2.

Next, write the desired value to the sub element tag in question. The sub element tag will immediately take on the value written to it.

Note: After a sub element is written to at least once in block write mode, the tag's value will not originate from the controller, but instead from the driver's write cache. After the block write is done, all sub element tag values will originate from the controller.

3.

Once the entire desired sub elements are written to, perform the block write that will send these values to the controller. To instantiate a block write, reference tag address RTC:<element>._SET. Setting this tag's value to 'true' will cause a block write to occur based on the current (last read) sub elements and the sub elements affected (written to). Immediately after setting the tag to 'true', it will be automatically reset to "false." This is the default state and performs no action.
