Example

The Tc3_PJLink_Sample.zip contains a PLC program to illustrate the use of FB_PJLink. Different commands can be sent to a projector once communication has been successfully established.

Commissioning procedure: The input parameter sProjector must be adjusted to the IP address of the projector that is to be controlled. The input parameter sSecurityPW must match the PJLink password in the projector settings. (Optional: only when PJLink security authorization is enabled.) Set the input parameter bEnable to TRUE to establish communication with the projector.

Comments regarding the program code:

• Calling FB_PJLink in the pjlink method in the MAIN program:

• Once the connection to a projector has been successfully established, methods can be called in the MAIN program to send commands to the projector:

Example of the power-on command. The command is triggered by setting bPowerExecute.

• If the following error message is logged, the parameter sSecurityPW does not match the security password set for the projector.

Additional notes:

• The example can also be tested in conjunction with the PJLink test software ("TEST4CNT"), which is used to simulate a projector. The software is available for download from http://pjlink.jbmia.or.jp/english/.
• The TwinCAT Function TF6310 "TwinCAT TCP/IP" is required for this example.

The download contains a TwinCAT project and the compiled library "Tc3_PJLink". This library must first be installed via the library repository. (See PLC > Using libraries)

The integrated libraries "Tc2_TcpIp", "Tc3_Module" and "Tc2_Utilities" are required for using the PJLink implementation.
