Appendix 3.3 Transmission Delay Time - Mitsubishi Electric NZ2GF-CCB User Manual

Appendix 3.3
This section describes transmission delay time between the CPU module of the master station and a remote station of
CC-Link when a bridge module is used.
(1) Between the master station and a CC-Link remote I/O station
(a) From a CC-Link remote I/O station to the master station (RX) (input)
The following shows the time it takes for a CPU module device of the master station to turn on (off) after a
signal is input to a CC-Link remote I/O station.
For CC-Link, station-based block data assurance is disabled and the asynchronous mode is used.
• CC-Link IE Field Network station-based block data assurance is available.
Calculated
Calculation formula for asynchronous mode
value
(SM  1) + (LSf  n1) + 
Normal value
(SM  1) + {LSf  (n1 + 1)} + 
Maximum value
• CC-Link IE Field Network station-based block data assurance is not available.
Calculated
Calculation formula for asynchronous mode
value
(SM  1) + (LSf  1) + 
Normal value
(SM  1) + (LSf  2) + 
Maximum value
SM: Sequence scan time of the master station (including the link refresh time of the receiving side)
LSf: Link scan time of CC-Link IE Field Network
n1: Value obtained by rounding up the decimal places of (SM  LSf)

: Time for data transfer from CC-Link to CC-Link IE Field Network
R
LSc: Link scan time of CC-Link
Rio: Processing time of a CC-Link remote I/O station ( Manual for the CC-Link remote I/O station used)
