The RIUP feature enables easy maintenance and it is one of the important features included in the 1756-A4. The 1756-A4 has electronic keying feature like the other ControlLogix chassis. The electronic keying feature helps in preventing the replacement errors and therefore it is included as a preventive maintenance feature.
