ADDRESS
An address shows a signal location. Addresses include input/output
signals with respect to the machine, the input/output signals with respect
to the CNC, the internal relays, the counters, the keep relays (PMC
parameters), and data table. Each address consists of an address number
(for every 8 signals) and a bit number (0 to 7). Enter the symbol table
showing the relationship between the signal names and the addresses into
the programmer by using the keys of the CRT/MDI or the keys of the
keyboard of the offline programmer as in the case of the sequence
program.
For programming, see Chapter III, IV and V.

Fig. 3 Addresses related to PMC
(a) The input/output signals with respect to the PMC, which are
indicated by the solid lines, are transferred via the receiver and the
driver of the I/O board.
(b) The input/output signals with respect to the PMC, which are
indicated by the broken lines, are transferred only in the memory
such as the RAM.
All of these signals can be displayed on the CRT/MDI panel.
(2) Address regulations
The address comprises the address number and the bit number in the
format as shown below.
