Frequently Asked Questions about DS200VPBLG2A
What are the power bugs that are within the DS200VPBLG2A board?
The ten power bugs that are on the DS200VPBLG2A board are used to electrically connect the VPBL model to the P1 backplane. All information regarding the power bugs can be found in table twenty-two of the GEI-100227 VME Backplane Board User's Guide.
What type of power connector does the DS200VPBLG2A board use?
The DS200VPBLG2A board uses JAA, a 12-pin Mate-n-Lock for power supply connection. Two of the nomenclatures are DCOMI and a digital common ground, that is isolated and ACOMI, which is a analog common ground, isolated.
How are the eight VME-type connectors in section J2 used on the DS200VPBLG2A board?
Six of the eight connectors are arranged with double-wide spacing and the spare two are single-spaced. The connectors are all used in many instances. For example, two of the J13 connectors, J13-A1, and J13-A1 are digital common grounds connections, for more information regarding the eight VME connectors please refer to the GEI-100227 VME Backplane Board User's Guide tables ten through seventeen for more extensive information.
Product Description
VME Backplane Board DS200VPBLG2A is part of the LS2100 Series produced by General Electric Industrial Systems. The model is the second version of the VPBL model. There are a number of sections within the VME Backplane, section J2 supports a number of boards within the LS2100 Series. The boards supported in section J2 are a DSPC, up to three Gate Distribution Status Boards, one exciter board, and an I/O extender daughterboard. The DS200VPBLG2A model has many input/output definitions, the specific definitions in the J2 section of the mode are the eight VME-type connectors, of the eight six are positioned with double-wide spacing, the two that are left over are single-spaced and allow for the opportunity for more capability enhancements. The DS200VPBLG2A model has a total of ten power bugs, the purpose of which is to electrically connect the P1 backplane to the VPBL. The model also has a thirty-four-pin ribbon connector, labeled as an EXJV. The purpose of the exciter connection is to handle all of the signals for the external exciter bridge.
A communication module is a hardware or software component that enables data transmission and communication between devices. It acts as a bridge between devices, allowing data to be passed and communicated between different devices. Communication modules play a vital role in modern communication systems, they can realize the transmission, reception and processing of data, but also provide a safe and stable communication environment. Function of communication module 1. Data transmission function: The communication module can realize data transmission between devices, including real-time data, audio, video and other different types of data. They transmit data from the source device to the target device through various communication protocols and technologies, such as wireless networks, Bluetooth, Ethernet, etc. 2. Data reception and processing function: The communication module can receive the data sent from other devices, and process and decode the data. They are able to identify and extract useful information, which is then passed on to the target device for further processing or display. 3. Security guarantee function: The communication module can provide security guarantee measures to ensure the safe transmission of data. They use encryption and authentication mechanisms to prevent illegal access and data leaks. 4. Network connection function: The communication module can establish a network connection between devices, so that devices can communicate and cooperate with each other. They can connect to different networks, such as local area networks, wide area networks, etc., to achieve remote control and management of devices.
1.1 Digital/analog signal difference The digital input/output signal is the switching signal, 1 or 0, Analog signals, there are two, voltage or current signals, generally the signal transmitted by the transmitter, such as the pressure transmitter to detect the pressure of the water pipe, it will output an analog signal 4-20mA or 0-10V signal to the PLC, PLC for data processing. The switching input point (DI) processes the switching input signal. Analog input point (AI), processing analog input signals (0-20mADC,0-5VDC). Resistance signal (including thermal resistance) input point, processing thermal resistance or general resistance signal. High-speed pulse input point, processing high-speed pulse signal. Voltage (including thermocouple) input point, processing voltage input or thermocouple signal. There is also communication, which is used to exchange data with the upper computer or control the instrument driver of the lower controller 1.2 Difference between digital and analog input modules According to the difference of field input signal, the input module can be divided into switching input module and analog input module. The function of the switching input module is to convert various switching signals into TTL standard signals required by the CPU. According to the input power supply type, it can be divided into DC input module and AC input module. The input signal is converted into TTL (5V) standard signal by photoelectric coupling after voltage division, current limiting and filtering. The function of the analog input module is to convert the continuously changing analog signals such as temperature, flow, current, voltage, etc. into several digital signals that the CPU can process. The analog input circuit is generally composed of op amp conversion, mode conversion (A/D), photoelectric isolation, etc. Types of PLC input and output modules: digital input DI, digital output DO, analog input AI, analog output AO. Digital input and output are generally 24V. There are 4 kinds of analog quantities in 2 categories, and the 2 categories are voltage type and current type respectively. Voltage type has 0-10V and -10 to 10V. Current type mainly has 4-20MA,0-20MA. Then the module converts the analog quantity into A number between +32767 and -32768 through A/D conversion, and then implements the control. The function of the signal template is to convert various process i/o signals. The input signals are converted into digital quantities, which are easy for plc to identify, process and analyze. The output is converted into analog to various regulating mechanisms for execution, or the output is converted into a 2-bit do quantity to control some devices such as start, stop, on and off
