Options for Diagnostics and Service

In an automated plant 80 % of faults during operation are process faults. Your diagnostics are plant-specific and cannot therefore be integrated into the controller hardware or firmware. Instead, this must be programmed. To keep related costs low, the use of diagnostics tools is recommended.
Process diagnostics support maintenance personnel with troubleshooting and fault avoidance:


S7-GRAPH the STEP7 Tool for programming sequential controls also offers test and diagnostics functions



S7-PDIAG supports the configuring of process diagnostics for SIMATIC with the LAD, FBD or IL programming languages


SIMATIC TeleService

TeleService allows remote servicing of SIMATIC S7/C7 automation systems or HMI devices using the programming device or PC .
