Opto22: SoftPAC Controller

With Ethernet fast becoming the de facto network on the plant floor and wireless no longer viewed as an unreliable industrial communications technology, it seems there are fewer and fewer arguments these days over automation technologies. One argument that does persist, however, is over the value of traditional hardware-based control (PLC and DCS) versus PC-based control.

Both sides of this argument have their passionate supporters, so it makes sense for a company producing controllers to offer both options. And that’s what Opto 22 is doing with the release of SoftPAC (scheduled for availability in late October 2012).

With its PC speed, memory and file handling capabilities, SoftPAC is a software-based programmable automation controller that can be used in complex control and data acquisition applications as well as applications that require handling of basic tasks such as logging, manipulating, and exchanging large amounts of data.

An added benefit for OEMs, according to Opto 22, is that the SoftPAC can reduce costs for manufacturers who integrate PCs into their products. By running SoftPAC on the PC built into the machine, manufacturers can avoid the cost of a separate, hardware-based controller. Doing so also saves valuable footprint space inside the machine.

Other SoftPAC features include:
• Memory extension. Hardware-based PACs have a fixed amount of RAM for program memory and logic— usually 16 MB or 32 MB. By using PC RAM, SoftPAC can provide up to 64 MB RAM.
• Multi-Core. Running on Microsoft Windows 7 (32-bit or 64-bit) or Windows XP (32-bit) operating systems, SoftPAC can operate on multiple cores and processors.
• PC or Network Storage. SoftPAC can store gigabytes of data on the PC’s hard drive or anywhere on your network.
