Cautions for master and slave tests
1) Before making the tests, move the RUN switch of programmable controller to the STOP po-
si tion.
2) When the KJ71P3 is used, perform reset operation by use of the RESET switch of CPU in i t s
own channel.
3) When the system to be tested consists of 3 or more channels, be sure to set the channels, which
are not put to the master and slave tests, to the offline mode.
