Turbo PMAC On-line Command Specification 381

OPEN PROGRAM

Function: Open a fixed motion program buffer for entry

Scope: Port specific

Syntax: OPEN PROGRAM {constant}

OPEN PROG {constant}

where:

 {constant} is an integer from 1 to 32767 representing the motion program to be opened

This command causes Turbo PMAC to open the specified fixed (non-rotary) motion program buffer for

entry or editing on this port. Subsequent program commands valid for motion programs sent from this

port will be entered into this buffer. When entry of the program is finished, the CLOSE or CLOSE ALL

command should be used to prevent further lines from being put in the buffer.

No other program buffers (PLC, fixed or rotary motion) may be open when this command is sent (Turbo

PMAC will report ERR007 if I6=1 or 3). It is a good idea always to precede an OPEN command with a

CLOSE command to make sure no other buffers have been left open.

No motion programs may be running in any coordinate system when this command is sent (Turbo PMAC

will report ERR001 if I6=1 or 3). As long as a fixed motion program buffer is open, no motion program

may be run in any coordinate system (Turbo PMAC will report ERR015 if I6=1 or 3).

PROGs 1000-32767 can be protected by password. If the PROG is protected by password, and the proper

password has not been given, Turbo PMAC will reject this command (reporting an ERR002 if I6=1 or 3).

After any fixed motion program buffer has been opened, each coordinate system must be commanded to

point to a motion program with the B{constant} command before it can run a motion command

(otherwise Turbo PMAC will report ERR015 if I6=1 or 3)

Example:

CLOSE ; Make sure other buffers are closed

DELETE GATHER ; Make sure memory is free

OPEN PROG 255 ; Open buffer for entry, disabling program

CLEAR ; Erase existing contents

X10 Y20 F5 ; Enter new version of program...

...

CLOSE ; Close buffer at end of program

&1B255R ; Point to this program and run it
