Error S120_CU320_2_PN DCC chart 'DCC_1' could not be downloaded to the target device because the required DCB library is not available. Download DCB library TPdcblib_SINAMICS_4_3.2.0 to the drive unit: Right-click drive unit S120_CU320_2_PN -> Select technology packages. The device must then be switched off and on again. Alternatively, select the appropriate library via 'Options -> Block types' in the DCC editor or, if there is no license, via the context menu of the 'DCC chart -> Block types' in SCOUT/STARTER.
