-===== Modbus RTU Slave =====
+Choose the protocol and device role first, then open the corresponding command page. The RS-232, RS-485 and UART terminal roles and ''Serial'' numbers depend on the product model.
-Set the M and D memory sizes with ''ImodbusRTUMem()'' and the start addresses with ''ImodbusRTUAdr()''. After ''ImodbusRTUInit(serial, slaveId, baudrate)'', keep calling ''ImodbusRTU()'' in ''loop()''.

-===== Modbus RTU Master =====
+If communication fails, check the selected protocol, electrical interface, baud rate, station address, parity and wiring in that order. See the [[:en-us_commands:builtin|built-in command manual]] for command usage.
-Initialize the port with ''ImodbusRTUmasterInit()''. Use ''ImodbusRTUmaster()'' for a single request, or ''ImodbusRTUmasterAdd()'' and ''ImodbusRTUmasterRun()'' for registered requests. Check the returned status against constants such as ''IMODBUS_RTU_SUCCESS'', Timeout and CRC error.

-===== LS Industrial Systems Cnet Slave =====
+[[:en-us_commands:builtin|← Built-in command list]]
-Set the M, D and R areas with ''ICnetMem()'' and ''ICnetAdr()'', then call ''ICnetInit(serial, slaveId, baudrate)'' and call ''ICnet()'' in ''loop()''.
-===== Mitsubishi MC Protocol Slave =====
-Set the X, Y, M and D areas with ''IMcMem()'' and ''IMcAdr()'', then call ''IMcInit(serial, stationNo, baudrate)'' and call ''IMcProtocol()'' in ''loop()''.

-Check the product-specific ''Serial'' number, RS-232/RS-485 interface, baud rate, station number, parity, termination resistors and DIP switches. Configure each port so that multiple protocols do not use it simultaneously.
