signal modules
Profibus DP Cable
Module
For this example, you need the following hardware components:
• A programmable logic controller consisting of:
- 1 mounting rack (UR2-H)
- 1 power supply (PS 407 10A)
- 1 CPU 417-4H
• An ET 200M distributed I/O device with an active backplane bus consisting of:
- 1 power supply (PS307 5A)
- 1 IM 153-2 Bus Interface Module
- 1 Safety Protector Module
- 1 fail-safe digital input module (SM 326F DI 24xDC24V)
- 1 fail-safe digital output module (SM 326F DO10xDC24V/2A)
• Other accessories
- PROFIBUS cables and connectors
Set the DIL switches for the individual components as follows:
• IM153-2 PROFIBUS address 3
• SM 326F DI 24 Module address 8
(Only found on the reverse side; only in steps of 8)
• SM 326F DO10 Module address 24
(Only found on the reverse side; only in steps of 8)
