4.1.10 Mode of Operation of PC NC
The operation modes in PC NC can be broadly divided into two: the on-line mode and the off-line
mode. Although the operation mode can be switched using the switch settings, it cannot be
switched in the middle of operation (the PC NC references the system number switches only at
system start-up.)
The contents in each operation mode are as shown in Table 4.1.10.1.
** If the system is started after the system number switches are set into undefined numbers, or the
hardware check program has not been booted and the system number switches are set as B &C,
“Boot Log” Message will come and the system will not start normally.
