Chapter 13 Input/Output Control Statements

IOBLOCK ON/OFF (Statement) [Conforms to SLIM]
Function
Concurrently executes a non-motion instruction such as an I/O or calculation
instruction during execution of a motion instruction.
Format
IOBLOCK {ON|OFF}
Explanation
Use IOBLOCK ON and IOBLOCK OFF as a pair. Non-motion instructions such
as plural I/O instructions or calculation instructions that follow a motion
instruction, can be executed concurrently during execution of a robot motion
instruction.
When a robot motion instruction is issued, the controller interrupts the
concurrent execution and waits the currently executed operation (pass start in
the case of pass motion) to be completed. Then, the controller executes the
next motion instruction. If a non-motion instruction follows the next motion
instruction, it is also concurrently executed with the motion instruction. If
IOBLOCK OFF is executed during execution of a motion instruction in
IOBLOCK, the system proceeds to the next step after execution of the motion
instruction.
