Link Refresh Time - Mitsubishi Electric MELSEC-Q Series User Manual

Appendix 4.4
This section describes link refresh time (extended time of the END process in the CPU module).
(1) Master station/local station
The link refresh time of a master station and local station are calculated as follows.
(a) In the remote net Ver.1 mode and remote net Ver.2 mode
[Formula]
RX+RY+SB

T:

Link refresh time

RX: Total number of remote input (RX) points refreshed in the master station/local station
RY: Total number of remote output (RY) points refreshed in the master station/local station
RWw: Total number of remote register (RWw) points refreshed in the master station/local station
RWr: Total number of remote register (RWr) points refreshed in the master station/local station
SB: Total number of link special relay (SB) points refreshed in the master station/local station
SW: Total number of link special register (SW) points refreshed in the master station/local station
E:
Time that file register (R, ZR) data on a memory card is transferred (only when used)

Add E only when refreshing the data to the memory card file register. Addition is not required when refreshing the data to
the standard RAM and extended SRAM cassette file registers.
