PURPOSE:To discriminate success/ failure of latch control by returning an answer back signal inverted at each polling. CONSTITUTION:When a control signal is transmitted from a telemeter master station MS to a telemeter slave station SV at a time A, the slave station SV holds an output from a flip-flop FF as an answer back, When the master satation MS performs polling at the next time B, the answer back signal is returned to the master station MS together with counter data from the slave station SV in response the polling. When the answer-back signal is inverted in this case, it represents the successs of latch control. |
