[Calculation example 1]
Calculate the time the FX
3U
-ENET takes to complete the processing of
a data request from a PC after receiving it, when the FX
3U
-ENETand
the PC perform TCP/IP communication and read 32 points of ASCII
code data from the data register (D) of the local station (unit: ms) using
MC protocol communication.
• Assume that the scan time of the FX
3U
-ENET installed station is 40
ms:
59.17 + ACK processing time of the external device (ms)

1 + ACK processing time of the
external device
Command data length = 12 words
Response data length = 66 words
