Adding logical nodes for a sequence

At a minimum, each added sequence logical device should have the predefined SEQG-
GIO1 and STEPGGIO1 logical nodes with data objects. The SEQGGIO logical node
has data objects related to the entire sequence functionality, whereas the STEPGGIO
logical node has data objects for a step in the sequence. The predefined logical nodes
and data attributes for a sequence logical device are described in Table 3.4-1.
The description parameter of the data objects in the logical
devices is used in event reporting for sequence execution. To
be able to identify the step number involved, edit the
description parameter of the "St" data object for a STEPGGIO
logical node.
Additional STEPGGIO logical nodes should be added for a sequence with multiple steps.

To add additional logical node objects:
1. Right-click the sequence logical device and select New > Communication >
Sequence Step LN.
