Description
1C31122G01 I/O Interface Module
The connection between 1C31122G01 and the industrial production process is realised through the i/o interface module. plc has many i/o interface modules, including switch input module, switch output module, analogue input module, analogue output module, and some other special modules, which should be selected according to their characteristics when used.
1C31122G01 Determine the number of i/o points. Different control objects require different numbers of i/o points, some typical transmission equipment and commonly used electrical components required plc i/o points are fixed, such as a single-coil solenoid valve with 2 input points, an output point; a pushbutton needs an input point; a signal lamp occupies an output point, etc., but for the same control object.
1C31122G01 adopts different control methods or different programming levels, the number of i/o points should also be different. According to the requirements of the control system to determine the number of i/o points required, should be increased by 10% to 20% of the spare amount, in order to increase the control function at any time.
