Technology in the PLC

PLC has been developing the capabilities of simple form and transform the same price level ever. And the development of which will go on. What’s left to do and tons more or no less interesting question.

As a related technology. We conclude the development of PLC from the past to current and upcoming follows.

1) patterns of language use. Still can not say that it will not use the ladder diagram (Ladder Diagram), but the role of the function block (Function Block) is more or even a programming language (Instruction List), which will combine both possible. IEC61131 requirements or not.

2) The development of the ability of PLC to manage mobile devices that generate a lot more like a servo motor. Linear motors. Inverter. By either increasing the speed of mobile functionality to support fast and accurate. Development of special cards for specific actions. Software development or software package for ease of use. These things will become easier and more common in PLC new generations.

3) the support for a network which has become a standard already. Optimization with a reduced number of cables used in plant and machinery is a current push for network-level devices (Component network), such as DeviceNet, Componet, EtherCat the needs for communication of control and order. and management of production networks driven in control and command (Control network), such as Ethernet / IP Controller Link and so on.

4) speed development. Still significant. Response to changes in a timely manner of machinery, more and more intense. The high-speed machinery. Especially in response to a device Encoder, Interrupt input, High speed pulse, even high-speed analog channels.
