ABB GJR2326500R1011 88VU01C-E Module

The control diagnostic system (CDS) builds on two of Procontrol P14's unique features: that each I/O has its own microprocessor and is therefore independent and able to monitor and diagnose itself; and that all process data is available via the bus to all other modules within the system. As a result, CDS is able to recognize all the modules in the system and display them graphically together with their current status information.

Each I/O module communicates its status data, type and location. From this information, CDS generates the control system graphically on the screen and shows all the cabinets. Cabinets can be individually identified and their states are indicated by different colors. Clicking on a cabinet 'opens' its door and shows the modules in their racks graphically. Clicking a second time on a module displays the current contents of the diagnosis register of that module. If a failure occurs CDS guides the user by highlighting the  cabinet, module and register concerned and by displaying a description of the cause.CDS also provides an online recommendation for corrective action. It includes a report function for analyzing control system and process disturbances such as crossing a limit value. Recorded data can be filtered according to period of time, components and type disturbances. CDS's clear graphic displays enable a comprehensive diagnosis down to the transmitter level without having to be specially configured. This makes it a valuable instrument for efficiently diagnosing and correcting disturbances.
