10.4 CAREL Master protocol
CAREL Master protocolCAREL Master protocol
CAREL Master protocol
The CAREL Master protocol can be used to read and write variables from/to peripherals that use the CAREL Slave protocol. This protocol is used to talk to I/O
expansions, drivers and fan coil controllers in a simple and economical manner. There are two versions of the CAREL Master protocol: both versions use a list allocated
in the application RAM. The second version also uses atoms to simplify the development of the application and make the commands and the reading of the variables
by the peripherals faster. Both versions allow the supervision of up to 207 devices and 207 variables per device. The limits depend on the availability of user memory.

10.5 CAREL Master 5 expansions protocol
The CAREL Master 5 expansions protocol is a protocol that is optimised for reading and writing variables from/to peripherals that speak the CAREL Slave protocol and
that act as I/O expansions, without intelligence.
