New PAC Support for 32 GB microSD Cards

SNAP PAC R-series supports microSDHC cards to 32 GB

Firmware R9.4a for SNAP PAC controllers and brains, just released, provides a great new option for your SNAP PAC R-series controller: support for microSDHC cards up to 32 GB.

PAC-R controllers with manufacture dates of November 2008 (11/08) and newer contain a microSD card slot. Originally these PACs supported microSD cards with a maximum capacity of 2 GB.

But sometimes you need a lot more than two gigs of storage space. With the new firmware plus a new loader (version R6.1a), you can update your existing PAC-R to handle larger cards.

Note that all SNAP PAC R-series and SNAP PAC S-series controllers with manufacture dates of 07/14 and newer will support the 32 GB cards out of the box.

Get all the microSD details in this OptoKnowledgeBase article: KB83929.

Firmware R9.4a applies to all SNAP PAC controllers and brains.
For information about other features and fixes included, see the Firmware Readme.

Get the new R9.4a firmware. Make sure to get the right file for your SNAP PAC part number.
Or if you have several SNAP PAC products, get all firmware in one file.

B1 and B2 Migration: New Network Options

E1 and E2 brain boards offer serial and Ethernet networking

B1 and B2 brain boards have reached their end of life due to the unavailability of essential parts, but E1 and E2 brain boards are ready-to-use, drop-in replacements.

And E1s and E2s offer new functionality as well.

The new boards include both an RS-422/485 serial port and a 10/100 Mbps RJ-45 Ethernet network interface. The brain can communicate over both networks at once and use the Ethernet network for multiple protocols simultaneously.

The result? You can now connect not only to Optomux I/O over serial, but also to:

  • Optomux I/O over Ethernet
  • Any system or equipment that talks OPC over Ethernet
  • Modbus hardware and software via Modbus/TCP
  • SNAP PAC controllers and Ethernet-based brains as well as older Opto 22 devices that use the OptoMMP protocol

Because E1s and E2s are drop-in replacements, you keep all your existing I/O racks, modules, and field wiring intact.

  • The digital E1 replaces the B1.
  • The analog E2 replaces the B2.

Update groov View App for iOS, Android

groov View app on iPhone

Got the groov View app for your iOS or Android device? If so, be sure to get the latest update. Here are some new features you might have missed.

When you're looking at your groov interface, swipe right to see a list of your groov connections. The active one is in green. It remains active, so you can just swipe back to view it again.

On the groov list page, you'll see a new Settings button in the upper left. It opens a Settings page with several options:

  • Set the connection timeout
  • Automatically open a default groov connection when the app is launched
  • Lock settings so that groov connections can't be added, changed, or deleted by someone else using your phone
  • Require a passcode to add, change, or delete connections
  • Hide the status bar (iOS only)

If you want to disconnect from the active connection, tap the connection in the list and choose Disconnect.

The groov View apps are optional apps you can download for free and use to see your groov operator interface on iOS or Android mobile devices. Using an app instead of a browser can help reduce distractions and keep focus on the interface.

To get the free updated groov View app, go to your app store. Use the links below or search for "groov View."

Tech Tip: Where's My Flowchart?

Has this ever happened to you? You open a PAC Control flowchart and see... nothing! Where are the blocks?

Is the PAC Control chart empty?


Your flowchart can seem to disappear if it's scrolled out of sight in the window. But don't worry—it hasn't gone anywhere, and getting it back is easy. Here are a few ways to navigate around a flowchart.

Press zero. This is the fastest way to make a disappearing flowchart reappear. Works like magic. Just press zero, either on the regular keyboard or on the numeric keypad. Bam! Your flowchart pops into view, centered on block zero.

Press F. Another speedy way. Pressing the F key centers the chart in the window and zooms it so the whole chart fits.

Center on Block. Here's how to center the chart on exactly the block you want to see. This method is handy if, for example, you've gotten a compilation error in block 91.

    Center on Block dialog box in PAC Control
  1. Right-click in an empty spot in the chart window and choose Center on Block from the popup menu. (Or choose View > Center on Block. Or just press the letter J.)
  2. In the Center On Block dialog box, notice that blocks are listed in alphabetical order by name.
  3. To sort the list by block number instead, click the Block Id column heading.
  4. Click once to show them in numerical order starting with zero; click again to show them in reverse order (highest block number first).
  5. Double-click the block you want to see. It will appear at the center of the flowchart window.

Don't forget that a lot of chart shortcuts are listed right there in PAC Control. Just click the blue Shortcuts link to see them all:
