SoftPAC™ is a software-based programmable automation controller (PAC) designed for PC-based control.

Programmed just like an Opto 22 hardware PAC, SoftPAC runs your PAC Control strategy independently on an embedded or standalone PC.

One SoftPAC is included in the PAC Project Professional Software Suite, or you can purchase SoftPAC separately and use the free PAC Project Basic Software Suite to program it. (If you already own PAC Project Pro 9.0 or higher, you can get the upgraded suite including one SoftPAC for free.)

SoftPAC has the following advantages when compared to a hardware PAC:

- You can run your PAC Control control program (strategy) in a Microsoft Windows environment rather than on a standalone or rack-mounted PAC.
- If you are a machine builder or an OEM with a PC already in your product, or if you want to use a PC for a new design, your cost for a controller is reduced.
- SoftPAC takes advantage of a PC’s ability to quickly read and write to files as well as its greater space for data storage. This makes it especially useful for applications requiring extended file storage, frequent access to files, math-intensive processes, or a large number of control flowcharts running at the same time.

For a detailed comparison with hardware PACs, see the SoftPAC Data Sheet (form 2020).


In any version of SoftPAC R9.4c or lower, if you try to use the Update Firmware link in SoftPAC Monitor to upgrade to version R9.5a or higher, you will not find the correct firmware file. To update SoftPAC from version R9.4c or lower to version R9.5a or higher, download and run the software installer on this webpage (click the Download button).
