The Diagnostics bundle FB125 comprises a project with function block FB125 and data blockDB125 together with prepared diagnostics displays for SIMATIC HMI units.
The FB and DB are integrated into the PLC program
The diagnostics displays with variables, symbol lists and graphics into the visualization project (ProTool/Pro or WinCC) within STEP 7.
All possible 125 slaves on a PROFIBUS network are represented in 125 squares on the HMI screen. During operation, faulty / failed slaves are identified in color in the overview diagnostics.
It is possible to revert from the overview diagnostics to the detail diagnostics.
The detail view shows type of device, slave address, slot number and type as well as error text and cause of error.
Cable-noise interference, which is recognized by the diagnostic repeater, is also displayed in the diagnostic package.
Using the FB125, you obtain also diagnostic information about your connected AS-Interface!The Siemens DP/AS-I Link 20E (6GK14152AA01) displays all ASI addresses in form of a bit row. The faulty AS-I slave is set to ‘1’.
