Versions Affected:

Problem was discovered in version: R9.1b
Problem is fixed in version: R9.1d

Resolved In Version:

Problem is fixed in version: R9.1d

Symptoms:

If the PAC Control commands Move I/O Unit to Numeric Table and Move I/O Unit to Numeric Table Ex are used with a disabled I/O unit that was not disabled by a control engine, then the IVAL values are not copied to the destination table. A disconnected communication cable or an I/O unit that is powered off are examples of when a controller does not disable an I/O unit.

This problem also affects I/O units that are enabled at the time the commands are used, but become disabled because the I/O unit experiences a problem and as a result, does not respond to the command.
