This function block cyclically reads the value of a transmit channel on the PLC. In addition to the axis sending the data (master axis), either the transmit channel or the ParID must be specified.
Requirements for use
This function block can only be used on SG4 target system.
This function block cannot be used with axes on a CAN bus.
This function block should be called in the task class that is defined as the "Task class for NC Manager tasks" in the APC10 configuration. Calling it in a different task class can lead to data inconsistencies on the "CyclicValue" output.
PLCopen axis states in which the function block is permitted to be enabled
All PLCopen axis states, no effect on the PLCopen axis state
