Spectronics Description  
The Spectronics driver allows the FieldServer to transfer data to and from devices over either  
RS-232 or RS-485 using Spectronics protocol. The FieldServer can emulate either a Server or  
Client.  
The information that follows describes how to expand upon the factory defaults provided in the  
configuration files included with the FieldServer.

Hardware Connections  
It is possible to connect a Spectronics device to any of the existing serial ports on the  
FieldServer1. These ports simply need to be configured for Spectronics in the configuration file.  
Configure the Spectronics device according to manufacturer’s instructions.

Configuring the FieldServer as a Spectronics Client  
For a detailed discussion on FieldServer configuration, please refer to the FieldServer  
Configuration Manual. The information that follows describes how to expand upon the factory  
defaults provided in the configuration files included with the FieldServer (See “.csv” sample files  
provided with the FS).  
This section documents and describes the parameters necessary for configuring the FieldServer  
to communicate with a Spectronics Server.  
4.1.  
Data Arrays/Descriptors  
The configuration file tells the FieldServer about its interfaces, and the routing of data  
required. In order to enable the FieldServer for Spectronics communications, the driver  
independent FieldServer buffers need to be declared in the “Data Arrays” section, the  
destination device addresses need to be declared in the “Client Side Nodes” section, and  
the data required from the servers needs to be mapped in the “Client Side Map Descriptors”  
section. Details on how to do this can be found below.  
Note that in the tables, * indicates an optional parameter, with the bold legal value being the  
default.  
Section Title  
Data_Arrays  
Column Title

Legal Values  
Up to 15 alphanumeric

Provide data format. Each FLOAT, BIT, UInt16, SInt16,  
Data Array can only take on Packed_Bit, Byte,  
Data_Array_Format  
Data_Array_Length  
one format.  
Packed_Byte, Swapped_Byte  
Number of Data Objects. Must  
be larger than the data  
storage area required by the 1-10,000  
map descriptors for the data  
being placed in this array.

Appendix A. Advanced Topics – Spectronics  
Appendix A.1. Default Data Types  
When a Spectronics address range is specified, a particular Data Type is implied. The  
defaults are as follows:  
Address range  
40001 - 49999  
30001 - 39999  
10001 - 19999  
00001 - 09999

Appendix A.2. Single Writes  
When writing the default data types can be overwritten using the “Single_Coil” and  
“Single_Register” settings as part of the Map Descriptor configuration. In that case the  
Function codes for writes will be as follows:  
Address range Data_Type  
Function Code (Write)  
40001 - 49999  
30001 - 39999  
Single_Register 6  
Coil  
5.  
Example: FC 6 = Write Single Register  
Add a parameter to the Spectronics client side Map Descriptor called Data_Type.  
If you specify the Data_Type as Single_Register and the Function as WRBC or WRBX,  
then a Spectronics poll with FC 6 will be generated.  
Of course Single_Register implies a length of one, and even if you try to set the length  
longer in the csv file, the length is limited to 1 in the driver.  
Appendix A.3. Write-Thru Operation  
Consider a client Map Descriptor that is configured to read data using a FC 3 (Read Multiple  
Register) operation. It is now possible do a write thru operation on the existing Client Map  
Descriptor by storing data to the Client Map Descriptors Data Array.  
The Write Cache Map Descriptor that is created will use the following function codes  
depending on the Cache Map Descriptor Length and the Clients Node Type.  
Single Register Write - FC 6 - When the length of the Cache Map Descriptor is one. This will  
normally be the case.  
Multiple Register Write – FC 16 - When the length of the Cache Map Descriptor is larger  
than one or the Node_Type has been set to “Block_Mode”.

Appendix A.4. Connection to York Modbus Microgateway  
If connecting the FieldServer to a York Modbus Microgateway, the Node_ID of the  
Microgateway is defined by the address DIP switches. If switch 4 is set to ‘On’ and the other  
switches are set to ‘off’ then Node_ID of the Microgateway is ‘247’, the parity is ‘Even’, and  
the stop bits are 1. Other Node_ID combinations can be found in the York Modbus  
Microgateway Installation Manual.
