Advanced PACs with PID auto-tune functions

SigmaPAC and Sigma microPAC include advanced PID with auto-tune functions and can handle virtually any number of logic and sequence routines. In addition, both come with Modbus TCP/IP ports and multiple Modbus serial ports.


Ascon has introduced two new programmable automation controllers that provide precision control and analog and digital control in a fully distributable hardware platform. SigmaPAC and Sigma microPAC include advanced PID with auto-tune functions and can handle virtually any number of logic and sequence routines. In addition, both come with Modbus TCP/IP ports and multiple Modbus serial ports.

The units have been used to control high temperature aerospace/military applications, as well as for boiler and steam distribution, plastics processing, and food processing.

SigmaPAC and Sigma microPAC are configured with easy to use graphical IEC61131 programming software called OpenPCS.

Sigma microPAC is ideal for small to medium sized processes and includes onboard analog and digital I/O with some remote and expansion IO capabilities. SigmaPAC I/O modules are connected using standard off the shelf RJ45 connection and support CANopen high speed communications. All I/O modules are high accuracy, fully isolated, and hot swappable, according to the company.

Ascon is a multi-national industrial controls and automation engineering and manufacturing company with U.S. headquarters in Batavia, IL. Established in 1969 in Europe and 2004 in the USA, Ascon designs and manufactures control, instrumentation and automation components for the process and discrete manufacturing industries.

Annual Salary Survey

Before the calendar turned, 2016 already had the makings of a pivotal year for manufacturing, and for the world.

There were the big events for the year, including the United States as Partner Country at Hannover Messe in April and the 2016 International Manufacturing Technology Show in Chicago in September. There's also the matter of the U.S. presidential elections in November, which promise to shape policy in manufacturing for years to come.

But the year started with global economic turmoil, as a slowdown in Chinese manufacturing triggered a worldwide stock hiccup that sent values plummeting. The continued plunge in world oil prices has resulted in a slowdown in exploration and, by extension, the manufacture of exploration equipment.
