1. OVERVIEWModbus RTU is an open, serial (RS-232 or RS-485) protocol derived from the Master/Slave architecture. It is a widely accepted protocol due to its ease of use and reliability. Modbus RTU is widely used within Building Management Systems (BMS) and Industrial Automation Systems (IAS). This wide acceptance is due in large part to MODBUS RTU’s ease of use. MODBUS RTU messages are a simple 16-bit CRC (Cyclic-Redundant Checksum). The simplicity of these messages is to ensure reliability. Due to…
The best way to understand how these two specifications are related is to refer to the Open System Interconnection (OSI) model. The OSI model specifies a seven layer framework for implementing communication protocols, which is shown as follows from top to bottom: Application Layer Presentation Layer Session Layer Transport Layer Network Layer Data-Link Layer Physical Layer The CAN specification defines the Physical and Data-link layers of the communication system. The CAN specification was developed by Bosch (ISO 11898-1) and fully…
There are once again many terms in this sermon so grab the post for this episode so you can get more detail. VGA Introduced in 1987, the Video Graphics Array connector (or VGA) is the standard blue 15-pin connector we have all dealt with. It has also been called RGB, D-sub or “that blue cable”. The VGA cable supports resolutions from 640×400 to 2048×1536. With the right equipment, you might be able to pinch a little more res out but…
Modbus is a serial communications protocol originally published by Modicon (now Schneider Electric) in 1979 for use with its programmable logic controllers (PLCs). Simple and robust, it has since become a de facto standard communication protocol, and it is now a commonly available means of connecting industrial electronic devices. The main reasons for the use of Modbus in the industrial environment are: It has been developed with industrial applications in mind It is openly published and royalty-free It is easy…
Because of CAN's cascading feature,CAN'S data baud rate is tighly tied to the transmission distance,through 5 months lab testing,Buenoptic finally worked out the testig results to CAN's transmission distance by fiber optic cable and pair twisted copper cable on different baud rates: CAN Tansmission Distance: Baud Rate（bit） Copper Cable（m） Fiber Distance（m） Remarks 1Mbir/s 25m 45m Lab Condition 800Kbir/s 50m 90m Lab Condition 500Kbir/s 100m 180m Lab Condition 250Kbir/s 250m 450m Lab Condition 125Kbir/s 500m 900m Lab Condition 100Kbir/s 650m 1150m(1.15Km)…
Atomic ClockAn atomic clock is an extremely accurate timekeeping device regulated by the natural regular oscillations of an atom or molecule. An atomic clock powered by a hydrogen atom (maser) is accurate to 1 part in 2 quadrillion. A cesium atom powered clock has an error of about one second in one million years. GPS satellites carry multiple atomic clocks, regulated by these precise atomic vibrations, to ensure accuracy. The GPS Master Control Station uses cesium clocks and a hydrogen…
Bueno Electric,as a manufacturer of various fieldbus/ethernet/serial to fiber optic converters,in recent years is engaged in both products markting and fiber optic converter products' knowledge propaganda,which helps customers know better about the application of fiber optic converter products. Currently,the fiber optic converter products mainly include 3 link ways: Point to point: In telecommunications, a point-to-point connection refers to a communications connection between two nodes or endpoints. An example is a telephone call, in which one telephone is connected with one…
