14.1 Online Monitoring Function<br />

14.1.1 Changing the Operating Status of a PLC<br />

<strong>User</strong>s need to constantly change the operating status of a PLC when they test and debug the<br />

program in the PLC. They can easily change the status of the PLC by means of <strong>ISPSoft</strong>. Before the<br />

operation status of a PLC is changed by means of <strong>ISPSoft</strong>, users have to make sure that <strong>ISPSoft</strong> is<br />

connected to the PLC normally. Please refer to section 2.4 for more information.<br />

After users click Run on the PLC menu or on the toolbar, the PLC will begin to run. The PLC<br />

will stop running after Stop on the PLC menu or on the toolbar is clicked.<br />

If the operating status of a PLC is changed by means of <strong>ISPSoft</strong>, users do not have to consider the<br />

state of the RUN/STOP switch on the PLC. After the operating status of a PLC is changed by means<br />

of <strong>ISPSoft</strong>, users still can change the operating status of the PLC again by means of the RUN/STOP<br />

switch on the PLC.<br />

14.1.2 Online Monitoring Function and Environment<br />
