NB-Designer supports online test operation. The online test provides the result which is equivalent with
the operation executed after downloading to PT and it allows to test directly on PC. Using the online test
during debugging can save a lot of time taken by the repeated downloading. The online test is classified
into direct online test and indirect online test, which are described as follows:
Direct online test is a test method that directly connects the PLC with the serial port of PC to test the
operation. Obtaining the dynamic PLC data without need to connect the PT is its advantage but the
communication between the PC and the PLC can support only RS-232 communications. During
debugging of PLC with RS-485 port, the adaptor that can convert RS-232 to RS-485/422 must be used.
Note 1
The test time of direct online test is 15 minutes. When 15 minutes is exceeded, the following prompt infor-
mation “The test time is exceeded, please perform the test again.” will appear. Then, the window of the test
will be closed automatically.
2
The direct online test can be done only through the RS-232 communication method.
3
The wiring method of direct online test is the direct connection of the PLC programming cable with the
serial port of PC.
4
It does not support the direct connection with the PLC of Ethernet connection type.
5
It does not support the direct online test with the other PLC than that manufactured by OMRON.
After the screen data is compiled, press the
button, then the following dialog box will pop up:
Select the PT No. to be tested and the COM No. of PC to be connected to the PLC, then click the “Start”
button to start the direct online test.
