An intelligent pressure regulator in a process control system is controlled according to a profile constructed by a user on a computer connected to the device. The profile is a multi- step command sequence. The profile includes at least one conditional statement and, optionally, at least one branching statement. That is, the profile includes at least one statement that, depending on whether the statement is true or false, causes the device to execute a first command or a second command, respectively. The profile may also include a statement (e.g., a "goto" statement) that causes the device to skip one or more commands in the profile. |
