Modbus RTU and MQTT Soft Gateway

The Modbus RTU and MQTT Windows Gateway acts as a software-based protocol converter. It converts Modbus RTU data and allows it to work on a MQTT Network.
The Web (HTTP, XML, REST, Json, MQTT) driver allows the Gateway to push data to the Web via a variety of Protocols.
The Modbus RTU driver allows the Gateway to transfer data to and from devices via a serial RS485 connection using the Modbus protocol.

Chipkin's Modbus RTU and MQTT Software Gateway is a Windows-based protocol converter. The gateway operates by reading the data from devices that use Modbus RTU The values read from these devices then can be read from a network that uses MQTT. Also, works vice-versa.

The gateway requires minimal configuration and can be considered a "plug and play" component of any network system. It's ready to operate out of the box and can be installed without an engineer's approval.

CAS2500 - Windows

This device is a Software version of our Data Client/Logger and Gateway. It is compatible with an hardware that can load Windows 7 or 10. It allows you to turn any PC that meets the minimum requirements into a Data Client/Logger and Gateway.

Web (HTTP, XML, REST, Json, MQTT) Driver

The Web Diver allows for data to be monitored by remote systems running applications that can issue HTTP or SOAP/XML GET requests – such applications can be easily developed by end users. Of course, this data is available using an Internet Browser such as Internet Explorer or Google Chrome

Modbus RTU Driver

The CAS Modbus RTU driver allows the CAS Gateway to transfer data to and from devices via a serial RS485 connection using the Modbus protocol.  The CAS Gateway can either be a Client, reading and controlling values from a slave, or a Server, serving data to a Modbus Master.

The CAS Modbus RTU Driver supports the following Modbus Functions:

- 01 (0x01) Read Coils- 05 (0x05) Write Single Coil
- 02 (0x02) Read Discrete Inputs- 06 (0x06) Write Single Register
- 03 (0x03) Read Holding Registers- 15 (0x0F) Write Multiple Coils
- 04 (0x04) Read Input Registers- 16 (0x10) Write Multiple Registers
I'd like to inquire about the Modbus RTU and MQTT Soft Gateway CAS-3000-69. Please provide me with a quote for this product.
