Industrial automation software suite

Opto 22 PAC Project 9.2 supports new Snap I/O modules, HTTP messaging, sending email, and legacy G4 digital I/O systems.


Opto 22 PAC ProjectIndustrial automation manufacturer Opto 22 has released its Opto 22 PAC Project 9.2, an upgrade to its PAC Project suite of software applications and utilities that 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. The Snap PAC System and all other Opto 22 products are designed and made in the U.S.A.
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-receives data from generators, motors, and other devices connected on a Controller Area Network (CAN)
  • Snap-IDC-32D module high-density digital input module-senses proximity switches, limit switches, push buttons, and other low-voltage sources
  • Snap-OMR6-A module and SNAP-OMR6-C mechanical relay output modules-switch up to 250 V ac or 30 V dc 6-amp loads per channel and provide a compact, cost-effective way to switch higher voltages and currents without needing breakout boards, header cables, or other interposing hardware.

PAC Control, PAC Project's flowchart-based programming application, adds the customer-requested capability of sending email directly from a PAC controller, with or without attachments, which opens new options for delivering alerts and status information to personnel. 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 useful enhancements for displaying custom dynamic attributes on Microsoft Windows-style buttons and working with grouped graphics when using the AutoCorrect Tags function. Also new in PAC Display is the ability to select one PC to use as a time source, which is useful when several PCs are running the same PAC Display project.

PAC Project 9.2 also supports Opto 22's new 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.

Annual Salary Survey

After almost a decade of uncertainty, the confidence of plant floor managers is soaring. Even with a number of challenges and while implementing new technologies, there is a renewed sense of optimism among plant managers about their business and their future.

The respondents to the 2014 Plant Engineering Salary Survey come from throughout the U.S. and serve a variety of industries, but they are uniform in their optimism about manufacturing. This year’s survey found 79% consider manufacturing a secure career. That’s up from 75% in 2013 and significantly higher than the 63% figure when Plant Engineering first started asking that question a decade ago.
