Configure the poke mode

You can use the poke mode to control how the Communication Driver optimizes and folds pokes within a transaction. Select from the following three modes:

Control Mode

Preserves the poke order without folding. This mode is typically used by batch and control applications that depend on the order of the pokes, and on the processing of every item poked.

Transition Mode

Preserves the poke order with minimum folding by keeping the first, second, and last poke values of an item. This mode is used by batch and control applications that depend on the order of pokes but do not process every item poked.

Optimization Mode

Does not preserve the poke order and has maximum folding by only poking the last value of an item. This mode is typically used by HMI applications.
