What is PLC Link?
Programmable Logic Controllers (PLCs) are now an essential part of the automated control of production/logistics sites around the world, and the devices connected to and controlled by PLCs are becoming more diverse every year.
PLCs were developed as an alternative to the relay circuits typical of conventional controllers. They are a type of so-called miniature computer and, like other computers, use a microprocessor for the core parts and are similar in that they are software-controlled. PLCs can control the operation of equipment and machines according to a pre-defined programme, in a pre-defined sequence and under pre-defined conditions, and can also control position, speed and continuous quantity, as well as exchanging information between devices.
Benefits of implementation
Benefits of PLC links
- Writes to the designated memory in the PLC by simply setting the scanner.
- No RS-232C or LAN communication programme required
- Programmable only with the PLC knowledge you have always developed.
- No need to know scanner commands.
- Easy to check operation.
