125720-01 3500/32 Transient Data Interface Module
125720-01 3500/32 controller hardware itself using a building block structure, the structure of each manufacturer’s products are similar. Japan’s Omron C200HE, for example, for the bus template frame structure, the basic frame (CPU motherboard) is equipped with a CPU template, the other slots are equipped with I/O templates; if the I/O templates are more than one, the CPU motherboard can be connected to the I/O expansion motherboard through the I/O expansion cable, on which the I/O template; another method is equipped with remote I/O slave, etc.. These all illustrate the PLC manufacturers will be the hardware components are developed to the user to facilitate the choice of users, configured into a PLC of varying sizes, and the openness of this hardware configuration for manufacturers, distributors (agents), system integrators, end users to bring a lot of convenience for the marketing supply chain to bring a lot of convenience, which is a major success story.
I/O templates within the 125720-01 3500/32, in addition to the general DI/DO, AD/DA templates, but also the development of a series of special functions of the I/O templates, which opens the way for the PLC used in a variety of industries, such as ASCII/BASIC templates for bar code recognition, PID templates for feedback control, high-speed counting templates for operation control, machining, single-axis position control templates, dual-axis position control templates, cam positioner templates, radio frequency identification interface templates, etc., which will have great development in the future. In addition, the input and output components, strong interference occasions, input and output isolation, ground isolation, etc. will be more perfect.
The CPU in 125720-01 3500/32 cooperates with the memory to complete the control function. It is different from the DCS system to deal with temperature, pressure, flow and other parameters of the system, using a fast circuit scanning cycle, generally 0.1 ~ 0.2 seconds, and even faster, the choice of 50 milliseconds or less elimination cycle. It is a digital sampling control system.
