Input data
Input data is variable data given to each process control instruction. The block word (BW) in the block memory in which the
operation result of the previous process control instruction is stored is used as input data.
*1 For the block memory, refer to the following.
The application of input data varies depending on the instruction used. Refer to the descriptions of individual instructions.
Block memory
The block memory is an area in which the output information of each process control instruction is stored.
The block memory consists of a block word (BW) and a block bit (BB).

■
Block word (BW)
The block word (BW) is an area in which the operation result of each process control instruction is stored. The data stored in
the block word (BW) is specified for the input data for the next process control instruction connected by the loop.
■
Block bit (BB)
The block bit (BB) is an area in which alarm data during execution of each process control instruction is stored. Sixteen bits
from b0 to b15 are represented as BB1 to BB16. If an alarm occurs in any of b1 to b15 (BB2 to BB16) used by instructions, 1
is stored in b0 (BB1). The bits that are not used are cleared to zero.
(1) When storing a real number in the block word, use two words.
(2) The block bit is used by setting each bit of one word to on or off.
