How Immediate Access to an Ethernet Remote I/O Drop can be performed with Quantum Ethernet I/O.
An IU_ERIO function block can be used to updates Ethernet remote I/O drop input and output modules with an optimal response time. The Ethernet remote I/O drop inputs and outputs are updated during the MAST task.
Call this function block in a MAST task. It can be called more than once in a task.
NOTE: To maintain system performance, we recommend that you use no more than 10 executions of the IU_ERIO block during a single MAST task.
Refer the attached file for help on IU_ERIO function block.
