1. Perform the steps indicated by
*
marks only a t the time of the first start of system.
In principle, turn on the power in order of local channels and remote channels, and then
the master channel. After the program has been completed, the channels may be turned
on a t the same time. When the automatic reconnection function has been
set
a t the time
of hardware setting, the system may be started by first turning on the power of master
channel and then turning on the power of slave channels.
2.
When the system is independently run without Taking data link
a t
the time of program
debugging, the initial program is also required for the master channel. (Refer to
