Abstract
A method for visually displaying the status of edits utilizes a plurality of visual indicia proximal the portions of edited program segments. Program segments which have not been edited and are currently part of the executable program in the programmable logic controller's processor are represented with solid power rails. Edited rungs which have either been inserted, replaced or deleted are noted as such by I, R and D indicia proximal the power rail of the rung. An asterisk symbol (*) is used to visually identify rungs that have been modified at the workstation but which have not yet been downloaded to the controller. Other visual indicia identify to a workstation operator rungs which have been verified. When the controller is put into test edits mode, the state of the program in the controller prior to downloading the edited program segments is maintained but is not executed and the edits are resolved into the program executing in the processor. Inserted program segments are visually represented as a solid line indicating they are currently part of the program being executed in the controller. Replaced and deleted program segments are visually represented in dotted lines as they are no longer part of the program being executed in the remote processor. In the event the operator deletes a program segment which has been downloaded to the controller, the program segment is visually represented with small d indicia which informs the operator that rung will be deleted at the next download.
