High Resolution Modbus RTU Protocol IO Modules
for PLC, HMI, SCADA, etc.

The FDC-IO Modules offer Analog & Digital IO modules (Modbus RTU slave) for data acquisition and other applications offering reliable low-cost solution for distributed IO applications to PLC’s, HMI’s and/or PC based SCADA systems. All modules have LED indicators for visualization of IO status (digital), fault diagnostic analysis and easy DIP Switch configuration for Modbus addressing from 1 to 127.

PC based configuration software, IO Studio, is provided and used for module configuration, viewing real time data and when necessary to check IO status. Module Modbus address is configured by DIP Switch.

The optional IO Studio DAQ ( Data Acquisition) software provides the same features as the IO Studio configuration software but also Real time viewing & data acquisition of RTU/Modbus TCP slave devices like the FDC-IO Modules. The software shows real-time data in the form of digital values, bar graphs, trends, etc. as well as a Historical Data Viewer with a maximum of 1024 tags. The IO Studio DAQ software carries a modest sell price (less then $200) it will run in demo mode for one hour and a demo only version may be downloaded here; IO Studio DEMOA.

Download the IO Studio DAQ software here with a demo mode that is good for one hour of use. Purchase of the software provides a Hardware lock (Key Pro) that plugs into the host PC's USB port. For detailed information download the FDC_IO_Studio_DAQ_Manual_UMDAQC.pdf
