PC vs PLC Control: Control System

There are two primary control systems employed in the area of industrial industrial automation solutions: PC-based controls and PLC (configurable logic controller)-based controls. In Malaysia, ASROCK Industrial PC Malaysia is reputable. While both controllers are widely used in a number of sectors, there are distinctions between the two control methods, which make PC-based control a preferable choice for some situations.

PC vs. PLC Control: What’s the Difference?

PLC controllers and PCs may automate certain machine tasks, whole processes, and even entire manufacturing lines. Timing, control, timing, and starting and halting motors, pumps, and valves are examples of these operations. Built-in or Snap-On I/O (input/output) is what distinguishes PLC control from PC-based control. Analog, digital, thermocouples, and other forms of I/O can be mixed in a PLC. While PC control systems contain similar sorts of IO, the IO is frequently dispersed across a deterministic network.

In order to fulfill activities like real – time monitoring (SCADA), SQL database administration, and IIoT, PLCs frequently need to be linked to other systems (usually PC-based). These software tools and network capabilities are frequently included into PC-based controllers.

What is Hardware and Software for Personal Computers (PC)

There are no shortages of new updates, goods, or technology to employ because IPCs (Industrial PCs) use the same software and hardware as hundreds of millions of other PCs across the world. IPCs are inexpensive, adaptable, and simple to integrate into a system. When the technology and software utilized in a system are so common, consumers may always expect to have cutting-edge computing capability at their fingertips. IPCs perform similarly to a typical office PC, making them easy to use and maintain.

IPCs can control non-real-time operations using Microsoft OS, Linux OS, and other operating systems, which implies the IPC can be used for more than only cyclic control tasks. In addition, IPCs may run both real-time and non-real-time operating systems. A Real-Time Operating System (RTOS) is a computer environment that responds to input in a predictable amount of time. Microseconds are commonly used to measure a real-time clock and turn-around reaction time. Ethernet (NIC) connectivity allows IPCs to easily connect to the company network.

The Maintenance and Costs on IPCs 

Because IPCs are not a niche market, their purchase and maintenance costs are often cheaper for a given processing speed or update rate. IPCs are also available in a variety of sizes and power levels, as well as with fanless or high-IP ratings (IP67 or higher). Maintenance and replacement may be a lot easier, and there are a lot of upgrade choices. An IPC from one manufacturer can frequently be replaced with an IPC from another company. When processing or computational power becomes a limiting issue, upgrades to the processor speed, memory (volatile and non-volatile), port choices, number of network interface cards (NICs), and other factors are frequently available.

Specified Goal

All controllers (including PLCs) and networks, such as EtherCAT, Ethernet/IP, Modbus TCP/IP, and others, can be used with IPCs. This makes it possible to create a more simplified, adaptable, and scalable control architecture.
