Appendix 9.2
Transmission from the external device to a CPU
module through the Ethernet adapter module
(1) Calculation formula
Tsf = Ke + (Kdt
Df) + 2
LS + Scr
Number of CPU module's sequence scans required for processing of the
m ACK processing time of external device [ms]
• 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
*1
For processing time on CC-Link IE Field Network, refer to the following.
User's manual for the master/local module used
*2
For sequence scan time of the CPU module, refer to the following.
