Connection of redundant I/O devices to S7-1500

  • Entry
  • Associated product(s)
Here you find a way to connect redundant I/O devices to a S7-1500 controller. For this solution you can use blocks of the TIA Portal.

The following example uses a CPU S7-1517H and a ET 200SP. Generally you can use the function blocks with other S7-1500 controller and other I/O devices.

Standard I/Os can only be used for module-specific redundant circuits. For channel-specific circuits you have to use high feature modules!
