SIEMENS Simatic S7-1200 SM1223 DC/RLY - 6ES7223-1PL32-0XB0 digital input/output module
Network node could be any device that simultaneously receives and then communicates something over a network. On the other hand, it has limited functions as it can only receive and store this data, as well as create and send new data. A computer is the most widespread and well-known network node, and you will often find it referred to as a computer node or internet node.
Network moduleyou and computer nodes - other types and kinds
Nodes in the Internet and cable networks have gained a lot of popularity. Both at home and in companies, they were connected to the same fiber optic receiver. Another example of a node could be a device that is used to provide an intelligent cellular network service, such as e.g..eu / en / 99-controllers ">controllergas station (BSC) or GPRS Gateway support node. Another network node is the cell node whose job is to provide software with cellular hardware. It does so through the use of antennas that are used to transmit signals to all devices on the cellular network.
P.We also present Supernode, which is a peer to peer node. It works not only as a regular node, but also as a proxy server and device that passes information to other P2P users. These devices therefore require more CPU and bandwidth than other nodes.
Digital input module - the most important information
Network modules b>enable the connection of up to 32 input and output modules. They allow communication via Ethernet with the use of interface modules. They have 8 digital VDC inputs (M - 1800/1), 16 digital VDC inputs (M - 1600/1) and 4 digital VAC inputs (M - 1450/1) in their construction. They have remote communication and comprehensive asymistic support that allows them to create their own software. The modules presented above do not have a connection strip and a screw terminal used to connect the signals in the set. Digital input module
