Opto 22's PAC Project 9.2 supports SNAP I/O modules and HTTP messaging

Opto 22's PAC Project 9.2 is an upgrade to its PAC Project suite of software applications and utilities that is designed to provide control programming, HMI development, OPC connectivity and database integration. PAC Project is part of Opto 22's SNAP PAC System, an integrated system of hardware and software for industrial control, energy management, remote monitoring, and data acquisition applications.

A key addition in this PAC Project upgrade is support for several recently released SNAP I/O modules. These modules include:

  • SNAP-SCM-CAN2B module high-speed serial communications module
  • SNAP-IDC-32D module high-density digital input module
  • SNAP-OMR6-A module and SNAP-OMR6-C mechanical relay output modules

PAC Control, PAC Project's flowchart-based programming application, adds the capability of sending email directly from a PAC controller, with or without attachments. Other additions in PAC Control include new commands for using the HTTP protocol to exchange data with web servers, synchronizing the controller's clock with an external Network Time Protocol (NTP) server, as well as commands to manipulate floating-point values, parse or create binary data when communicating with other devices, and atomically copy a bit from one variable or table element to another.

PAC Display, PAC Project's HMI development and runtime application, adds enhancements for displaying custom dynamic attributes on Windows-style buttons and working with grouped graphics when using the AutoCorrect Tags function. Also new in PAC Display is the ability to select a single PC to use as a time source.

PAC Project 9.2 also supports Opto 22's G4EB2 brain, which allows automation professionals to integrate an existing, legacy G4 digital I/O system with a SNAP PAC System over an Ethernet network without incurring the cost and downtime needed to change existing I/O or field wiring. The Ethernet-based G4EB2 directly replaces a 32-channel brain in a legacy mistic serial or Pamux system.
