37 Main driver system SL150

SL150 is a new generation of high power AC Alternating Frequency main transmission system of SIEMENS. the core unit is Simotion D445 (or D455) module and Sinamics CU320 module.

 

37.1 D445 Standard Ethernet UDP scheme

D445's own ethernet network port is used. CBE30 module isn't needed, see the 4.27 section for other details.

To avoid IO faults causing downtime when PDAServer is offline, add fault handling programs.

 

37.2 D445 Real time Ethernet Profinet master scheme

Concentrate the signals of CU320 and D445 into D445, they are collected at high speed through Profinet, in D445, you need to insert the "CBE30 PN IO" module as the Profinet master, PDAServer may be as multi Profinet slaves, Please refer to the 4.7 section. PDA reads the other slow signals by OPC mode.

A CP1616 slave station can be built in a D445 (PDAServer determines which D445 data comes from by MAC address), Most 128*11=1408 bytes can be collected, which is usually enough.

 

 

 

37.3 CU320

Each CU320 can collect 50 bytes, they are configured in Scout, 16 Boolean variables can form a word, modify parameter p8848 to change data update cycle to 1ms, please see the section 4.50 for other.

37.4 D445+CU320 comprehensive scheme


37.5 Interface module scheme

SL150 outputs the key variables to the PDAU interface module at high speed in the way of AO or DO(same as SIMADYN-D), after A/D conversion, it sends them high speed to PDA server in RT-Ethernet, the fastest sampling period is 0.2ms.
