• Max. 37.5 s or more than 37.5 s instruction processing time
• Max. 40 s when MELSECNET/H, CC-Link or intelligent function modules are mounted on
extension base unit.
22 s
<Main base unit>
Time = 0.14 (total number of X points)+0.65
<Extension base unit>
Time = 0.21 (total number of X points)+0.65
(Calculation example) 3.74 s when the module is mounted on the main base unit, the number of
settings is 1, and the number of X points is 16
<Main base unit>
• 16 words or less
Time = 0.47 (total number of transferred words)+2.85
• More than 16 words
Time = 0.5 (total number of transferred words)+0.95
<Extension base unit>
• 16 words or less
Time = 1.07 (total number of transferred words)+2.85
• More than 16 words
Time = 1.1 (total number of transferred words)+0.95
(Calculation example) 4.74 s when the module is mounted on the main base unit, thenumber of
settings is 1, and the number of words is 2
41 s
Depends on the user-created interrupt program.
<Main base unit>
• 16 words or less
Time = 0.47 (total number of transferred words)+2.65
• 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
• More than 16 words
Time = 1.15 (total number of transferred words)+0.95
(Calculation example) 4.54 s when the module is mounted on the main base unit, the number of
settings is 1, and the number of words is 2
<Main base unit>
Time = 0.13 (total number of Y points) +1.55
<Extension base unit>
Time = 0.2 (total number of Y points)+1.55
(Calculation example) 3.63 s when the module is mounted on the main base unit, the number of
settings is 1, and the number of Y points is 16
