Device Batch Write Status. Puts communication driver in "BATCH MODE" for drivers that support "Batch Writes" (i.e. writing more than one tag at a time). Not all device drivers support this. Most devices allow only one tag to be written at a time. An example of a driver that supports " Batch Writes" include the Fuji PLC.
Will hold output (writes) to a device when enabled (DevBWT = ON = 1). Outputs to the Device will accumulate in a buffer.
Will write output to tags accumulated in the buffer when disabled (DevBWT = OFF 0)
