Two and three position slide switches are located on the front of the CPU. left
When in the top position and there is no memory, the switch is used for memory protection
Protection in the middle and bottom positions. Three position sliding switch on
The right side is used to select the communication parameter settings of Modbus (RS-232) port.
The following figure shows the three options available to cpu42402:
unit
Set the slide switch to the top position to assign ASCII functions to ports; this
The following communication parameters have been set and cannot be changed.
Setting the slide switch to the middle position will assign a remote terminal unit (RTU)
Functions of ports; The following communication parameters have been set and cannot
Change.
Note: when the current panel switch is in the following states, the CPU hardware defaults to the bridge mode
Set to RTU or ASCII mode. When connecting the controller, the panel device is connected

switch
Two rotary switches (see figure below) are located on the rear panel
CPU. They are used to set up Modbus Plus nodes and MODBUS ports
Address.
SW1 (top switch) sets the high (ten) bits of the address; SW2 (bottom
Switch) to set the lower digit of the address. The following figure shows:
The correct setting of the example address 11.
The following figure shows SW1 and SW2.
The following table shows the SW1 and SW2 address settings.
Note: the maximum address that these switches can set is 64.
