In the handheld programming device method, a proprietary device is connected to PLC through a connecting cable. These programming terminal devices include handheld and PC based devices. Various types of programming devices are used to enter, modify and troubleshoot a PLC program. These function blocks include timers, counters, strings, comparators, numeric, arithmetic, bit-shift, calling functions, and so on. All the necessary functions and functional blocks are available in the standard library of each PLC software. Some of the standard programming languages of PLC are basically of two types, which are further sub-divided into several types, which are as follows:Ĭompared with text based languages, graphical languages are preferred by many users to program a PLC due to their simple and convenient programming features. Some manufacturers have common programming languages and some others have dissimilar. But the PLC programming language is varied depending on the manufacturers.

Executing interrupts and handling errors.Specifying output signals to all binary and analog output signals.Reading and evaluating all binary and analog input signals.Initiating all the conditions for starting the specified task.Some of the tasks of the user program include: This must be created by the users and need to be downloaded to the CPU of the PLC. It is a combination of various functions which are required to process an automated task.
