9.2 SIGNAL STATUS
The PMC signal status can be displayed and changed in real-time.
WARNING
Special care must be taken when the signal status
or PMC parameters are changed. If the change
function is not used appropriately, the machine
operation may be unpredictable.
When there are people near the machine, this
function should not be used.
CAUTION
1 The statuses of some signals cannot be changed.
The status of such a signal is not changed when a
sequence program, the CNC, the MMC, or an
external I/O unit such as the I/O-Link is repeatedly
writing data into the address of the signal. (The
CNC repeatedly writes data to address F, the MMC
repeatedly writes data to address M, and the
external I/O unit repeatedly writes data to address
X.)
2 When a bit signal of the D8192-D9999 addresses
is changed, other bit signals of the same byte
address are overwritten at the same time.
Therefore, it can happen that the signal state might
not change as specified if the signals of the same
D address is changed by the PMC program and the
CNC at the same time.
9.2.1 Procedure
1 Select [Diagnose] - [Signal Status]. The [Signal Status] screen
