  Информационные материалы

  • Drivers for Modbus protocol with RTU message format; communication as master or slave
  • Downloadable onto CP 341 and CP 441-2 (6ES7 441-2AA04-0AE0)

  Область применения

  Drivers are available for downloading for the CP 341 and CP 441-2:

  • Modbus:
    For communication according to the Modbus protocol with RTU format.
    Communication as master or slave

  The two serial interfaces of the CP 441-2 can be operated independently with different standard protocols or downloadable drivers together with the V.24/TTY/X.27 interface modules.

  Функции

  Modbus

  • Modbus master:
    Master/slave coupling with SIMATIC S7 as master.
  • Modbus slave:
    Master/slave coupling with SIMATIC S7 as slave, message frame traffic from slave to slave not possible.

  Configuration

  The configuration package for CP 441-2 and CP 341 (V4.0 and higher) and STEP 7 V4.0 are required for downloading and configuration of the drivers. The drivers are copy protected by a dongle.
