Yokogawa Standalone MW100 - Manual (Page 47)

Since N7:100 will contain either a ―0‖ or ―1‖, bit ―0‖ status can be examined for a toggling condition. In this example, when
N7:100/0 is true, Timer T4:0 starts timing. When N7:100/0 is false, Timer T4:1 starts timing. Both timers have a preset
value of 2 seconds. If N7:100/0 stays in either a true or false state for more than 2 seconds, B3:0/0 will energize indicating
a loss of communications with the DX Advanced. This bit could be used to disable any modes or processes that could be
adversely affected by the loss of communication with the channels in the DX Advanced.
