Description

A proposito di questo prodotto

Ecco tutto quello che c'è da sapere


With its high speed processing (arithmetic operations, closed loop control) and high speed binary processing (logic control), the Siemens 6ES5 928-3UA21 is perfect for mid range applications.

The module offers the following:

  • Microprocessor (ASIC) for processing binary statements of a number of selected word statements
  • Microprocessor (16 bit) for processing word statements and the operating program of the module
  • Microprocessor (8 bit) for processing the programming device port
  • Memory (RAM) for bit memories, timers, counters, process image etc
  • Internal memory: 64Kbytes for user program and 46 Knytes (RAM) for data of the user program (data blocks)
  • Receptacle for SIMATIC memory card (Flash EPROM) for max 64 Kbytes user program. STEP 5 V5.6 and higher is required for programming and erasing the memory card
  • Programming device port (15 way cannon socket)
  • Shift register (246 x 8 bit) wuth high processing speed
  • Operating program for cyclic time and process controlled processing and error handling
  • Software for multiprocessor communication
  • Closed loop control algorithim 
  • Up to 4 x 6ES5928-3UA21 can be used in the central controller of the S5-135U or S5-155U PLC, which are suitable for multiprocessor operation with the following CPU; CPU 948, 928B, CPU 928
Restart Modes
Cold Restat with reset manualAll bit memories, timers and counters are reset and the process image erased. Scanning of the user program starts at the beginning
Warm restart, manualThe bit memories, timer, counters and the process image are retained during the down time. Scanning of the user program continues at the point of interuption
Warm restart, automaticFollowing power recovery, the PLC automatically enters the RUN mode. The other data is as listed under warm restart manual
Overall resetAll memory areas are erased. The PLC enters the basic state. If a rAM is ued, the user program must be loaded. If an EPROM is used a cold restart with reset is possible. The overall reset function can be tiggered by a switch on the processor or from the programming device.
Automation RestartAfter volate recovery the CPU returns automatically to the operating state. The other data is as listed under cold restart with reset manual. *The following start-up is only possible if block DX 0 is programmed accordingly.
