*1 Cannot be sampled when selecting "Safety Cycle Time" for "Sampling Method."
*2 When the number of device points is set to 512 points or less in the CPU parameter, the set number of points is sampled (the minimum
is 64 points (bits)).
*3 When the number of device points is set to 32 points or less in the CPU parameter, the set number of points is sampled (the minimum is
4 points (words)).
*4 Can be sampled only when using a safety CPU.
*5 Neither local index register nor local long index register can be specified.
When specifying either of them in a program, an index register or a long index register is sampled as a global device.
In addition, 32-bit index modification with ZZ expression cannot be specified.
*6 When using 'include SFC device' of 'device/label batch specification,' information for the system is also sampled for displaying a
program for monitoring in an SFC diagram on the offline monitor. (Page 40 When using 'include SFC device' of 'device/label batch
specification')
SFC block devices (BL) in a ladder program or Zoom can be monitored only when selecting the above method.

• When specifying an SA\T, a contact (SA\TS), coil (SA\TC),
and current value (SA\TN) are sampled.
• Even when specifying an SA\TS, SA\TC, or SA\TN
individually, all of them are sampled.
• When specifying an SA\ST, a contact (SA\STS), coil
(SA\STC), and current value (SA\STN) are sampled.
• Even when specifying an SA\STS, SA\STC, or SA\STN
individually, all of them are sampled.
• When specifying an SA\C, a contact (SA\CS), coil
(SA\CC), and current value (SA\CN) are sampled.
• Even when specifying an SA\CS, SA\CC, or SA\CN
individually, all of them are sampled.
