It requires 30 input and output points, 4 analog inputs, 2 pulse outputs, 1 high-speed counting, and can communicate with the touch screen.
For a distance of 30 meters, you can consider choosing CP1E-N40DT-D (the body has 24 inputs, 16 outputs, 2 pulse outputs, and 6 high-speed counts).
Expansion IO module CP1W-40EDT (24 inputs, 16 outputs).
Analog input module CP1W-AD041 (4 channels).
The communication distance of 30 meters can only be done by RS422 485.
Option board model CP1W-CIF11.
1. PLC manufacturers
To determine the manufacturer of PLC, the requirements of equipment users, the designer's familiarity and design Xi with PLC of different manufacturers, the consistency of supporting products and technical services should be considered. From the perspective of the reliability of the PLC itself, in principle, as long as it is the product of a large foreign company, there should not be a problem of poor reliability.
Personally, I think that, generally speaking, for the occasion of controlling independent equipment or a simple control system, supporting Japanese PLC products has a certain advantage in terms of cost performance. For the distributed control system and remote IO system with high requirements for large-scale network communication function, the PLC produced in Europe and the United States has more advantages in network communication function. In addition, for some special industries (such as: metallurgy, tobacco, etc.), we should choose a mature and reliable PLC system that has been put into operation in related industries.
