Turbo PMAC On-line Command Specification

277

individually modally address a coordinate system using the ADDRESS statement for subsequent
COMMAND statements, and the hardware control panel on a Turbo PMAC can separately select a
coordinate system for its hardware inputs.

Note:

In firmware versions 1.934 and older, all communications ports addressed the
same coordinate system, so an &{constant} command sent over any port set
the addressed coordinate system for all ports.

Example:

; Ask Turbo PMAC which C.S. is addressed

; Turbo PMAC reports that C.S. 4 is addressed

On-line commands #, #{constant},&{constant};
Program commands ADDRESS, COMMAND;

&{constant}

Function:

Select port’s addressed coordinate system.

Scope:

Port specific

Syntax:

&{constant}

where:



{constant} is an integer from 1 to 16, representing the number of the coordinate system to be
addressed on this port

This command makes the coordinate system specified by {constant} the addressed coordinate system
for the communications port over which this command is sent. This is the coordinate system that will act
on subsequent coordinate-system -specific commands sent over this port until a different coordinate
system is addressed with another &{constant} command.

Other communications ports may be addressing different coordinate systems at the same time, as set by
&{constant} commands sent over those ports. In addition, each background PLC program can
individually modally address a coordinate system using the ADDRESS statement for subsequent
COMMAND statements, and the hardware control panel on a Turbo PMAC can separately select a
coordinate system for its hardware inputs.

Note:

Example:

&1B4R

; C.S.1 point to Beginning of Prog 4 and Run

; C.S.1 Quit running program

&3B6R

; C.S.3 point to Beginning of Prog 5 and Run

; C.S.3 Abort program
