In order to complete the control strategy, in order to replace the relay and enable the user to complete the ladder diagram of the control system similar to the relay circuit, a set of control algorithm function blocks (or subprograms), called the instruction system, is compiled, which is fixed in the memory ROM, and can be called by the user when compiling the application program. The instruction system can be roughly divided into two types, namely basic instruction and extended instruction. The instruction system of subdivided general PLC includes: basic instruction, timer/counter instruction, shift instruction, transfer instruction, comparison instruction, conversion instruction, BCD operation instruction, binary operation instruction, increment/decrement instruction, logic operation instruction, special operation instruction, etc. These instructions are mostly similar to assembly language. In addition, PLC also improves sufficient internal resources such as timers, counters, internal relays, registers and storage areas, which brings great convenience to programming.

Due to the differences in the instruction system and the different user requirements in the programming methods of PLC manufacturers’ products, in recent years, IEC has formulated the Windows-based programming language standard IEC61131-3 (the international standard IEC1131 for programmable controllers issued by IEC in 1993), which specifies five programming languages: instruction list (IL), ladder diagram (LD), sequential function diagram (SFC), function block diagram (FBD), and structured text (ST). This includes textual programming (IL, ST) and graphic programming (LD, FBD), while SFC can be used in both programming languages. IEC Technical Committee (TC65) has recently launched the IEC61499 project and expanded IEC61131-3. It is a standard for the architecture of modular distributed systems interconnected through communication networks, which will improve IEC61131-3. This is a standardized document that the programmable logic control device based on digital technology moves towards openness at a high level and is a major trend of PLC development.
