Simply put, PLC is a programmable logic controller, the most used, the simplest way of programming is the ladder diagram, so even if you don't have a program that can be. PLC function can replace traditional relay realize automatic control. More knowledge, I suggest you look at this Web site, you will be rewarding.
Learn PLC programming what equipment will I need
If you want to learn PLC programming, I suggest you buy a PLC can be used, or domestic plc are relatively cheap, and need to have a computer, preferably XP system, because a lot of incompatible software and the latest system, first you learn from Mitsubishi's start, is relatively simple. Download video tutorial from the … Continue reading Learn PLC programming what equipment will I need

PLC what difference does digital and analog
Digital transmission is digital, such as traffic signals; is a voltage or current value of analog transmission; 4 to 20mA current signal input, analog input, then convert it into digital signals, the digital calculating and processing
PLC connection relay
Can both control and manual control, auto/manual transfer switch should be added, in case of contradiction between automatic and manual control, and automatic/manual transfer switch, then you can completely from the PLC, relay direct control of solenoid valves achieve the purpose of manual
PLC applications what are the main
1 for switch controlPLC control switching capability is strong. Under the control of the in and out points, more than 10 points less, dozens of points, many hundreds of, thousands of and even tens of thousands of points. Due to its network, virtually unlimited points, no matter how many points can control.The logical problems can … Continue reading PLC applications what are the main
PLC selection guide
First, input/output (I/O) point estimateI/O points should be considered when estimating the appropriate margins, usually according to the statistics of the input and output points, adding 10%~20% and ExtensibleAfter allowance, as input and output point estimates. Actual orders, according to manufacturer product features of the PLC, the input and output points are rounded.Second, the storage … Continue reading PLC selection guide
