Summary:
I have a Hawkeye H-8000 series power transducer, made by Veris Industries, how do I get it working with Citect? 

Solution:
1. This device uses the Modbus (modbus rtu) protocol and has a modbus RS485 port. You can use the Citect communication wizard to set this up, select the Modicon 984 plc for example.

2. The Citect Driver then needs the following parameter in the Citect.ini file;

[modbus]
InitType=3

3. For any device connected to Citect via RS485 it is best to use a RS485 communications board such as the Advantech, PCI 1602B, in this case opto-isolated, it also has drivers for WindowsNT & 98.

4. If you need an external RS232 to RS485 converter, you can also use the Adam 4520 isolated converter for this application.

5. The following framing must be set in the Citect ports: 9600, 8, none, 1.

6. Ensure that each end of the RS485 bus is terminated correctly (into the correct impedance to match the cabling). Shielded twisted pair is the recommended cable.
