&Ningbo Hongde Training Center Learning Process: Part One: Small Series
, /Wiring
, Input Wiring
Including button input wiring, type proximity or photoelectric switch wiring, type proximity or photoelectric switch wiring .
, Output wiring
Including relay output type wiring, transistor type output wiring, transistor type output wiring. At the same time, conduct wiring according to different types of loads, such as lights, relays, servo, etc.
Mainly understand the differences between several different output types and pay attention to wiring. (The basic skills of wiring are current conduction method and voltage adaptation to the load)
, hands-on practice
Connect the buttons and relays. Realize single button start and stop.
, simple programming
, familiar with the basic operations of the software
Including: R software burning, installation, opening programming software, creating a new project, saving the project, opening the project, and online, simulation, monitoring/address , create new tasks, create new segments, create new/tables, set parameters, etc.
, Understand the small/distribution and expansion
Including: //H the/distribution of three series of ontology and the/distribution of three series of expansion modules. Understand external input and output, memory allocation (the functions and differences of each part of the memory area).
, Familiar with basic instructions
Including: //R/////R and other instructions.
, Learn simple operations (such as downloading programs above)
Including: understanding the functions and settings of DIP switches, downloading programs on B, downloading programs on serial ports, etc.
, familiarity and selection of hardware.
Including: Familiar with the characteristics and differences of various small series and models. They include features, extensions, etc.
, Master some basic functions of small-sized devices
, Pulse control function (key to master)
Including: understanding the principle of pulse control, the difference between / and pulse plus direction control, continuous mode and independent mode The difference, the role of origin search, the difference between relative and absolute. Learn functions such as jog, stop, relative position forward and reverse, origin search (familiar with the differences and settings of several different methods of origin search), absolute position forward and reverse, automatic reciprocating movement, etc. Master the use of D//// and other instructions through the above functions.
, Serial communication function (key to master)
Including: serial communication principle, wiring, port definition. Connect with the touch screen, connect with the computer, connect with the thermostat/inverter, etc., and connect with third-party equipment. Based on the above connections, master communication methods such as //serial gateway/R (no protocol). Learn how to make cables when communicating with different devices.
, Ethernet communication functions (key to master)
Including: Ethernet communication principles, the role and setting of addresses, understanding the difference from D mode, understanding the role of routing tables, and learning to make routing tables. Master the use of Ethernet modules such as, , and etc., and understand the communication and data sharing functions of R instructions.
, High count function
Including: wiring, the principle and use of rotary encoder, high count setting, the principle and use of several different ways of high count, high count interrupt function, Comparison table login comparison and more.
, Analog functions
Including: understanding digital-to-analog conversion and analog-to-digital conversion, average function, peak function and valley function, etc. Know the difference between current and voltage, know how to connect wires, etc.
, Interrupt function
Including: interrupt principle and function. Distinguish between scheduled interrupts, external/interrupts, high count interrupts, and input interrupts.
Part 2: Medium Series
, understanding and hardware composition of various modules
