Communication Cartridges
Communication cartridges can add RS-232C communication ports and RS-485 communication ports when connected to the CPU
module's cartridge slots. These cartridges support the maintenance communication function, the user communication function,
and the Modbus communication function. The RS-485 cartridge also supports the data link function.
Note: The communication cartridges can be used by connecting them to the CPU module's cartridge connectors. They cannot be used in the HMI
module's cartridge connector.
