This window function is a functional instruction by which the data on the
CNC is read or is written.
In the way to process, there are window function high speed and one
processed at low speed.
In case of a low–speed response, The data is read or written by the control
between CNC and PMC
Therefore, it is necessary to ACT=1 of the window instrucion must be
held until the transfer completion information (W1) becomes 1
(interlock).
In a high–speed response, it is not necessity for take the interlock because
the data is directly read.
CAUTION
The window instruction of a low–speed response is
controlled exclusively with the other window instructions of
low–speed response.
Therefore, when the data is read or written continuously, it
is necessary to clear ACT of the functional instruction once
when the completion information (W1) become 1.
It does not work about ACT=1 of the other window
instructions of low–speed response such as W1=1 and
ACT=1 of the window instruction of a low–speed response.
The window instruction of a high–speed response is not
exclusively controlled like a low–speed response.
Therefore, when the data is read or written continuously,
yow need not make ACT=0.
The scan number of times to complete the processing is
summarized on the following table.
TYPE SCAN TIMES UNTIL PROCESSING ENDS
LOW TWO SCAN TIMES OR MORE(This depends on the state of CNC)
HIGH 1SCAN TIME
CAUTION
Enter the desired function code (to which 1000 is added
when data of the second tool post (HEAD2) is read or written
in the TT series, or when data of the second path is read or
written in two–path control of the Power Mate–D.
To perform path 3 read/write operation in 3–path control,
enter a function code + 2000.
