NOTE
1 I/O of channel 2 of the I/O Link can be assigned.
This area is usable when the I/O Link point extension option is selected.
2 This area is reserved for the PMC. I/O cannot be assigned to this area. Do not use this area
for sequence programs.
3 This area includes an area reserved for the PMC. The actually usable address range depends
on the CNC system configuration.
4 Use this area when the CNC is a multipath system. This area includes an area reserved for
the PMC. The actually usable address range depends on the CNC system configuration.
5 This area is reserved for the PMC. Do not use this area for sequence programs.
6 This area is a special relay area managed by the PMC system program. When using this area,
follow the description of each signal.
7 In an ordinary system, this area can be used as with the internal relay (R) area. The extended
relay (E) area is volatile, but a signal is input to or output from a memory card as a PMC
parameter. When a PMC parameter is read, the E area is initialized to the state present at the
time of PMC parameter output.
8 Message display state signals corresponding to message display request signals on a
one–to–one basis. This area cannot be written to.
9 This area is used for the fixed counter instruction (CTRB instruction), which specifies a preset
value as a constant.
10 This area is a special relay area for PMC management software. When using this area, follow
the description of each address.
11 This area is reserved for the PMC. Do not use this area for sequence programs.
