tool using this function.
: Available, : Available with restrictions, × : Not available
*1 This includes a ladder monitor, device batch monitor, entry data monitor, entry ladder monitor and local device monitor.
*2 Availability depends on the version of the CPU module. ( Page 465, Appendix 2)
(1) Monitor request timing and displayed data
The CPU module processes monitor requests from a programming tool during END processing. For this reason,
the data in the CPU module at the time of END processing will be displayed in the programming tool.
(2) Monitor with monitor condition settings
By setting a monitor condition in a programming tool during debugging, the program operation status in the CPU
module can be monitored under the specified condition. Also, by setting a monitoring stop condition, a monitoring
status can be held under the specified condition.
(3) Local device monitor
If multiple programs are executed and local devices are used, data in local devices of each program can also be
monitored.
