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:

Example 2:

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 3: — 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.

Example 4:

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 https://infosys.beckhoff.com/content/1033/te1000_xae_overview/html/te1000_xae_intro.htm(PLC > Libraries).)

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