A
■Simple CPU communication function
The processing time of the simple CPU communication function (the increase in END processing time for the CPU module)
can be calculated by the following formula.
Processing time of the simple CPU communication function [s] = KM1 + T

[s] = KM2 + KM3  (number of bit points to be communicated  16 + number of word points to be communicated) +

[s] = KM4 + KM5  (number of bit points to be communicated  16 + number of word points to be communicated)
Device/label access service processing time
This section describes the device/label access service processing time when "Processing time = One time" in the device/label
access service processing setting.
*1 When data are written to the program using a pointer (P) during RUN, the processing time is extended depending on the pointer number
used. For example, when the data are written to the program using P8191 during RUN, the processing time is extended up to 3.0ms.
• T
n
: Simple CPU communication processing time per setting
• E
n
: Additional time when the file register (R, ZR) is used (It is added when the file register (R, ZR) is used.)
• n: Number of settings
