10.8 Modbus Slave protocol
The Modbus Slave protocol is used to make the variables and configuration parameters of the pCO controllers available to a generic Modbus supervisory system.
It is available in two versions: normal (SERIAL*_PROTOCOL=3 or 5), extended (SERIAL*_PROTOCOL=30 or 50)
Note
NoteNote
Note: if used on serial 0-pLAN, set the pLAN address to 0
Note
NoteNote
Note: the ModBus slave protocol cannot be selected at the same time on different serial ports.
Note
NoteNote
Note for pCO1 128KB, pCOXS 128KB, pCOC, pCO2: the protocol is incompatible with CAREL Slave, PSTN, GSM.
Note
NoteNote
Note for pCO1 512KB, pCOXS 512KB, pCO3: the protocol is incompatible with CAREL Slave only if the latter is
activated on the pLAN serial port.

Timeout and polling rate parameters
The timeout and polling rate parameters (WAIT, TREATMENTS, TURNAROUND DELAY, INTERPACKET DELAY) must be set correctly.
Typical values are as follows:
timeout: 1000ms or higher;
turnarounds delay = from 100ms to 200ms.
interpacket delay = turnarounds delay.
