Software Switch Descriptions
The Software Switches function as described in the following table.
*1 The Software Switches will also be initialized at the following times: when the Controller is reset, when the
operating mode is changed between PROGRAM and RUN Modes, when the Unit is restarted, or when the
communications port is restarted.
After the variable is set, the Software Switch will be reset (cleared) at the timing indicated in "Reset" in the
above table for each area.
*2 If both of the trace switches for one-shot trace and continuous trace are changed to TRUE, the one for which
the switch was changed first is executed. (The other one does not start until its trace switch changes to FALSE
and then back to TRUE after another trace operation is completed.) If both of the switches change to TRUE
simultaneously, the Continuous Trace will take priority.
When the trace buffer becomes full, the Unit will clear it.
The CPU Unit will manipulate the One-shot Trace Switch and Continuous Trace Switch when trace operations
are performed from the CX-Protocol. Do not manipulate these switches from a user program.
