4. Communication Protocol

KP has the following two protocols and switching can be done by front key settings.

4-1. MODBUS Protocol

MODBUS is a registered trademark of SCHNEIDER company.

MODBUS protocol has two modes namely RTU mode and ASCII mode and switching can be done
using front key settings. It has the transmission function of measurement data and settings, operation
function.

4-2. PRIVATE Protocol

PRIVATE is usual CHINO protocol.

Switching is done by setting the front key. It has the transmission function of measurement data and
settings, operation function.

Old instrument of CHINO products is compatible with new instrument, however the parameter,

which can not be set by PRIVATE, can be set by MODBUS. We recommended using MODBUS
protocol if communication is set newly.
