Chapter 1: Getting Started
Step 6: Establish PC to PLC communications (cont'd)
Once we have a communications cable connected between
a port on the PC and PORT1 on the CLICK PLC, we
need to select the PC COM port that is connected to the
CLICK PLC. From the PLC drop down menu, select
Connect as shown to the right, or click on the Connect
icon (left) located on the PLC Toolbar.
The Connect to PLC dialog box will be displayed.
Under the COM Port No.: drop down list, select the
communications port that is connected to the CLICK
PLC Port 1.
If you are connecting the programming cable to Port 1 on
the CLICK PLC unit, you do not need to change any of the
parameters, just click the Connect button. The software
should start to immediately connect to the CLICK PLC.
If you cannot connect the software to the CLICK PLC, try
the above procedure one more time and keep watching the
TX1 and RX1 indicators on the CLICK PLC unit.
If the RX1 is not blinking, it means the CLICK PLC unit
is not receiving any data from the programming software.
Check to make sure you have selected the correct PC COM
Port, and also check the cable connections.
