Details: Is it possible to establish communication between CPU 414-4H and CPU412-3H system directly via profibus. where the profibus port of one 414-4H system CPU is connected to the profibus port of 412-3H CPU via profibus?? Do we need any CP 443-5 Ext or we can directly use the DP ports of the CPUs? Please help on an urgent basis..I am attaching the Automation Configuration.

Hello, Have a look to the manual: http://support.automation.siemens.com/WW/view/en/1186523 Chapter 11 of that manual describes the communication for a H-system. Annex E shows youthe supported CPs. For the number of CPs andfurther HW needed,you will have to decide if you want to have the communication fault-tolerant or not, how far you want the redundandancy to reach. You require a suitable CP for fault-tolerant S7 connections via PROFIBUS. These connections are not possible via the internal PROFIBUS-DP interface. (p.168 of the manual). |
