Chapter8 Communication Function

8.1.7 1:1 Built-in communication between MK80S's
1) Introduction
1:1 built-in communication between MK80S'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 between MK80S's in 8.1.2 "System configuration method
using built-in communication."
