2.4 Sequences
A sequence is a macro program, i.e. a set of written steps (instructions) entered
with a guided editor. Once programmed, sequences can be executed by MM8000
and perform a particular set of functions, started by a manual command, a time-
driven program, or an automatic reaction.
The instruction set includes action and control statements as well as declarations
of local variables for storing intermediate results (Fig. 19). Also, VB scripts can be
laun
ched in order to execute external tasks for addressing very specific needs.
Therefore, MM8000 sequences can perform quite complex tasks, thus simplifying
the safety and security operations.
In spite of their powerfulness, sequences are simple to define, thanks to the guided
editor and to coloured text presentation.

The MM8000 can support different ways to execute a sequence:
• Manually, from the Plant Browser: the sequence can be started from a target
symbol, presented as a point in the Plant Browser. A sequence point can as-
