When the program is downloaded to the PLC after, you can use the “status“ function network operating and test procedures.
1. starting the program state
1, and in the process Editor window and shows you which programs you want to test and your network.
2,PLC on the RUN works, driver status monitoring changes to PLC data values. Methods are as follows:
Click ² ² “program status on/off“ button
or menu command “debug“ → “program status“ displays the status of each element in the ladder diagram. Enter the “status“ in the ladder diagram, using colored blocks that operation of the coil or contact closure. : Indicates 
that the contact is closed, 
that operation of the coil.
or menu command “debug“ → “program status“ displays the status of each element in the ladder diagram. Enter the “status“ in the ladder diagram, using colored blocks that operation of the coil or contact closure. : Indicates 
that the contact is closed, 
that operation of the coil.² ² using menu command “Tools“ → “options“ to open the window, you can choose to set the ladder diagram of function block in the size and the color of colored blocks, display and so on.
Ladder diagram in which all the components in a running state of continuous update transform the process of with program execution.
2. the program status is used to simulate the process conditions (read, forced, to lift the ban and the abolition of all forced)
Through the State of the program from the program editor to the operand writes or forcing the new numerical methods, you can simulate the process conditions
Click the “program“ button
to start the monitoring data, and enable debugging tools.
to start the monitoring data, and enable debugging tools.(1) the number of write operations:
² ² operand directly (do not click), and then use the right mouse button to click an operand, and from the pop-up menu, select “write“.
(2) a single operand:
Click directly on the operand (not command), and then from the “debug“ toolbar, click “force“ icon 
Directly with the right mouse button to click an operand (not orders), and from the pop-up menu, select “force“.
(3) a single action to lift the ban:
Click directly on the operand (not command), and then from the “debug“ toolbar, click “lift the ban“ icon.
Directly with the right mouse button to click an operand (not orders), and from the pop-up menu, select “lift the ban“.
(4) all mandatory values lift the ban:
from “debug“ toolbar, click “all force“ icon
.
.Forcing data to be read or written instruction immediately immediately specify I/O points, when the CPU enters the STOP State, the output will be to force the value, rather than the values set in the system.
Note: mandatory values in the program, the program each time you scan will be reset to the value of the operand, and the input/output conditions or other normally have an impact on operations unrelated to the program logic. Force may cause the program operation cannot be expected, could result in death or serious injury or equipment damage. Coercion is the debugger tool, not to compensate for the malfunction of the device mandatory. Use of coercion only qualified personnel. After the compulsory program, be sure to inform all persons authorized maintenance or debugging programs. In cases, when debugging a program without a load, you can use the forcing function.

3. identify force icons
Mandatory data will display an icon.
(1) the yellow lock icon indicates that the force: that which has been “unequivocal“ or direct push for the currently displayed value.
(2) grey faded locked icon indicates the implicit: this value has already been “hidden“ force, which does not directly address mandatory, but larger memory area into another clear force area. For example, if VW0 is shown forcing, VB0 VB1 was implied force, because they are contained in VW0.
(3) half a block icon indicates that a part of the force. For example, VB 1 is an explicit mandate, the VW0 were part of the force, because a byte of VB1 was mandatory.
