  • Max. 32 bytes of input and output data per module
  • LED indicators
  • DIAG: Operating state indicator (green/red) of the module
  • C1..C4: Port status indicator (green) for Port 1, 2, 3 and 4
  • Q1..Q4: Channel status indicator (green) for Port 1, 2, 3 and 4
  • F1..F4: Port fault indicator (red) for Port 1, 2, 3 and 4
  • Depending on the CPU type used, as many as 8 SM 1278 modules can be used on one S7-1200 CPU.

The SM 1278 module enables data exchange with up to 4 external IO-Link devices via one 3-wire cable each or four standard actuators/standard sensors. Comprehensive parameterization options make it possible to adapt the controller flexibly to the communication partner. Thanks to the compatibility of IO-Link with standard sensors, commercially available sensors in accordance with IEC 61131 Type 1 can also be operated on the IO-Link master.
