5.4 BT, Data block Transformer
This function block is available for easy800-SWD from device version 01 and
for easy800 standard devices from device version 04.
The block transfer function block (BT) is used for transferring values from one
marker range to another (copy data). The marker ranges can be overwritten
with a particular value (data initialization). The following marker ranges can be
transferred and written:
• MB.
• MW.
• MD.
easy800 device allows the use of up to 32 data block transfer function
blocks.
