The details of this step vary depending on the features and configuration software provided with the thin server.

With the thin server installed in the equipment enclosure and the proper driver installed or selected, the next step is to configure the thin server to link the equipment communication data and control (inputs and outputs) to the network link. If the I/O device includes an integrated server, then the separate thin server may not be required. Alternatively, an I/O device may be selected that includes an integral thin server function. Modbus or an open ASCII protocol) and can be connected to the thin server. If this is required, the I/O devices should be chosen so that they support a standard communication protocol (e.g. These I/O devices can be installed to monitor strategic data or control points on the equipment. In this situation, it may be necessary to externally instrument the equipment or process using additional sensors and I/O. In the extreme case, the equipment to be monitored may have a controller with no external communication port, or the protocol may be unavailable for some reason. In this situation, either the thin server vendor or a third-party developer will be involved to implement the driver required to connect the thin server to the equipment controller.

If the equipment in question uses a non-standard PLC or a proprietary controller, a connection to the thin server device is still possible as long as the controller supports some kind of serial protocol and the vendor can provide the protocol documentation. If the equipment uses a standard PLC protocol or supports another open standard protocol such as Modbus RTU or TCP, then the job of connecting the thin server is usually greatly simplified. In many cases, the communication driver will be available from the thin server vendor as part of the embedded software application. Most PLCs, including products from AB, Schneider/Modicon, and Siemens, support at least a serial connection using communication protocols available from the PLC vendor or third-party suppliers. In a typical installation, a connection to an existing PLC or proprietary controller will be required to extract data or enable control over the equipment. In this system, the web server/data service device ("thin server") provides the connection between the machine or process and the Internet. In a simplified block diagram form, the parts might look like the figure below.

For applications requiring SPC, optimization, or enterprise level software to exchange real time data with the machine/process, a remote server PC and a compatible data exchange service are required.

a data service or interface to handle exchanging data between the local machine/process (server) and the remote system (client).įor remote viewing of the data and/or web pages, the only requirement is a standard browser interface.

a web server to make the desired display and/or control pages available to the remote browser or client and.

an interface to the machine or process to be monitored or controlled via the web (network) connection.

So, now that we're all convinced of the benefits of web-enabled automation, what pieces and parts are required to put this technology to work? The basic parts required for web-based data acquisition and control are: So, now that we're all convinced of the benefits of web-enabled automation, what pieces and parts are required to put this technology to work?Įnough has been written during the past couple years to convince most plant managers of the benefits of connecting plant floor equipment and processes to the Internet or Intranet.

This project follows the all-contributors specification.Enough has been written during the past couple years to convince most plant managers of the benefits of connecting plant floor equipment and processes to the Internet or Intranet. Thanks goes to these wonderful people ( emoji key): If you can include a Wireshark PCAP captue, that would be very helpful as well. I need help! I've tested this with an Automation Direct Click PLC, but I need people to test with additional types of PLCs and submit issues. To change this, set simpleAddressing to false Modbus Addressing: By default, register and coil addresses will be 0 indexed, not using Modbus addresses.Start a ModbusTCP server, and listen for all implemented Modbus commands.

The error handling is consistent and easy, and it has a full test suite to ensure repeatable behavior.

It's written in Typescript, so you get easy to use strong typings. The aim of this project is to make it extremely easy to work with Modbus with Node.js. Simple-modbus A simple library for working with Modbus
