Function
The action to be performed.
The type of data transfer required.
Used to stipulate the path to the CPU in certain PLC's.
Paths vary and are dependent on the structure of the
network.
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.
If the parameter is specified, the data will be stored in
the specified format which may be different to the
format of the tag being polled. If the parameter is not
set, the Data Type of the Data Array will be used. This
parameter is only applicable to Data Table Write when
FieldServer is the Client. The Data Type of the Data
Array will be used for Data Table Reads when the
FieldServer is the Client. Refer to Appendix A.4 for more
information.
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 C for further information.
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.
