1 FSa0626 Project Notes How to test the data 1. From the main menu of ruinet select A for Data Arrays Array Name Array Type Set to zero each time any data in the array is updated. Index Number To look at the details for an array type its index number. In this example, there has been no fresh data written to DA_4xxxx_01 for 18 seconds. eg type: 01<Enter> (if greater than 99 then type 01<Enter> and then use the G key to goto the specific array.

2 2. Look at the config file. Observe where the data is served from. Map_Descriptors Map_Descriptor_Name,Data_Array_Name,Data_Array_Offset,Function,Node_Name,Data_Type,Address Voltage Va-n,DA_Float_01,001,Server,VirtualSentron,AI,001 Voltage Vb-n,DA_Float_01,002,Server,VirtualSentron,AI,002 Data Array and offset

3 3. Now find that array in the list. In this example Array index=03. You see this screen Offset 0 Offset 7 The value in offset 1 is 220. The value in offset 2 is 219.

4 Rev Jul07 Please read this document to completion. It has important info. Please read section 8 Possible Issues Modbus Meter The following notes are intended to 1. help you with your startup 2. allow you to make minor changes if required 3. explain the configuration file We will make any changes necessary and you a revised configuration. Simply ask us. You do not need make changes yourself if you do not feel comfortable 1. Prep for Testing Modbus Consider taking the manuals with you to site. If you have a USB 485 converter for your laptop then download and install this software you can use it to test the Modbus data from the meter. modbus scanner 2. FieldServer Tools and Procedures Please read steps 1 and 2 of the attached support procedure document. Install the tools in prep for site work.

5 3. Settings Modbus The FieldServer has been configured to work with these default settings in the Meter. The following notes show you what to change in the configuration file. Connections Port,Baud,Parity,Data_Bits,Stop_Bits,Protocol,Handshaking,Poll_Delay R1,19200,None,8,2,Modbus_RTU,None,0.100s R1=Serial #1 Must correspond to Meter Nodes Node_Name,Node_ID,Protocol,Port, Sentron,126,Modbus_RTU,R1,

13 8. Possible Issues 8.1 Modbus Address Offset May need to be adjusted by 1. The vendor manual does not provided specific enough information. When the FieldServer reads it reads the 2 nd holding register. Most vendors describe that as offset 1 (offset by 1 from the 1 st ). This vendor seems to call that offset 2. If the offset in the configuration is wrong, expect Modbus connection errors. Bad Values We have to convert two Modbus registers to form one floating point. The vendor manual is not precise so we don t know for sure what order to combine the registers. In this section we move 16 bit info using conversion formulae to a new location.
