Hello mattijsstu, if the PC has more then one network-adapters, see manual "SIMATIC HMI WinCC V7.5 SP1 WinCC Information System" https://support.industry.siemens.com/cs/ww/en/view/109772961/125855967499 It is important that the Multicast-Telegrams are not Regards Georg Berghof |

Hello I had a similar problem with the visibility of some WinCC PCs on Simatic Shell. In my case, I had 2 ESXi hosts (VMware7.0) connected to an Extreme X620 switch via an FO patch cord. This connection was a trunk because I had 4 Vlans (HMI, PLC, ThinClient, Mgmt). HMI Vlan was not the Default vlan. On ESXi1 I had (Server1, Client1, Client2), on ESXi 2 I had (Server2, Client3, Client4, Client5). Each VM had 4 ethernet cards and a configured IPv4 address from different subnets. For example, Server 1 on the first ehernet adapter (HMI Vlan) had the IPv4 address 192.168.120.10 Simatic Shell - Communication Settings - Network adapter Selection - has been configured on the Ethernet HMI adapter. When I opened the Simatic Shell window on server 1, I only saw the VMs which was powered on ESXi1, and on ESXi2 I had a similar situation. Server 1 couldn't see Server 2 on Simatic Shell and vice versa but I was able to transfer files between them and ping by name and everything worked except these-(Simatic Shell) I used all the suggestions described in the FAQ: https://support.industry.siemens.com/cs/ww/en/view/868014 https://support.industry.siemens.com/cs/ww/en/view/25437381 https://support.industry.siemens.com/cs/de/en/view/18967416 https://support.industry.siemens.com/cs/ww/en/view/109772961/125855967499 and nothing, the servers still couldn't see each other in Simatic Shell. Later I became interested in multicast communication between Windows CCAgent processes Then I executed the commands below on the switch: show mcast cache show mcast ipv4 cache vlan HMI show igmp snooping HMI Next then I made sure my HMI vlan was enabled IGMP and IGMP Snooping at the vlan level, Finally I realized that when I was creating the HMI vlan, I forgot to configure the ipaddress on the HMI vlan I ececuted the command configure vlan HMI ipaddress 192.168.120.1 /24 and that's what was missing. After that all servers and clients were visible in Simatic Shell. Perhaps my case will be helpful to you. Best regards. |
