2.3.2 Configuring the Fault-Tolerant S7 FH System
Proceed in the same way as when you configure the S7 F Systems. You create a
new project in SIMATIC Manager for the hardware setup described above.
Procedure
1. Create a new project called "FHProject".
2. Insert a new SIMATIC H Station.
3. Open the hardware configuration of the SIMATIC H station(1).
4. Begin by placing the UR2-H mounting rack.
5. Insert the standard power supply (PS 407 10 A) in slot 1.
6. Place the CPU 417-4H V3.1 in slot 3 and create a subnet.
Insert two synchronization modules (H Sync module) at IF1 and IF2.
7. Open the properties dialog box of the CPU, enter a password for the CPU on
the "Protection" tab, and select the "CPU Contains Safety Program" check box.
8. Duplicate the entire mounting rack, and connect the CPU to a second
PROFIBUS subnet.
9. Add the IM 153-2 directly onto one of the two PROFIBUS subnets, and enter
the address 3: The ET 200M is connected to both subnets automatically.
(There is a "Redundancy" tab in the properties dialog box of the ET 200M.)
