Table6.36 Processing times related to the high speed I/O refresh and high speed buffer transfer (continued)
Item Processing time
Buffer memory writing
Main base unit:
• 16 words or less ••• Time=0.47 (total number of transferred words)+2.65 (number of
settings)+0.95
• More than 16 words••• Time=0.55 (total number of transferred words)+0.95
Extension base unit:
• 16 words or less••• Time=1.07 (total number of transferred words)+2.65 (number of
settings)+0.95
• More than 16 words ••• Time=1.15 (total number of transferred words)+0.95
(Calculation example) When a main base unit is used, the number of settings is 1, and two words
are to be transferred, the time is 4.54 s.
Y output
Main base unit: Time=0.13 (total of Y points)+1.55
Extension base unit: Time=0.2 (total of Y points)+1.55
(Calculation example) When a main base unit is used, the number of settings is 1, and 16 points
are set for Y, the time is 3.63 s.
