FGR3 IO Data Sheet

All FGR2-IO models can operate in one of two modes: Modbus and Wire Replacement.

All FGR3-IO models can only operate Modbus mode. Legacy Wire Replacement is not currently supported in FGR3-IO models. New projects should consider using our new ZU1100 Wire Replacement solution.

• In the Modbus mode, all models can be directly connected as an I/O peripheral to a SCADA network.
• For wireless replacement mode, FGR2-IOS and FGR2-IOE can operate as a slave connected to an FGRIO-M master.

The aluminum enclosed FGR2-IOS-CE-U model also includes switchable and protected resistors for convenience when using 4-20 mA sensors.

• All AIs are reported as integers and floating points.
• Pulse counting DIs allow detection and accumulation of pulses up to 1 kHz.
• Data port allows simultaneous operation as a Modbus I/O device and radio slave or repeater.
• Single register access to 16-bit AI value, two-register access for full 20-bit accuracy.
• Protect systems in event of communication loss with programmable failsafe output states.
• DOs control up to 60 W each and have optional pulse-output protection intermittent rated loads.

The FGR3-IO-IOE model is also expandable with the IOE-4422 I/O Series. The FGR2-IOS is UL Class I, Division 2 approved.

Modbus to the FGR IO radios

The following FGR IO radios will allow Modbus communications thru the serial data connection and/or the RF connection:

• FGR3-IOS-CE-U
• FGR3-IO-IOE
• FGR2-IOS-CE-U
• FGR2-IO-IOE

FreeWave Tool Suite Management software for the FGR IO Series of Radios:

FreeWave's complimentary radio network management software

You can download Tool Suite 2.13.2 (which provides support for FGR3-IO product series) and its User Manual from the below link:

• You will be prompted to create a guest account on our sftp.freewave.com website.
• Tool Suite Download - via separate SFTP site in a new tab

Note:  The system this is installed on must have Internet access during the installation, since the installer pulls libraries from the Microsoft site.

Possible Issue: SQL Server Compact 3.5 SP2 stops trying to load (stalls). Then, Tool Suite abandons installation.

Resolution: Manually download Microsoft SQL Server Compact 3.5 Service Pack 2
