Transfer

The User Defined option lets you specify the amount of each reference data type that you want to be transferred on each scan. If the Transfer Additional State RAM check box is activated, it allows you to transfer additional data.

Use the State RAM area to define the size of the data range. All of the reference data that you specify in this area is transferred from the Primary to the Standby controller on every scan (except the defined nontransfer area). All reference data items must be 0 or specified in multiples of 16. A minimum of 16 4x registers is required. The maximum amount of state RAM to be transferred on every scan can be as much as the total amount of available state RAM (10K, 32K, or 64K, depending on the type of Quantum controller).
