Controllers: PAC system gets microSD memory card slot

All Opto 22 standalone and rack-mounted automation controllers now have a microSD card slot that supports standard microSD memory cards up to 2 GB in capacity.


Temecula, CA – All Opto 22 standalone and rack-mounted programmable automation controllers are now equipped with a microSD card slot in the top of the controller that supports standard microSD memory cards up to 2 GB in capacity. Removable data storage in controllers also enables easy firmware and control strategy updates. The cards can be used to store process and other machine control data, which can be accessed at any time via file transfer protocol (FTP) or through control strategies written in PAC Control, Opto 22's control strategy development software.

When using a microSD card in a SNAP PAC controller, users get an extra 2GB of storage capacity-allowing a greater amount of controller and I/O data to be recorded and stored.

Machine builders, original equipment manufacturers, and others with controllers embedded in their enterprise equipment and systems can use microSD cards to update and test firmware on Opto 22 controllers. They no longer need to physically connect their non-networked controllers to a laptop computer and upload new firmware using PAC Control utilities. Instead, simply inserting a microSD card with new firmware into the controller provides a convenient way to update devices in the field.

Similarly, microSD cards can be used to update and run PAC Control strategies on non-networked controllers. Customers can distribute, test, and swap out new strategies without overwriting existing ones, thereby providing proof of concept for engineers.

All SNAP PAC programmable automation controllers (including the SNAP-PAC-R1, SNAP-PAC-R2, SNAP-PAC-S1, and SNAP-PAC-S2) are equipped with a microSD card slot at no additional charge. By supporting standard microSD cards—widely available in most electronics stores and many other retail outlets— Opto 22 is demonstrating its commitment to using affordable, commercial, off-the-shelf technologies in its product design, the company says.
