Math channel operation; is it possible to hold the value of a totalizer on a process condition?

Yes, SMARTDAC+ and DXAdvanced models with the math option include an operator called HOLD that provides a conditional hold of the computation in the math channel. A practical example is to stop, but not reset, a totalizer computation during a certain process condition. The HOLD math operator uses a 1 or 0 condition to activate or release the hold. This condition can be the status of a DI input channel, remote input, a software switch, or the value of another computation channel. See the instruction manual for more details on this useful math operator.
