Program and configuration memory for storing the application programs and other files in the file system of the PLC. A license key for activating further function block libraries is also included. Individual function blocks from Phoenix Contact, such as those from the SQL and SNMP library or Resy+, are licensed. This means that a fee is charged for each controller on which licensed function blocks are used. The blocks check the license stored on the controller during runtime and enable themselves or run for a limited time in demo mode.
Examples of licensed function blocks:
• Basic control functions for PID controllers with delay time constant in the D component
• Data transfer between the controller and SQL database with event-driven access to tables by means of SQL communication and Data Manipulation Language (DML)
• IT library for sending e-mails with the SMTP function, with DHCP client, DNS, and an FTP client function
• Secure, event-oriented, and inexpensive monitoring of all distributed plants via Ethernet as well as via serial interfaces
Observe the specified performance data of your controller(s) and check that it/they are suitable for your application. For users who do not use the function block libraries, the program and configuration memory is also available without a license as an option.
