Ways of Evaluating the Error DBs

There are four ways of evaluating error DBs:
• Direct readout of the error DB as a record with the programmer or the operator panel
• Interpretation and plaintext message of Blocks 2 to 22 with COM 115F
• SINEC L1 LAN
• The error DB centre is sent to the higher-level operator PLC containing the SINEC L1 LAN
master: evaluation of the DBs at the user level.
• Via programmer bus

Error Messages in Plaintext with COM 115F

With the S5-115F it is possible to display error messages in plaintext on the monitor of your pro-
grammer using the COM 115F programming package.
