3 steps to choose the right PLC
How to choose the right PLC for your application maybe a question which may puzzle you for a long time. In fact, I'm also a member of "decidophobia", but don't worry, today GCAN will help you to choose the right PLC in 3 steps.
1. Reasonable structure is the 1 step to choose the right PLC
The average price of each I/O point of the integrated PLC is cheaper than that of the modular type, and the volume is relatively small, so it is generally used in a small control system with a relatively fixed system process.
The modular PLC has flexible and convenient functions and also has a large margin of choice in the number of I/O points, the ratio of the number of input points to the number of output points, and the type of I/O modules. It is also convenient to judge the scope of the fault by simply replacing the module during maintenance. Therefore, modular PLCs are generally suitable for applications where the complexity of the system and the environment is poor (large maintenance).
The suitable structure is the basic to choose the right PLC. Here, I have to introduce you GCAN-PLC, which is a modular PLC with compact size and competitive price.
2. Choice of installation method
The 2 step to choose the right PLC is installation, which is divided into centralized, remote I/O type and distributed distribution of multiple PLCs. Centralized does not need to set up to drive remote I / O hardware, system response is fast, low cost. Large systems often use remote I/O because they have a wide range of devices. The distribution of multiple networks is suitable for multiple devices to be independently controlled as well as mutual connection, a small PLC can be selected. ( GCAN-PLC has 3 communication interface in the CPU, there's no need to add extra communication module.)
3. Requirement of functions
The functions is the most important point to choose a right PLC. Generally, the small PLC has functions such as logic operation, timing, counting, etc., and can be satisfied for devices that only require switching control. For some complex control system, large PLCs with analog IO modules are need.
GCAN-PLC has both DI, DO and AI, AO modules such as 4-20mA IO, PT100, PWM, and -10-10V IO, etc. You should choose the right PLC according to the functions you need.
I believe you have already know how to choose the right PLC with the above 3 steps. There is also another factor you may notice: the scanning cycle, and high scanning speed PLC could decrease the response latency.
