3. Set up the Fisher ROC107 to read from multiple Modbus radars.

!NOTE

The number of requests is based on the Modbus devices in the commloop. In this example, there are three (3) VEGA Modbus radars.

4. In the Modbus Configuration dialog box, click Least Significant Byte First and RTU.

5. In the Starting Request: box, type 1. 6. In the Number of Requests: box type 3.

Configure Modbus RTU Addresses for Multiple Radars 1. Click the Master Table tab.

!NOTE

The RTU address changes for each radar, so each radar must have a unique Modbus RTU address.

2. Change the RTU Address in the first three boxes to the following: Index 1 = 2 (VEGA Modbus RTU Radar address set to 2) Index 2 = 1 (VEGA Modbus RTU Radar address set to 1) Index 3 = 3 (VEGA Modbus RTU Radar address set to 3)

Figure 9: RTU Address


20 48145-US-140707

Set Function Code to Read Data from each Radar 1. Change the Function Code to 4 – Read Input Register to communicate with the

VEGA Modbus Radars. 2. Make certain you change the Function Code to this same code in each of the first

three boxes.

48145-US-140707 21

Set Slave and Master Registers Set the Slave Register and Master Register for the PV, SV, TV, and QV starting at register address 1900 for 10 registers for either Variable (1300):

Index 1 = (Slave Register = 1300, Master Register = 1900) Index 2 = (Slave Register = 1300, Master Register = 1910) Index 3 = (Slave Register = 1300, Master Register = 1920)

Figure 11: Variable Slave and Master Registers

!NOTE

The address range in the master will change for each radar. The slave will always be the VEGA Modbus register storage location.

Configure Modbus Registers Data Storage for Multiple Modbus RTU Radars 1. Click the Registers tab. 2. Change the Start Register and End Register range for each VEGA Modbus radar

to the following: Index 1 = (Start Register = 1900, End Register = 1909) Index 2 = (Start Register = 1910, End Register = 1919) Index 3 = (Start Register = 1920, End Register = 1929)

Figure 14: Start Register and End Register

!NOTE

The Start and End Registers will be unique for each radar. They are assigned by the customer programmers and not VEGA.
