links
Note
(6) Output ON response time
This is the delay time for the external output device from when the output bit
turns ON in the memory of the CPU Unit until the output is actually performed.
In this system configuration, the delay time for an output relay is 2.0 ms. Also,
one CPU cycle time is required until the data is stored in the memory area of
the CPU Unit.
The maximum tag data link I/O response time for this system configuration
found from the total of (1) to (6) is 124 ms.
The I/O response time may be longer due to noise, or other events.

(5) Receive data process-
ing time
A CPU Unit cycle time of PLC #2
B Output relay delay time
Total:
(6) Node 2 (PLC #2) output ON response time
(1) Node 1 (PLC #1) input ON response time
(2) Node 1 (PLC #1) send data processing time
(3) Packet Interval (RPI)
(4) Network Transmission Delay Time
(5) Node 2 (PLC #2) receive data processing time
(6) Output ON response time
Maximum I/O response performance (total of (1) to (6))

A 10 m sec > C 6.15 m sec
To meet the condition to enable processing
in one data transmission, the number of
transmissions is the same as B plus 1.
