DO signal reaction to a system alarm
If a system alarm occurs in a CNC using this operators panel I/O module,
or if I/O Link communication between the Power Mate and operators
panel I/O module fails, all the DO signals of the I/O module are turned
off. Therefore, due care must be taken when setting up the machine
sequence. Also, the same phenomenon occurs if the power of the Power
Mate or the I/O module is turned off.
Address allocation
For the operators panel I/O module, I/O addresses are mapped as follows.

Output signal
Basically, this operators panel I/O module is allocated a group of DI
addresses (16 bytes) and a group of DO addresses (4 bytes). This address
allocation is explained below.
The MPG interface (MPG counter) occupies DI space from Xm+12
through Xm+14. These addresses are fixed, and Xm+12 through Xm+14
must be allocated as a DI work area to enable the use of the MPG.
Therefore, when using an MPG, allocate DI addresses in units of 16 bytes.
Do not use the DI space from Xm+12 through Xm+14 for Ladder; the
Power Mate processes the MPG counter value directly.
DI address Xm+15 is used for detecting overcurrent and overheating
alarms that occur in the IC used in the DO driver. [For details, see the
section describing the detection of DO (output signal) alarms.] This
address is fixed, and must be allocated as a work area before it can be used.
When using this area, therefore, allocate DI addresses in units of 16 bytes.
