Hi Niklas_MC if we stick with Siemens speak, there's two I/O device related features to be aware off when it comes to using them with a H System: S2: System redundancy. This allows the I/O Device to have an application and communication relationship with both I/O controller. This is required so that if one CPU goes down, the partner CPU can seamlessly take over control of the I/O device and there's a number of I/O devices on offer from Siemens that support this (e.g. ET200M, ET200SP, a few SINAMICS CU's, SIMOCODE etc.) R1: Redundant Profinet. This describes an I/O Device that does have two physically independent Profinet Interfaces and thus caters for the connection to a H system via physically redundant Profinet cabling. At this stage, only the ET200SP HA caters for this. Have a look too at the two links below for more (generally applicable, even though it has PCS7 in the name): |

Niklas, You it is no possible to assigned one Device for 2 normal PLCs (not H systems), this is not because Siemens dont have this technology, its because how Profinet works. Even though, some devices have this functionality: https://support.industry.siemens.com/cs/ww/en/view/109741600 Shared Devices fucntionality is not redundancy, but with this you can shared IO from one IM. But we need to remember that not all devices have this functionality. If you want to have PLC redundancy, the only possible way to archive that is using special devices prepared for that: Regards, Online_Diagnostics |
