6.5 Point Push Interface Definition

Point Push is an IEC 104 Server feature used to manually enter IEC 104 point data, date and time,
and/or flags information into the internal database of the EIS001 module. This feature is available in
either SOE mode, or NON-SOE Mode. It can be used to interface a Controller to an SOE or record-
based system (local or remote) so that records containing information from the source can be
transferred to the EIS001.
Point Push works by specifying a CPU memory interface region for the EIS001 to monitor. The
memory space specified is formatted with a custom record format that will be used by the EIS001 to
accept point push records.

6.5.2 Record Format

The Point Push Record Format consists first of a 3-word Header Section and a 13-word Record
Section. The Record Section may be repeated up to eight times. Each iteration is concatenated to the
preceding Record Section.

Note: While the Point Push interface is operating, it continues to modify the header section. Note
that it takes multiple scans to accomplish a Point Push.
