This page describes three functions of the menus VKRC and VFanuc which change many lines of a program at once:

• Add / remove FB PSPS (VKRC) and Add / remove TC_ONLINE (Fanuc) - the online travel condition of the motion points,
• Comment / uncomment selected text - Ctrl + /,
• Change variable - replace an input, output, merker, flag or timer in the current file, in all opened files or in all programs of the robot.

The online condition is changed with the same expression parser which is used by the syntax check. Operands are never cut into parts (E1 does not match E12), a negated operand is removed together with its !, brackets and OR stay correct.

Undo: the points of Folgen and UPs (Fanuc: Folge, UP, MOTN, Suchlauf) carry data which is not a part of the text (point index, technology parameters). After a change of such a program the undo / redo history is cleared - the status bar shows the message Undo/redo history has been cleared to avoid losing complex block data. Programs without points (Makros) keep one undo step for the whole change.

▲ Add / remove FB PSPS / TC_ONLINE

VKRC » Add / remove FB PSPS and VFanuc » Add / remove TC_ONLINE change the online condition in all points of the current program (or of all opened Folgen and UPs). One of five operations is selected:

Operation	Result
Add FB PSPS as the first sub fold of the point	A new line FB PSPS = ... / TC_ONLINE (...) ; directly after the motion line. Fanuc: a motion written in two lines stays together.
Add to the last FB PSPS of the point	The typed condition is combined with & / AND with the last online condition of the point. Operands which are already there are not added twice; a condition with OR on the top level is put into brackets. A point without online condition gets a new one.
Insert FB PSPS of the previous point if the point has none	The last online condition of the previous point is copied. Operands in Do not inherit (e.g. M146) are left out.
Remove the last FB PSPS of the point	The line is removed without leaving an empty line.
Remove a single variable from the last FB PSPS of the point	The variable is removed from the top level & / AND operands. E41 removes E41 and !E41, !E41 removes only the negated one. If it was the only operand, EIN / ON stays. A variable inside brackets or in an OR condition is not changed and listed at the end.

From point ... to ... limits the change to a range of points (the numbers in the left margin). The range is counted in every file separately, also with For all opened Folgen and UPs. The typed condition is checked before the change (e.g. E1 E2 without an operator is rejected). Example - remove a variable. E75 is removed from the last FB PSPS of the points 21 and 22: Example - add a condition with OR. FB PSPS = E1 + E2 is added to the last FB PSPS of the point. The OR condition is put into brackets, so that it does not change the meaning of the other operands: The same functions in Fanuc work with TC_ONLINE, AND, OR and !. Inner brackets stay, the comment of a signal (DI[5:Part present]) is kept:
▲ Comment / uncomment selected text

Ctrl + / or Comment / uncomment selected text in the context menu of the editor comments or uncomments the current line or all lines of the selection.

• All selected lines get the same state: if at least one line is not commented, all lines are commented; if all lines are commented, they are uncommented. Lines which are already commented are not commented twice. Empty lines are skipped.
• A selection which ends at the beginning of a line does not include this line.
• VKRC: simple lines get -- ... --. A motion point is commented together with all its sub folds, technology and servo gun commands keep their data (both are saved as ;; in the program). A sub fold of a commented point can not be uncommented alone - uncomment the point.
• Fanuc: the comment character from the settings is used (// or !). The motion line and the end of the point (------ ;) can not be commented.
• The selection stays, so the same lines can be uncommented with the next Ctrl + /.
• KRC, ABB and Yaskawa: see KRC comments and folds and Comment / uncomment (ABB and Yaskawa).

▲ Change variable

VKRC » Change variable, VFanuc » Change variable or Change variable ... in the context menu of a variable replaces a variable with another one. The variable under the cursor is taken over; the field can also be filled by hand.

Option	Description
Variable / Change to	VKRC: E, A, M, F, T, S, I, BIN, BININ, ANA, ANAIN with a number (E41, t1, bin12). Fanuc: DI, DO, RI, RO, GI, GO, AI, AO, UI, UO, SI, SO, WI, WO, F, M, R, TIMER (DI[41]). The input is checked; VKRC numbers outside the allowed range are rejected, a change of the type (e.g. input to merker) is shown as a warning.
Also in comments	Changes the variable also in comment lines (-- E63 part present --, ! DI[63] ... ;).
Comment in [ ] (Fanuc)	DI[53:Part present] is found with DI[53]. The comment of the new variable is taken from other lines where it is used; without such a line the old comment is removed. It can also be kept or always removed.
For the current file only	Only the active program.
For all opened files	All opened programs of the same controller type. Programs of other robots are shown with the full path in the list.
For all Folgen, UPs and Makros of the robot of this file (also not opened)	VKRC: Folgen\folge*.src, UPs\up*.src, Makros\makro*.src of the robot of the current file; Fanuc: FOLGE*.LS, UP*.LS, MAKRO*.LS, MOTN*.LS in the folder of the current file. The robot is taken from the current file, not from the active project. Programs which are not opened are checked on the disk; the programs with the variable are opened and changed in the editor, but not saved.

Before the change DReS shows all found lines. Lines of programs which are not opened are marked with [not opened]: If the new variable is already used, its lines are listed too - after the change both signals would be the same. In this case Cancel is the default button: The changed variables are highlighted and marked on the scroll bar: Notes

• Only whole variables are changed: E1 does not change E12, A15 does not change ANA15, M3 does not change SPSMAKRO3.
• VKRC: motion lines, technology and servo gun commands are generated from their parameters - lines of this type are not changed but listed at the end; change them in the command dialog.
• Every program is changed in one step. In Folgen and UPs the undo history is cleared (see above), so check the list before you confirm the change.
• To swap two signals (E41 ↔ E42) use an unused variable as an intermediate step: E41 » free, E42 » E41, free » E42.
• Save the changed programs together; programs opened by the robot scope are not saved automatically.
