SoftPAC™ is a software-based programmable automation controller (PAC) designed for PC-based control. It can be used with
groov EPIC,
groov RIO, SNAP PAC R-series, SNAP PAC EB-series, and G4EB2 I/O units.
Programmed just like an Opto 22 hardware PAC, SoftPAC runs your PAC Control strategy independently on an embedded or standalone PC. Also see
PAC Project R10 Release Notes.
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, 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, or math-intensive processes.
For a detailed comparison with hardware PACs, see the
SoftPAC Data Sheet (form 2020).
To find out if you can upgrade to this version for free, see the Opto 22
