Appendix 5 Processing Time
The processing time of CC-Link IE Field Network Basic consists of the time components below.
Sequence scan time + Link scan time + Slave station response processing time = Transmission delay time
For scan time, refer to MELSEC iQ-F FX5 User's Manual (Application).
For slave station response processing time, refer to manual for the slave station used.
For transmission delay time, refer to Page 81 Transmission delay time.
Transmission delay time
A transmission delay time includes an input transmission delay time and an output transmission delay time.
Input transmission delay time
The input transmission delay time means the following.
• Time between when a signal (RX) is input to the slave station and when a device of the master station turns on or off
• Time between data (RWr) is input to the slave station and when the data is stored in a device of the master station
The formula for calculating the input transmission delay time (maximum) is shown below.
Output transmission delay time
The output transmission delay time means the following.
• Time between when a device of the master station turns on or off and when the output (RY) of the slave station turns on or
off
• Time between when data is set to a device of the master station and when the data (RWw) is output to the slave station
The formula for calculating the output transmission delay time (maximum) is shown below.
SM: Sequence scan time (ms)
Ls: Link scan time (ms)
SS: Processing time required for the slave station to reflect the input (ms) (Refer to the manual for the slave station used.)
