1. both routing and peer to peer Review the User Manual Communication chapter 25 Network for the corresponding configuring details The loading times are increased according to the number of network nodes utilized since the telegram run times for loading and reply telegrams will be correspondingly raised An optimization has been implemented several telegrams running on the path simultaneously in order to keep these dead times as small as possible Siemens AG 465 980 7107 22 Release 04 96 23 3 SIMADYN D Configuring Manual Communication 23 Download 23 4 Release 04 96 Siemens AG 465 980 7107 22 SIMADYN D Configuring Manual Communication
2. 23 Download 23 Download The utility download is designed to load on line configured data or complete programs directly into the memory board of a P32 processor notinto DRAM The transmission procedure can only be started with STRUC G in the basic dialog shell menu item PROG Download A rack reset can also be activated for a rack The loading procedure can be implemented via the communication protocols DUST1 or SINEC H1 All utility download activities are controlled via job requests that arrive via its data interface corresponds to the CTS and US connector specifications The data to be loaded is also transmitted via this interface The download utility is made available by the function block LPN This block musttherefore be configured on each processor upon which its memory board is to be loaded on line 23 1 Hardware AllRAM memory modules MS55 and Flash memory modules MS5 from release B coding 81133 20 on the side of the board can be loaded Older releases of the MS5 modules coding 81113 20 or 81123 20 on the side of the board cannot be loaded via a download procedure They must be programmed off line The reason for this is that Flash modules must first be deleted before they can be loaded The delete process must be implemented block by block for the download procedure only possible from the release status B Due to this additional delete process the loading time for a Flash module takes cor
3. a maximum of 2ms is reserved for the download utility Maximum system loading 2ms 16ms 0 125 12 5 The LPN block normally processes one job request per clock period This signifies for loading that a loading telegram is received programmed in the memory board and a reply telegram returned per clock period If the reserved processing time is not completely utilized since for example no job request for processing has been made then itis made available to the system Therefore when no download procedure takes place then this system loading does not occur The loading procedure into RAM modules MS55 utilizes only a fraction of the maximum processing time of 2ms lt 0 1ms whereas writing to Flash EPROM MS5 will require programming times of 1 2ms for a loading telegram This must be taken into account for the loading procedure in order not to overload the processor 23 2 Release 04 96 Siemens AG 465 980 7107 22 SIMADYN D Configuring Manual Communication 23 Download 23 4 Response to Faults A differentiation into two cases is made when a fault occurs The block terminates a currently running download procedure it is set to the status OFF and additionally generates a communication error multiple configuring communication error The block terminates only the current download procedure with a corresponding error message i e memory board write protected write error etc at the shell error window in basic dialog and is reset
