project description
While a bearing factory in the north continues to expand its business, new plants are needed for larger-scale production. The new plant covers an area of ​​about 2,000 square meters and houses about 60 machine tools, robots and other equipment for daily production. At the beginning of the planning and design of the plant, the manufacturer assesses whether the building is wired or wireless for data communication. After a number of evaluations such as wiring costs, labor costs, maintenance costs, and loss costs, the customer decided to use wireless communication in the factory.
In order to ensure that each machine's data is transmitted to the control room in a timely manner to facilitate centralized management and monitoring of the entire assembly line, customers need to place a wireless client on each machine and use signals to cover the wireless AP of the entire plant. , to ensure that each wireless client's data can be transmitted to the control center through the wireless AP. In addition, because the PLC on the machine tool has a serial port and space is limited, the requirements for wireless clients are very high.
System requirements The wireless client is small and compact, and the serial wireless AP signal needs to cover the whole factory building, and it also needs to be connected to the control room through the wireless way. In order to cooperate with the PLC, it must meet the system's data transmission delay<100ms. The product must have industrial specifications. And adapt to the cold weather in the north, good anti-interference
Moxa solution
In order to effectively transfer the data collected by the machine or robot on the PLC, and the space reserved for the machine is limited, the customer selected the Moxa compact wireless client AWK-1127. The Moxa AWK-1127 series wireless client supports IEEE 802.11 a/b/g and is Moxa's industrial wireless client with the smallest size. Its product design is compact, even lower than the height of a can of soda. Not only that, it also comes with a RS-232/422/485 serial port, you can connect to the PLC's serial port. In this way, it can not only take up space, but also can effectively integrate PLC to realize wireless communication of machine data.
In the selection of wireless APs, customers chose Moxa's industrial-grade dual-radio AP/bridge/client AWK-5222 series. After actual field testing, only two sets of wireless signal coverage can be used to meet the entire plant. Because the two wireless APs are far apart and cannot be wired to each other, an industrial-grade wireless AP/bridge/client AWK-3121 is placed in the main control room to establish communication with the AWK-5222. The AWK-5222 has two RF radios, of which the 2.4G band is mainly used for communication with 60 AWK-1127s, and the two APs use a 5.8G communication band to establish a bridge and is performed with the AWK-3121 in the main control room. Communication, this guarantees both stable communications and channel interference.
Moxa's innovative Turbo Roaming wireless roaming switching technology provides <100ms fast roaming switching, enabling fast switching between different APs in the entire wireless coverage area to ensure seamless data transmission. This allows the data collected by the PLC in the entire plant area to be sent by two different APs. Once the signal becomes weak, it can quickly switch to another AP in a short period of time to ensure the stable transmission of data.
In addition, Moxa AWK-1127, AWK-5222 and AWK-3121 have adopted a wide temperature model to support the harsh climate and environment in the North. They support a working temperature of -40 to 75°C and fully meet the on-site environmental requirements.
Why Moxa
Provide a variety of wireless AP/Bridge/Client options to support -40 ~ 75 °C wide temperature, to meet the needs of the site AWK-1127 compact design, can be installed in any small space AWK-5222 dual radio, support 2.4G and 5.8G One-stop pre-sales and vending services reduce overall customer costs
