8.1.7 1:1, 1:n Built-in communication between MASTER-K120S's
1) Introduction
1:1 built-in communication between MASTER-K120S's is that which constitutes a built-in communication system with the
method of 1(master) : 1(slave). Setting Base parameter and communication parameter in KGLWIN can easily constitute this
system. Communication protocol currently applied is the same with Cnet I/F used for MASTER-K. Main functions are following.
It can organize device area into 64 data access blocks by WORD unit, and set a communication time-out limit for each
block.
It can reestablish flag in relation with error codes and slave PLC operating mode according to parameter setting.
It can reset flag related with error codes and sending/receiving error frequency of each parameter.
It monitors communication status, using monitoring function of KGLWIN.
This communication cabling map is the same for (3) 1:1 Connecting with other MASTER-K120S in 8.1.2 "System configuration
method using built-in communication."
