Profisafe modules with iPar functionality support automatic download of parameters to the respective controller via Profisafe-compliant iPar server. Parameters can be set, backed up and documented using Wago-Safety-Editor. The new modules support the tool calling interface (TCI) up to Conformance Class 3, so the Safety-Editor can be integrated into corresponding TCI-compatible engineering systems. The modules can be used with both Profibus and Profinet.
