Chemical process machine programming system
First Claim
1. In a system comprising a computer for controlling a membrane filtration process, wherein a memory of the computer contains an operation comprising a plurality of executable steps in the process, a method comprising steps of:
- (A) identifying a first subset of the plurality of executable steps as fixed steps;
(B) identifying a second subset of the plurality of executable steps a variable steps; and
(C) providing to a user of the system an interface through which the variable steps, but not the fixed steps, may be modified.

Abstract
The present invention provides an operation editor that includes a user interface for programming operations to be performed by a chemical process machine. Through the user interface the user may specify that one or more of the steps in an operation be variable. Such variable steps may subsequently be edited by the same or another user when the operation is incorporated into a procedure. Steps in the operation that are not variable are fixed and may not be edited when the operation has been incorporated into a procedure. Furthermore, individual fields in a variable step may be either variable or fixed. The present invention also provides a procedure editor that includes a user interface, which allows the user to edit variable steps within the procedure'"'"'s operations. The procedure editor presents to the user for editing only those steps within the procedure that are variable.
