PLC programming is a logical procedure In a PLC program, "things" (inputs and rungs) are either TRUE or FALSE If the proper input conditions are TRUE: The rung becomes TRUE and an output action occurs (for example, a motor turns on) If the proper input conditions are not TRUE: The rung becomes FALSE and an output action does not occur. PLC is the combination of both Hardware and Software. An input device is any peripheral piece of hardware that is used to send data information and control signals to any information processing system, in this case the PLC. Local Control and System Applications—Send analog and digital input data to a central communications system, and receive and execute control commands. Latching in a PLC requires at least one input to set the latch (Input A), one input to reset the latch (Input B) and one output to store the latch state (Output Y). You will be able to learn how to use the automatic control systems utilized in the industry with just your PC, the PLC programming software and an input/output interface (optional). Medium AC voltages (115 V) b. For distributed applications, we offer in-cabinet (IP20) and hardened on-machine (IP67/69K) options, in both modular and block designs. A PLC is typically housed in a metal enclosure.
