If it is only the acknowledgment of 2 alarms in the 4 LOGO!s, you can send only to one LOGO! from the HMI. Then send the two acknowledgment bits by using the VM range from the HMI to the first LOGO! and this then forwards the bits to the other 3 LOGO!s. Or you take an HMI, which can manage at least 4 connections and sends the acknowledgment bits by using of the VM range from the HMI to each LOGO!.

qwemx Posts: 364 Rating: (6)	ixo65 New name, new avatar .... all very nice. But also something new on the topic? Did you solved your problem? i am now thinking to go for S7-1200 controller . I have asked the local Siemens guy to help me with this , i sent him email today he said that he will respond back meanwhile i also got an email from Siemens from support request. It says :- Dear Sir/Madam, It is possible to connect multiple logo controllers to an HMI panel for sure. However, it is restricted by a couple of factors: ·Type of connection used i.e. PPI or MPI or Ethernet ·Series of HMI panel used, which limits the number of connections ·Software used to configure the HMI panel e.g. Protool or WinCC flexible or WinCC TIA portal. I need to make this decision if i go with logo or S7-1200 and seeing that there could be some limitations i want to use s7-1200 Logo will be cheaper it might be more difficult to connect logo to other logo and HMI i am also working on HMI design and programming with TIA for 1200 .
