It is not required to have H system for CiR, standard S7-400 CPUssupport CiR. It lloks likeCiR also supportsthird party devices. Check the link below. |

Hello Saren; If your question is: Is it possible to use a redundant CPu pair to ensure correct and seamless download of hardware configuration dwithout astopping runtime?", the yes it is. An expensive solution if that is your only reason to go that way, but it is possible. Have a look at the following extract: System modifications in operation14.2 Possible hardware modifications S7-400H14.2 Possible hardware modifications How is a hardware modification made? If the hardware components concerned are suitable for unplugging or plugging in live, the hardware modification can be carried out in the redundant state. However, the fault-tolerant system must be operated temporarily in single mode, because any download of new hardware configuration data in redundant mode would inevitably cause it to STOP. The process is then controlled only by one CPU, while you can carry out the relevant changes at the partner CPU. WARNING During a hardware modification, you can either remove or add modules. If you want to alter your fault-tolerant system in such a that you remove some modules and add others, you have to make two hardware changes. NOTICE Always download configuration changes to the CPU using the "Configure hardware" function. You can find more information on the required procedure in the manual “Fault-tolerant Systems S7-400H”: http://support.automation.siemens.com/WW/view/en/1186523 Hope this helps, Daniel Chartier |
