Chapter 1: Getting Started
Step 7: Establish PC to PLC communications (cont'd)
Configuring the USB or RS-232 Serial Connection
Once we have a
communications cable
connected between a
port on the PC and
either the USB port
or PORT2 on the
CLICK PLUS PLC,
we need to select the PC COM port that is connected to the PLC. From the PLC ribbon, 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 PLC.
You do not need to change any of the parameters, just
click the Connect button. The software should start to
immediately connect to the PLC.
If you cannot connect the software to the CLICK PLUS
PLC, try the above procedure one more time and keep
watching the TX and RX indicators on the unit if using the
RS-232 port.
If the RX 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.
NOTE: If you are not sure to which PC COM Port the USB port is assigned, click the Detail button next to the COM
Port drop down list to identify it. Select it and click OK.
Proceed to page 1-29.
