New RTC in SNAP-LCM4 and SNAP-LCSX controllers affects firmware compatibility


Applies To:

SNAP-LCM4
SNAP-LCSX-PLUS
SNAP-LCSX

Versions Affected:

See below in RESOLUTION


Symptoms:

The real-time-clock (RTC) chip used in SNAP-LCM4 and SNAP-LCSX controllers is obsolete and has been replaced by an equivalent part. As a result, older firmware versions do not work in controllers with the newer RTC chip.

Resolution:

The following lists the first firmware version that supports the new RTC and its respective controller:

  • SNAP-LCM4 and R4.1e
  • SNAP-LCSX and R4.1d
  • SNAP-LCSX-PLUS and R4.1d

If you are using FactoryFloor 3.1, 4.0, or 4.1, use the most current R4.1 firmware version for your controller.

If you are using FactoryFloor 3.0 or lower: FactoryFloor software versions 3.0 and lower are not compatible with firmware 3.1 or higher. This means your controller can’t use the updated 4.1 firmware versions listed above.

If you’re using FactoryFloor 3.0 or lower, we have a special firmware, version S3.0c, for your controller. This firmware recognizes the newer RTC and works with the older versions of FactoryFloor. You can download the S3.0c firmware file from the Opto 22 FTP site.
