4.6.1.2.1 Time-of-day synchronizationIn the NTP mode (Network Time Protocol) the module sends as client time-of-day queriesat regular intervals to all configured NTP servers within the sub net. You can define up to4 NTP server. Based on the response from the servers, the most reliable and most exacttime-of-day is determined. Here the time with the lowest stratum is used. Stratum 0 is thetime standard (atomic clock). Stratum 1 are directly linked to this NTP server. Using theNTP method, clocks can be synchronized over subnet boundaries. The configuration ofthe NTP servers is carried out in the Siemens SIMATIC Manager via the CP, which isalready configured.1. Open the properties dialog via double-click on the CP 343-1EX30.2. Select the tab ‘Time-of-day synchronization’ .3. Activate the NTP method by enabling ‘Activate NTP time-of-day synchronization’ .4. Click at [Add] and add the corresponding NTP server.5. Select your ‘Time zone’ . In the NTP method, UTC (Universal Time Coordinated) isgenerally transmitted; this corresponds to GMT (Greenwich Mean Time). By config-uring the local time zone, you can set a time offset to UTC.6. Set the ‘Update interval’ you want. Within this interval, the time of the module issynchronized once.7. Close the dialog with [OK].8. Save and transfer your project to the CPU.ð After transmission, the NTP time is requested by each configured time serverand the best response for the time synchronization is used.Please note that although the time zone is evaluated, an automaticchangeover from winter to summer time is not supported. Industrial sys-tems with time-of-day synchronization should always be set in accord-ance to the winter time.With the FC 61 you can determine the local time in the CPU. More infor-mation about the usage of this block may be found in the manual"SPEED7 Operation List" from VIPA.4.7 Setting standard CPU parameters4.7.1 Parameterization via Siemens CPUSince the CPU from VIPA is to be configured as Siemens CPU 314C-2 PN/DP(314-6EH04-0AB0 V3.3) in the Siemens hardware configurator, the standard parametersof the VIPA CPU may be set with "Object properties" of the CPU 314C-2 PN/DP duringhardware configuration. Via a double-click on the CPU 314C-2 PN/DP the parameterwindow of the CPU may be accessed. Using the registers you get access to everystandard parameter of the CPU.NTP methodParametrization via Sie-mens CPU 314-6EH04VIPA System MICRODeployment CPU M13-CCF0000Setting standard CPU parameters > Parameterization via Siemens CPUHB400 | CPU | M13-CCF0000 | en | 18-5076
