Rotary Switch; Baud Rate Switches - Omron C200HW-CORT21-V1 Operation Manual

Physical layout of the Unit

3-1-3 Rotary Switch

Memory allocation

3-1-4 Baud rate switches

The rotary switch is used to set the Special I/O Unit number (or so called
"Machine No.").
The Machine number setting determines which words in the Internal Relay
and Data Memory Areas are allocated to C200HW-CORT21-V1.
The valid Unit number setting range depends on the host PLC's CPU Unit, as
shown in the following table.
CPU Unit models
C200HE,
C200HG-CPU3 -E/CPU4 -E,
C200HX-CPU3 -E/CPU4 -E
C200HG-CPU5 -E/CPU6 -E,
C200HX-CPU5 -E/CPU6 -E,
CS1-series
Any Machine No. in the setting range is allowed as long as it has not been
set on another Special I/O Unit connected to the host PLC. If the same
Machine number is used for the C200HW-CORT21-V1 and another Special
I/O Unit, an "I/O Unit Over" error will occur in the PLC and it will not be
possible to start up the network communication.
Note Always turn OFF the power to the PLC before changing the Machine number
setting. The Unit only reads the Machine number setting during the
initialisation after power-up, i.e. it is not processed at a software reset.
Use a small flat-blade screwdriver to turn the rotary switch; be careful not to
damage the switch.
The DIP switches on the front of the Unit set the CAN communication baud
rate.
Only the first 3 switches are used (BR0, BR1, BR2); the fourth switch (RSV)
is reserved for future use and should remain in the OFF position. The
following table lists all possible DIP switch settings and their corresponding
baud rate.
