PMAC 2 Software Reference

PMAC On-Line Command Specification 253

Remarks

This command assigns the value on the right side of the equals sign to the specified M-

variable(s). It does not assign a definition (address) to the M-variable(s); that is done with

the M{constant}->{definition command.

If a motion or PLC program buffer is open when this command is sent to PMAC, it will be

entered into the buffer for later execution.

Example

M1=1

M9=M9 & $20

M102=-16384

M1..8=0

Function

Report current M-variable definition(s)

Scope

Global

Syntax

M{constant}[..{constant}]->

where:

• {constant} is an integer from 0 to 1023 representing the number of the M-variable;

• the optional second {constant} must be at least as great as the first {constant} – it

represents the number of the end of the range;

Note:

No spaces are permitted between the M-variable name and the

“arrow” double character in this command.

Remarks

This command causes PMAC to report the definition (address) of the specified M-variable or

range of M-variables. It does not cause PMAC to report the value of the M-variable{s); that

is done with the M{constant} command.

When I9 is 0 or 2, only the definition itself (e.g. Y:$FFC2,0) is returned. When I9 is 1or 3,

the entire definition statement (e.g. M11->Y:$FFC2,0) is returned.

Example

M1->.................. ; Host requests definition

Y:$FFC2,8...... ; PMAC’s response

M101..103->

X:$C001,24,S

Y:$C003,8,16,S

X:$C003,24,S
