Turbo PMAC/PMAC2 Software Reference

Turbo PMAC On-line Command Specification 316

DELETE PLCC

Function: Erase specified compiled PLC program

Scope: Global

Syntax: DELETE PLCC {constant}

DEL PLCC {constant}

where:

 {constant} is an integer from 0 to 31, representing the program number

This command causes Turbo PMAC to erase the specified compiled PLC program. Remember that

because all of the compiled PLC programs must be downloaded to Turbo PMAC together, the only way

to restore this PLC is to download the entire set of compiled PLCs.

Only one PLCC program can be deleted in one command. Ranges and lists of PLCC program numbers

are not permitted in this command.

To perform the same function for an uncompiled PLC program, the command sequence would be OPEN

PLC n CLEAR CLOSE.

Example:

DELETE PLCC 5 ; Erase compiled PLC program 5

DEL PLCC 0.... ; Erase compiled PLC program 0

DELETE ROTARY

Function: Delete rotary motion program buffer of addressed coordinate system

Scope: Coordinate-system specific

Syntax: DELETE ROTARY

DEL ROT

This command causes Turbo PMAC to erase the rotary buffer for the currently addressed coordinate

system and frees the memory that had been allocated for it.

Note:

Turbo PMAC will reject this command, reporting an ERR003 if I6=1 or 3, if the

ROTARY buffer for this coordinate system is open or executing, or if any

ROTARY buffer exists for a lower numbered coordinate system, or if a GATHER

buffer exists. Any of these buffers must be deleted first. ROTARY buffers must

be defined from high-numbered coordinate system to low-numbered coordinate

system, and deleted from low-numbered motor to high-numbered motor.

Example:

&2 DELETE ROTARY ; Try to erase C.S. 2’s rotary buffer

ERR003 ............. ; Turbo PMAC rejects this; C.S. 1 still has

............ ; a rotary buffer

&1 DELETE ROTARY ; Erase C.S. 1's rotary buffer

&2 DELETE ROTARY ; Erase C.S. 2's rotary buffer; OK now
