4.2 Modbus® security

4.2.1 Control and settings passwords

The CPUs require extra passwords to change settings (i.e., Short Time pickup delay setting) and

4to send commands (i.e., Open Breaker command). These passwords apply to all clients that access the Entellisys system through Modbus communications including the Entellisys HMI, SCADA, or Building Automation, etc.

NOTE: The system ships with default CPU Modbus Settings and Command passwords. The

System Administrator should change these passwords for added security.

The HMI can be configured to transparently send the passwords whenever needed or it can be configured to require all users to re-enter the password when the action is attempted.
