FB error: MC_TouchProbe. Touch probe mode changed, before the active request was acknowledged.
Description | A job for measuring the position was already sent to the Motion Controller via the MC_TouchProbe function block. This job is still enabled because the function block has not yet received an acknowledgement for the job. Now, another measurement job is to be sent to the motion controller, but the trigger condition for the measurement process was changed. This information is part of the structure which is assigned at the input "TriggerInput" and is stored in the variable FB error: MC_TouchProbe. Touch probe channel changed, before the active request was acknowledged.. This is not permitted as long as a job is active.
Response | Class | - | The new job is discarded and the error situation is displayed at the "Error" and "ErrorID" outputs of the function block. The function block is still waiting for the acknowledge signal of the measuring job previously sent to the motion controller.
Solution | Class | - | As long as a job is enabled, neither the reference to the probing signal source nor the trigger mode of the measurement may be changed.
Error type | -
