SYSMAC CP1L Getting Started Guide
By using RS-422A/485 option boards, up to 10CH of data per CPU unit can be shared
by as many as 9 CP1L/CP1H/CJ1M units, without the aid of a program.
Current temperature information is exchanged by boilers.
This setup may be used to adjust boiler temperatures according to the other boiler
conditions, or to monitor the boilers from a single location.
