Pakscan two-wire digital monitoring and control system for valve actuators and associated plant equipment is designed to provide advanced asset management. It provides Ethernet connectivity; a built-in secure web server; time synchronization; data logging of host messages, field unit commands and status changes; and e-mail notification of alarm conditions. In addition, master station host communication includes two serial ports, two Ethernet ports and an Ethernet configuration port. Via Ethernet, up to 10 concurrent hosts can actively communicate with the master station. Color icons on the master station's HMI screen provide icons that facilitate navigation of the screen menus and the configuration of important settings.
