Up to 128 block programs within the overall user program (all tasks) with the

CS/CJ-series. The execution of each block program is controlled by a single

execution condition. All instructions between BPRG(096) and BEND<801) are

executed unconditionally when the execution condition for BPRG(096) is

turned ON. The execution of all the block programming instructions except for

BPRG(096) is not affected by the execution condition. This allow program-

ming that is to be executed under a single execution condition to be grouped

together in one block program.

Each block is started by one execution condition in the ladder diagram and all

instructions within the block are written in mnemonic form. The block program

is thus a combination of ladder and mnemonic instructions.

Block programs enable programming operations that can be difficult to pro-

gram with ladder diagrams, such as conditional branches and step progres-
