Introduction
The Programmable Logic Controller (PLC) is a powerful tool to generate triggers and software interrupts. A functional diagram of the PLC tool is shown in Fig. 7.4. The PLC tool is described in detail with many examples in the [PLC] manual which is included in the PFInstaller. The AB Trigger feature is not available on all camera revisions, see Appendix B for a list of available features.

Figure 7.4: PLC functional overview and trigger connections
The simpliest application of the PLC is to connect a PLC input to a PLC output. The connection of the ISO_IN0 input to the PLC_Q4 camera trigger is given as an example. The resulting configuration is shown in Section 7.10.2. 7.10 PLC
