Available Device Memory
The available setting range of device memory varies depending on the model. Be sure to set within the range available for the
model to be used. Use [TYPE] when assigning indirect device memory for macro programs.
Indirect Device Memory Designation
* In the expansion code, set which word, higher or lower, is to be read when a double-word address is specified
(expansion bit designation).
PLC_CTL
Macro command “PLC_CTL F0 F1 F2”
* Depends on the time set for [Time-out Time] under [Communication Setting] in the [PLC Properties] window ([System Setting]
[Hardware Setting]).
