12.1.29 M Code Commands for Displaying Operator Messages
Overview
The comment found in the same block as that containing the M code
command specified as a parameter may be displayed on the operator
message screen. At the same time, MF and the M code are reported to
the PMC. When a sequence notifies ,the OPEN CNC, therefore, it can
read the operator message using the appropriate window function.
Explanation
During the execution of a part program, any character string may be
reported to the OPEN CNC so that the application on the personal
computer can issue setup and other instructions to the operator.
The FS16/18/21 allow the comment in the currently executed block to
be read with the appropriate window function. Thus, if a comment is
specified in the same block as that containing an M code and a read
request is issued from a PMC sequence to the OPEN CNC, the
comment can be acquired on the personal computer.
On the FS15, no comment remains in the executed program display.
With this function, when the M code specified as a parameter is
executed, the comment specified in the same block is displayed on the
operator message screen (type: operator message by a custom macro
command). When a read request is issued from a PMC sequence to the
OPEN CNC, the comment can be read by using the operator message
read function "cnc_rdopmsg()" on the personal computer.
When this function is executed, the system does not automatically
switch to the operator screen. Nor does operation stop. When the PMC
returns a completion signal for the auxiliary function, the system starts
the execution of the next block.
The operator message is cleared at the next cycle start.
If operator message display with a custom macro is specified, the
system switches to this message.
