PLC-502 4G/WIFI Industrial IOT Gateway
| PLC-502 Brief Introduction |
|
PLC-502 is an industrially designed product, and is especially used with PLCs. PLC-502 provides program download and data acquisition functionalities for PLCs that have RJ-45 Ethernet interface, or RS232/RS485 serial interfaces. It supports PLCs from Siemens, Mitsubishi, Omron, Panasonic, Delta, Fatek, etc. PLC-502 connects with 4G network, and with PLC programming tools or SCADA software to implement remote program download and data acquisition.
PLC-502 is an enhanced version of PLC-505. Compared with PLC-505, its panel is more compact, and has stand-up shape in response to customers’ request that can massively save installation space.
PLC-502 not only supports all network modes from China’s three mobile operators, but also has two RJ-45 Ethernet interfaces, one of which (LAN1) can be used as WAN as well, one RS232 and one RS485 serial interfaces. Ethernet interfaces and serial interfaces can be used at the same time. It breaks through network limits, so that it not only supports 4G network, but also 3G: TD-SCDMA/WCDMA/EVDO or 2G: GPRS/EDGE/GSM/CDMA networks, and can automatically switch between different networks. In case there is no 4G network or SIM card does not support 4G, PLC-502 can automatically switch to 3G or 2G networks.
PLC-502 has WIFI functionality as well, and supports 802.11b/g/n protocol. In theory the highest speed can be 150Mbps. Mobile phones, PCs or other devices that have WIFI functionality can bind PLC-502’s WIFI access point and share Internet access via PLC-502. This greatly extends the number of devices that can connect with PLC-502 at the same time.
PLC-502 can use WAN or WIFI network: in case cable network is available, WAN (LAN1) port can be used to access cable network; and in case WIFI is available, PLC-502 can be configured to access internet via WIFI. 4G, WAN and WIFI are all supported by PLC-502, this greatly facilitates customer’s project deployment that customers do not have to choose different devices from different suppliers because of different network access at the spot. This can not only save procurement cost, but also reduce maintenance effort for the projects.
GPS model can be embedded into PLC-502, to implement device location. Set time interval of transmitting GPS location data, then after PLC-502 connects to data center, it will transmit location data to data center with the predefined time interval. Data center can also ask for GPS location data at any time by sending commands. Besides, the device connecting PLC-502 can also send AT command via RS232/RS485 serial port to ask for location information.
PLC-502 is easy to use, and is plug-n-play without any configuration. Together with eTung’s eYun platform and Virhub/Vircom software, it can be easy to integrate with PLC programming software, and there is no extra integration effort. PLC-502 is stable and easy-to-use, thus greatly facilitates project deployment.
