7bit Mediator is an Ethernet-to-serial gateway for an arbitrary user device protocol. Its main purpose is to speed up communication and facilitate access to controllers that use the non-standard and slow RS-485 fieldbus interface and connect them using the standard Modbus TCP protocol. Exchange via RS-485 is implemented using the popular Lua scripting language. It has one PoE port (power supply from 9 – 48Vdc) for connecting to the network, WiFi – client mode, one isolated RS-485 port.
Connection to the monitoring or automation system of non-standard slow devices for which adding or developing an end device driver is impractical or impossible. Thus, such a device can be simply connected to the system using flexible communication cables Ethernet and Wi-Fi capabilities. Examples of such end devices can be:
With the help of Mediator, you can connect a remote serial device with a COM port (electrical, heat meters, scales, etc.) to the monitoring or automation system via Ethernet and implement communication with it according to a non-standard protocol, using a processor written in the language Lua. A web browser is sufficient to configure the gateway. Mediator works asynchronously, reading the necessary data into the internal memory accessible to clients via Modbus TCP.
