E-42 Application Examples
This rung simply gives the following rung a false-to-true transition every 1 second.
This rung copies up to 64 words beginning with N12:0 to the SCNR for transfer to the Basic module on ControlNet.
This rung completes the handshaking between the SLC processor and ultimately the Basic module to accomplish the CALL 23.

This rung copies up to 64 words of data received from the Basic module, when the handshake bit M1:3.3/9 becomes set. When data is
received by the Basic module in PRT2, the CALL 22 transfers it to the SCNR and ultimately to the SLC Processor.
