CTI 2572-B / 2500C-2572-B Installation and Operation Manual 8
SW5: Configuration Lock. This switch allows you to prevent changes to the module IP parameters via the
Ethernet network. If the PLC Start option is selected, PLC logic will still be able to change the module IP
parameters.
When set to the L
OCKED position, changes to the module IP parameters via the embedded web server Module
Configuration page will be prevented. In the Unl
OCKED position changes will be allowed.
SW6: Firmware Update. This switch allows you to prevent updates to the module firmware. When set to the
CLOSED position, this switch prevents the user from the initiating firmware update using the embedded web
server Update Firmware page.
SW7: Password Bypass. When set to the CLOSED position, this switch bypasses all password checks in the web
server. This is typically used to allow the password to be changed when the current password is unknown or
to eliminate the password check when password protection is not required.
SW8 – SW10: These switches are reserved for future use. They should be set to the open position to prevent
a future use from unintentionally affecting the module operation.
SW11: PLC Interface Mode. This switch allows you to select a PLC interface that is compatible with the CTI
2572 module and other Special Function I/O modules. By default, the 2572-B module uses a high
performance interface mode that increases the amount of data per scan that can be transferred to and from
the PLC and sets the task codes per scan to 8. In most cases, you should use the high performance mode.
However, in instances where minimizing PLC scan time is required, you may wish to use compatibility mode.
This is especially true when the 2572-B module is installed in a remote base where high performance mode
can significantly increase the PLC scan time.
