Reference data outside the Equipment Sequence

A sequence program can require external equipment data such as the level of a tank or the temperature of an oven. Program parameters are used to make that data available within the sequence program by creating a connection to the appropriate tag. This keeps the data required to run the sequence encapsulated within the program.

A sequence program can also have a dependency on another program. For example, create a connection between a sequencing output parameter from one

Equipment Sequence

program to be used as an input parameter by another

Equipment Sequence

program.
