Ex.
When "BMOV BL1\S2 D0 K2" is executed in the following case,
• Block 1: The maximum step No. is 10 (S10) and step 5 (S5) and step 8 (S8) do not exist
• Block 2: The maximum step No. is 12 (S12) and step 3 (S3) does not exist
• Block 3 and later: Do not exist
data are stored as shown below.
0
• If there is a nonexistent block in the data to be read, the nonexistent block is omitted and the data of the next existing block
are read.
Ex.
When "BMOV BL1\S2 D0 K2" is executed in the following case,
• Block 1: The maximum step No. is 10 (S10)
• Block 2: Nonexistent
• Block 3: The maximum step No. is 12 (S12)
• Block 4: The maximum step No. is 15 (S15)
data are stored as shown below.
• In the activation step batch read instruction, do not specify a nonexistent block/step. An error will not occur if a nonexistent
block/step is specified. However, the read data are undefined.
• Specify the step as described below.

Description
Use "K4Sn" when specifying the step in the current block.
Use "BLm\K4Sn" when specifying the step in the SFC program.
Use "BLm\K4Sn" when executing the step activation check instruction.
When the block number is not specified, specify the block number with the BRSET instruction. Note, however, that the
following CPU modules cannot use the BRSET instruction. When no block number is specified, the block 0 is set.
• Basic model QCPU
• Universal model QCPU whose serial number (first five digits) is "13101" or earlier
• LCPU
