PACData is an application for real time remote monitoring for the Productivity Series Programmable Control product line offered by Automationdirect.com. For this app to function as designed, a Productivity CPU that supports remote connectivity is required. Main Features. - Monitor designated discrete and integer values within the PLC - Access Alarm and Event History - The iOS Zoom feature allows the user to zoom in on specific values on the screen and then save a screen capture if needed - Separate Security Logon requirements offers additional protection for your data. • All current Productivity CPUs support the PACData app. • The Productivity CPU must be using firmware Version 1.1.13.x or later. • Productivity Suite Programming Software Version 1.0.8.x or later is required to program and configure a Productivity CPU to support the PACData App. • The Productivity CPU must have compatible network settings with the device running the PACData App, or the CPU must be accessible from the Internet. • Although the PACData can be configured for password protection, connecting the Productivity Series CPU on an Enterprise network or the Internet exposes security risks. A secure and encrypted VPN connection is highly recommended if the CPU will be accessible from the Internet. A VPN (Virtual Private Network) uses encryption and other security mechanisms to ensure that only authorized users are allowed to connect and that data cannot be intercepted. A VPN greatly reduces the chances of malicious behavior and un-authorized connections.
