Goals and Symptoms
This resolution serves to explain the possible cause of an Error 27 reported on Single axis, 984 series (B-885), Compact or Quantum Motion modules
Causes and Fixes
Response bits allow the 984/PLC controller to receive a pre-defined reply block instead of an echo of the data register. This is optionally used by users to automatically get updated responses every 50 ms. Error 27 may mean that the system is not configured via the Set response bit command to allow access and receive data. This is not a Fatal fault.
