Modbus TCP is a widely used industrial protocol that is communicable over Ethernet. This works out great for data logging applications in buildings with existing Ethernet networks or remote sites with an internet connection.
There are countless data logging software packages that run on PCs and Ethernet-connectable controllers (PACs and PLCs). These include Indusoft, Wonderware, LabVIEW, and our free EZ Datalogger*.
By adding Modbus TCP Data Acquisition modules like our ET-7000 series or Modbus TCP rack-based I/O to an existing Ethernet network, you can easily communicate and data log to any of these data logging software packages.
We offer many combinations of I/O counts and types. Simply select the module that has the correct number and type of I/O to match your sensors. If your I/O count is larger, you can add as many modules to your network as necessary. This also makes it easy to expand the system to match your needs. They can even be installed at remote sites and pass data through the Internet using Modbus TCP.
The ET-7000 modules are configurable using a web browser and are simple to deploy. Most of the time, setup consists of giving the module an IP address on your network and choosing the I/O type to match your sensor.
We offer free technical support and will be happy to help you choose the appropriate models to suit your application.
Note: The free EZ Datalogger version requires at least one ICP DAS data acquisition module to be connected and is limited to 64 I/O tags.
