n Phase offset: Enter the delay time in ms for current execution for the watch dog inter-rupt. This should be performed if several watchdog interrupts are enabled. Phaseoffset allows to distribute processing time for watchdog interrupts across the cycle.n Process image partition: This parameter is not supported.n Report cause of STOP: Activate this parameter, if the CPU should report the cause ofSTOP to PG respectively OP on transition to STOP.n Number of messages in the diagnostics buffer: Here the number of diagnostics aredisplayed, which may be stored in the diagnostics buffer (circular buffer).n Synchronization type: Here you specify whether clock should synchronize otherclocks or not.– as slave: The clock is synchronized by another clock.– as master: The clock synchronizes other clocks as master.– none: There is no synchronizationn Time interval: Time intervals within which the synchronization is to be carried out.n Correction factor: Lose or gain in the clock time may be compensated within a 24hour period by means of the correction factor in ms. If the clock is 1s slow after 24hours, you have to specify a correction factor of "+1000" ms.n Level of protection: Here 1 of 3 protection levels may be set to protect the CPU fromunauthorized access.– Protection level 1 (default setting):No password adjustable, no restrictions– Protection level 2 with password:Authorized users: read and write accessUnauthorized user: read access only– Protection level 3:Authorized users: read and write accessUnauthorized user: no read and write access5.9.3 Parameters for DPThe properties dialog of the PROFIBUS part is opened via a double click to the submodule DP.n Short description: Here the short description "DP" for PROFIBUS DP is specified.n Order no.: Nothing is shown here.n Name: Here "DP" is shown. If you change the name, the new name appears in theSiemens SIMATIC Manager.n Interface: The PROFIBUS address is shown here.n Properties: With this button the properties of the PROFIBUS DP interface may bepreset.n Comment: You can enter the purpose of the PROFIBUS interface.n Diagnostics: A diagnostics address for PROFIBUS DP is to be preset here. In thecase of an error the CPU is informed via this address.n Operating mode: Here the operating mode of the PROFIBUS part may be preset.More may be found at chapter "Deployment PROFIBUS Communication".n Configuration: Within the operating mode "DP-Slave" you may configure your slavesystem. More may be found at chapter "Deployment PROFIBUS communication".n Clock: These parameters are not supported.Diagnostics/ClockProtectionGeneralAddressVIPA System 300S+Deployment CPU 317-2AJ23Setting standard CPU parameters > Parameters for DPHB140 | CPU | 317-2AJ23 | en | 17-2550 |
