Function
• A batch readout (designated number of words) of step operation statuses is executed at the specified block.
• The readout results are stored at the "(d)" device as shown below.
• The bit corresponding to the unassigned step No. (nonexistent step No.) in the read data turns to "0".
• If the read data range exceeds the maximum step No. in the block, the data of the next block No. are read. When there are
no blocks in and after the block to be read, "0" is stored into the remaining bits.
