With peer-to-peer communication, up to 32 YS1700 can be
connected interchangeably. Four of the connected instruments can
each output 4 points of analog data and 16 points of status data. Inter-lock system
This makes data exchange and I/O sharing possible since all
instruments under peer-to-peer communications can read all data
(16 analog and 64 status data).
This is optimal for multi-loop control as YS1310
