Applies To:

SNAP-PAC-S1
SNAP-PAC-R1
SNAP-PAC-R2
SNAP-UP1-ADS
SNAP-UP1-M64
SNAP-UP1-D64
SNAP-LCE

Versions Affected:

Problem was discovered in version: R8.0a SNAP PAC control engines, R7.2d Ultimate I/O control engines


Problem is fixed in version: R8.0f SNAP PAC control engines, R7.2h Ultimate I/O control engines

Resolved In Version:

Problem is fixed in version: R8.0f SNAP PAC control engines, R7.2h Ultimate I/O control engines


Symptoms:

Some 64-bit integer table element bit values in PAC Display projects or OptoOPCServer clients may have unexpected results. The variables appear not to change, and no error is reported. This behavior is related to controller firmware support.

Control commands affected:
Numeric Table Element Bit Clear
Numeric Table Element Bit Set
Table Element Bit Clear
Table Element Bit Set

For example, if the PAC Display project contains a graphic with an operator driven dynamic attribute to set a bit in a 64-bit table element, the selected bit may not change at Runtime.
