Appendix 5 Differences In Cyclic Transmission Modes - Mitsubishi Electric CC-Link IE TSN User Manual

Appendix 5
This chapter describes differences in cyclic transmission modes of CC-Link IE Field Network. Refer to the information of each
mode to select the mode.
Description
■Normal mode
Cyclic and transient transmission are performed without losing their inherent speed performance.
This mode is suitable for a system that transmits large amounts of data for management, monitoring, and diagnostics by
transient processing, along with regular I/O control or analog control.
Use this mode for general application.
■High-speed mode
Cyclic transmission has a priority over transient transmission.
This mode is suitable for applications requiring lower cycle times such as I/O control, analog control, and digital I/O.
In this mode, the priority of transient transmission is lower and its processing speed is slower than in normal mode.
Differences in performance specifications
The following table indicates the differences in performance specifications of each mode.
Item
Maximum number of RWw send points per local station
Maximum number of transient transmissions per link scan
Setting method
The NZ2GN-GFB communication mode is set from the module parameter or remote buffer memory of NZ2GN-GFB.
■Setting using module parameters
Set from the "Communication mode" of Application settings (CC-Link IE Field Network). ( Page 49 Parameter
information)
■Setting using remote buffer memory
Set from 'Communication mode' (011AH). ( Page 210 Communication mode)
Setting status
The setting status of the communication mode can be checked with 'Mode status of own station' (3043H) of the remote buffer
memory. For details, refer to the following.
