data elements exceeds the Map Descriptor length, the list of
data elements will be truncated and an error message will be
printed once per Map Descriptor. Refer to Appendix D for
further information. there can be 200 Floats, 400
Integers or 800 Bytes
Address Instance of the class to be polled.
Depends on the supported
instances for each class.
5.3.3 Driver Related Map Descriptor Parameters – Data Table Read/Write.
Column Title Function Legal Values
EIP_Service The action to be performed.
Data_Table_Read,
Data_Table_Write
EIP_Con_Typ The type of data transfer required. Explicit
EIP_Path
*
Used to stipulate the path to the CPU in certain PLC’s.
Paths vary and are dependent on the structure of the
network.
Any space delimited
numerical value. Refer to
vendor’s
device
documentation. Also see
Appendix A.3, 0 0
EIP_Tag_Name
Tag name expressed in PLC program. The data type of
this parameter is used to set the data format of the
Data Array if the EIP_DATA_TYPE parameter is not
specified.
Maximum length 48
characters.
EIP_Data_Type*
This parameter can be used to specify the data type of
the tag to match the data type used in the remote
device. If this parameter is not specified
the Data Type
of the Data Array will be used. Refer to Appendix A.4
for more information. Alias data types are required
when interacting with PLC’s using RSLogix. Refer to
Appendix C.4 for more information.
Value Alias ( As used in PLC)
Float REAL
Uint32 DINT
Uint16 INT
BYTE SINT
BIT BOOL & BOOLEAN
Length
Number of data elements to be mapped. If the
number of data elements exceeds the Map Descriptor
length, the list of data elements will be truncated and
an error message will be printed once per Map
Descriptor. See Appendix D for further information.
0 to (Data_Array_Length -1)
as specified in Section 4.
EIP_Structure_Handle*
This parameter is required to read/write structures.
The driver supports read/write structures having
members of same type, i.e. all members are of type
Byte, UINT16, UINT32 or Float etc
When this parameter is defined, the number of
structure members must be specified as the length of
the Map Descriptor. Refer to Appendix A.7 for more
information.
