Appendix A. Useful Features
Appendix A.1. General Notes
The connection type does not need to be specified in the Server side Map Descriptor, but must be
stipulated on the Client side of the driver.
Data_Table_Read as a service can only be used when creating an explicit connection.
Appendix A.2. FieldServer as an Adapter and Scanner.
It is possible for the FieldServer to act as a scanner and an adapter at the same time so long as the scanner and
adapter are configured on different ports. Consequently this functionality is not possible on an FS-X20 platform.
Appendix A.3. Common Paths
Device Typical Path
Direct AB 1 0
AB ENI module 3 1
AB ControlLogix 1756-L55 (With network card 1756-ENBT/A) 1 1 or 1 0
CompactLogix ENI (1769-L31 using the 1761-NET-ENI)
3 1
CompactLogix Direct Connection (P/N 1769-L35E) 1 1 or 1 0
Appendix A.4. Setting the Data Type for stored data.
The default Data Type of stored data is determined by the Data Type of the Data Array. It is possible to configure
the driver to store the data as a different type. This can be achieved by specifying the data type under the
parameter EIP_Data_Type. Note that the EIP_DATA_TYPE parameter has meaning only for DATA_TABLE_WRITE
where the FieldServer is the Client and for DATA_TABLE_READ where the FieldServer is the Server.
Appendix A.4.1. Transfer of Binar y Values using EIP
The standard FieldServer data types do not follow the same naming convention as RSLogix. However, it is possible
to enter the data types in the EIP_Data_Type field in either the FieldServer or the RSLogix format. The following
table provides a cross reference of the FieldServer EIP Data Types and RSLogix Data types:.
EIP_DATA_TYPE should be specified as Bit, BOOL or BOOLEAN.
Set the Map Descriptor length to 1 for the driver to transfer 1 bit. If the Map Descriptor length allows, a chunk of
32 bits will be transferred.
1) A.4.1.-Last Sentence should read: If a length other than 1 is specified then bits will be transferred in 32 bit
words.
2) First Sentence should read: The standard FieldServer data types do not follow the same naming convention as
RSLogix. However, it is possible to enter the data types in the EIP_Data_Type field in either the FieldServer or the
