30.13.1 Starting and Ending the Logic Monitor

Logic monitoring begins when you turn on the first bit of the #L system variable (#L_LogicMonitor) using a switch part.
Turn off the first bit to display the screen before logic monitoring begins. Specify #L_LogicMonitor.X[1] for the address. The #L_LogicMonitor.X[0] is for monitoring addresses. The address monitoring screen appears when the system variable specification bit is turned on, such as during logic monitoring.

Using an instruction, turn on bits 0 (Address Monitor) and 1 (Logic Monitor) of #L system Variable (#L_LogicMonitor).

You cannot start up multiple monitors at the same time. When bits 0 and 1 are turned on at the same time, the address monitor for bit 0 is triggered. And bit 1, which turned ON at the same time, turns OFF.
Once the monitors have started up, it is easy to switch monitors. Bit 0 or bit 1 of the system variable (#L_LogicMonitor) will not turn on/off when switching monitors.
You can start up the logic monitor when the logic functions are not being used. The address monitor is started up when you start up the logic monitor.
You cannot start the logic monitor on AGP-3302B or AGP-3301. The address monitor is started up when you start up the logic monitor.
