Appendix 9.2
Transmission from the external device to a CPU 
module through the Ethernet adapter module
(1) Calculation formula
Tsf = Ke + (Kdt x Df) + 2 × LS + Scr × Number of CPU module's sequence scans required for processing of the 
message + ACK processing time of external device [ms]
*1
For processing time on CC-Link IE Field Network, refer to the following.
 User's manual of the master/local module used
*2
For sequence scan time of the CPU module, refer to the following.
 User's manual of the CPU module used (Function Explanation, Program Fundamentals)
 • Constant (Ke, Kdt)
Tsf
:
The elapsed time between when the Ethernet adapter module receives request data from the external device 
and when until the requested processing is completed
Ke, Kdt
:
Constant
Df
:
Number of words in request message (excluding the header) + Number of words in response message 
(excluding the header)
LS
*1
:
Link scan time of CC-Link IE Field Network
Scr
*2
:
Sequence scan time of CPU module
