Applies To:

Firmware and loader for the following SNAP analog input modules when used with B3000, B3000-HA, or SNAP-B3000-MODBUS brains:

SNAP-AIV
SNAP-AIV-i
SNAP-AIV2-i
SNAP-AIV-4
SNAP-AITM2-i
SNAP-AITM-i-C
SNAP-AITM-i
SNAP-AIRTD-1K

SNAP-AIMA-i
SNAP-AIMA-4
SNAP-AIMA
SNAP-AICTD-4
SNAP-AICTD

Versions Affected:

Loader: All versions lower than R1.0b
Firmware: R2.0a to R2.1b

Resolved In Version:

Loader: R1.1a
Firmware: R2.2b

Symptoms:

When any of the affected SNAP analog input modules are used with B3000, B3000-HA, or SNAP-B3000-MODBUS brains, the modules report only -32768 or NaN.

For information about a similar issue affecting some of the same modules but with a different set of brains, review KB91204.

Resolution:

You may be able to update module firmware in the field, but the loader must be updated at the factory. Contact the Opto 22 Product Support Group at support@opto22.com or 1-951-695-3080 for module repair.
