Appendix C. Vendor Information
Appendix C.1. ControlLogix
If EIP Error Code 100 is experienced when using a ControlLogix PLC Message block to read and write data to and
from the FieldServer, it may be possible to resolve this error by choosing to cache the connection in the message
block settings
Appendix C.2. Connection information – Allen Bradley Message Blocks
The Driver is not able to split data between 2 Data Arrays when writing, or to read a Server mapping that is
discontinuous.
For example, on the Server Side:
If:
Server map 1: N21: 0-31
Server map 2: N21: 32-100
This will panic the FieldServer and crash RS view as the DH+ will attempt to map N21: 0-100. If set up as Server
Map 1: N21: 0-100, no problems are experienced.
Similarly on the Client Side, it is not possible to read sections e.g. 32bits to one array and then 16bits from the
same file type to another array etc. Read Blocks must be contiguous.
Appendix C.3. FieldServer not recognised by RSlinx
If RSlinx does not recognise the FieldServer (message “? Unrecognized Device”), load the Ethernet IP EDS file into
RSLinx. This file is available at:

Appendix C.4. Using EIP Data_Types with RSLogix
The EIP_Data_Types defined for the FieldServer are not all supported by the PLC when working with RSLogix. The
following aliases have been created so that data can be transferred in the required format.
EIP Data Types PLC Data Type Data Format
BYTE SINT 8 bit integers
UINT16 INT 16 bit integers
UINT32 DINT 32 bit integers
FLOAT REAL 32bit floats
BIT BOOL Single 1 bit value
BIT_ARRAY, BOOLEAN BOOL_ARRAY Multiple 1 bit values
