An operation mode change is discarded because in same plc cycle more than one operation mode was commanded.
Description	The MCV_GrpOperationMode function block is used to change the operation mode (Standby, Automatic, MDI, Homing, Manual Mode) of an axis group and then command the required state (Start, Stop, Reset) in this operation mode. The function block is implemented so that there is an input for each operation mode and state. The error message is always output if no job is sent to the motion controller. There are 2 reasons for this: No unique command for the motion controller can be derived from the signals at the inputs for operation mode and state. This is possible if several inputs for switching the operation modes or states receive a rising edge in a PLC cycle. It is not permissible to switch to a different operation mode from every constellation of operation mode and state. The permissible constellations are listed below. The NC program, manual block or homing is finished or interrupted by a stop. The axis group is in manual mode or in standby mode.
Response	Class	-	No job is sent to the motion controller.
Solution	Class	-	Check whether one of the two reasons listed in the description applies to why the operation mode change is not executed. Change the PLC application appropriately to prevent this from reoccurring.
Error type	-
