There are many things worth learning about the Integrated Wiring Specification. Here we will mainly introduce the Integrated Wiring Specification, including the Integrated Wiring Specification and the questions about the grounding, and hope to help you, I believe that you can learn more. In the control system, multiple inverters are controlled using the analog quantity of PLC. the characteristics of the inverter itself produce strong interference sign
Freemodbus port description ZZ, freemodbus port zz
1. Why port Freemodbus?
Why do we need to port Freemodbus? This question needs to be answered from two aspects. First, modbus is a very good application layer protocol, which is concise and relatively complete. For those who have not been familiar with modbus, we do not recommend porting freemodbus directly. We should patiently start with the modbus document and fully grasp all the resources around us, for example, the modbus part of the

Solutions to the inability of two tl-pa201 routers to communicate
After my investigation, found that routers can not communicate between the reasons may be: improper equipment settings, physical circuit instability, affected by certain electrical devices in the circuit, the specific procedures are as follows:
One, when the equipment found in the line of another device, the PLC lantern Festival is often bright, said already can communicate with each
Terminal:
The GPRS remote terminal consists of an intelligent controller and a GPRS module. First, sensors collect industrial field parameters, and intelligent controllers analyze and process the collected data. On the one hand, they are displayed on the site, and on the other hand, they are sent to the GPRS module to control the operations of the GPRS module, this includes starting and disabling services, establishing and closing connections, converting data and command modes, and sending

[It168] Choosing a suitable broadband line makes your own Broadband Router even more powerful. Currently, common wide-line channels include XDSL, CM, fttx + LAN, PLC, DDN, satellite access, and microwave communication. Which of the following broadband access methods is better?
XDSL
XDSL refers to the digital user line access technology developed on telephone lines. Currently, it is commonly used in two types: ADSL and VDSL.① ADSL (Asymmetric Dig
interpret the Node Address, path, and troubleshooting methods.In other networks, controllers use peer-to-peer technology for communication, so any controller can initiate a communication with other controllers. In this way, the controller can act as either the master device or the slave device (slave) in a separate communication process ). Multiple internal channels can be used simultaneously by multiple transmission processes.While the network communication method is "peer-to-peer", the Modbus
also shared his profound insights on the way C works with me. As an ANSI and Iso c Standard editor, Dave provides a large number of electronic texts in this book. Hiroshi fukutomi and Takashi Kawahara, two principal directors of Tokyo's Senior Data Control Company (who took the lead in providing support for Chinese Characters in Japanese), learned about the technical needs of Japanese programmers, it helped me a lot.Most of the materials here have been posted on the C users journal.

Upper Machine
Refers to a person can directly issue control commands of the computer, generally PC, the screen shows a variety of signal changes (hydraulic, water level, temperature, etc.). The lower machine is the computer which directly controls the equipment to obtain the condition of the equipment, generally is the plc/single chip microcomputer and so on. The commands issued by the host computer are first given to the lower machine, and the subor
