Modbus

Intro to Modbus

Modbus is a serial communications protocol originally published by Modicon (now Schneider Electric) for use with its programmable logic controllers (PLCs). Modbus has become a de facto standard communication protocol and is now a commonly available means of connecting industrial electronic devices.

Modbus enables communication among many devices connected to the same network and is often used to connect a supervisory computer with a remote terminal unit (RTU) in supervisory control and data acquisition (SCADA) systems.

Modbus Flavours

Various versions of the Modbus protocol exist for serial and Ethernet ports and other protocols that support the Internet protocol suite. Referred to as Modbus flavours, they include Modbus RTU, Modbus TCP, Modbus RTU/IP, Modbus Plus, Modbus ASCII, and Modbus over UDP. There are also a couple of extensions such as Pemex Modbus and Enron Modbus

Of these flavours, Modbus RTU and Modbus TCP are the most popular. The others are relatively rare.

Chipkin provides solutions for most flavours of Modbus including Gateways, Routers, Data Clients, Software, and Stacks.

Below is a list of protocol converter hardware that support the Modbus Protocol:

The Chipkin Modbus Gateway is a protocol converter that converts data from Modbus (RTU/TCP) and makes it available to devices that support a different protocol e.g. Modsbus RTU to BACnet, Veeder Root, HTTP etc.

Chipkin provides both Hardware versions and soft versions of our Gateways. Our software Gateways runs on any compatible version of windows. This means you can select your own computers of any format to run them on or you can run them on a server.

Chipkin provides solutions, not boxes. We work with our clients to ensure the solution to their problems is customized to their needs. Interested? Read More!

QuickServers

QuickServer (FS-QS- 1XXX) is a family of high-performance, fully configurable, and cost-effective building and industrial automation protocol gateways for integrators to easily interface devices to networks in commercial buildings, campuses, and industrial facilities. There are four standard models that come in basic (250 points) or enhanced (500 points) and can connect to serial (RS485 and RS232), Ethernet, and/or LonWorks.

Chipkin has the capabilities to add additional protocols to the QuickServers not supported by the original manufacturer. Interested? Read More!

FS-B3510 Series

The FieldServer Multiport Protocol Gateway (FS-B35XX) is an extremely flexible tool for integrators looking to connect devices to the cloud and on different physical networks, using different links, and speaking different protocols.

With support for 1,000 points (upgradable to 10,000), the Multiport Gateway can easily handle multiple protocol drivers and multiple translations simultaneously with no slowdown in performance. The product includes four serial connections (two RS-232, two RS-485), two 10/100 Ethernet ports, and a LonWorks (Free Topology - FT) port. Interested? Read More!

EZ Gateways

The EZ Gateways is an easy-to- use, high-performance, building and industrial automation protocol gateway for system integrators to be used in commercial buildings, campuses or industrial facilities.

The EZ Gateway provides quick multiprotocol deployment of field protocols to enable integrators to commission the gateway with ease.
