Decision Tables - User Guide - PXC4.E16.A - PXC5.E24.A - PXC7.E400.A

Decision tables provide a visual representation of how a specific piece of equipment interacts with other equipment during each mode of operation. Like truth tables, a decision table defines inputs that are logically compared to produce outputs (results).

• Inputs for a decision table are the types of equipment and all possible modes of operation.
• In each row of the table, a piece of equipment is compared to each mode of operation to determine the status of that equipment during the mode.

Table 1-11 provides an example of a decision table that defines six pieces of equipment and four modes of operation.
