Thanks, the problem is that Wartsila is paranoid with potection. Do u know if thw WAN port in a FW can be used to connect aother LAN. i.e is te WAN port just another ethernet port or is it especial and only DSL line can be conencted to it.

I am trying to get them off their booty and have a look it. Just one question, since u seem to know quite more than myself about entworks, how would u go about installing/configuring so that Wartsila is proteced from lets say LAN A, FW? Router? thanks

exactly the connection is failing a fair bit and i have the feeling its the way the physical connections are made. I am sure the FW is in the worng place, cause if i was to find out their local ip addresess i will be able to get all the data i want since the FW is behind their switch.Do u know people from Wartsila?

Wartsila also uses Intouch and it is no vessel, its a 32 MW cogeneration plant in madrid new airport terminal. Wartsila is afraid of having thei system compromised thats the reason for their. I am no expert in comms but as far as i know they have configured in the FW an IP from our LAN IP range to allow us acces to the intouch variables. Not sure if it makes sense. thanks

Thanks for the prompt response, Both SCADA are Intouch systems LAN B is a SCADA from Wartsila (Finnish engine supplier) so they set it up so that we could only read certain variables from their engines into another SCADA. I also cannot undertand why the FW is not between both LANs. The data is being passed through, however the communication cuts out very often. not only that but the other day someone connected another ethernet cable between the FW and the switch and all PLCs in the plant went into stop mode, it caused an illegal loop but even Siemens (they are S7 PLCs) cant work it out why this cable caused this havoc.

Hi, Iwas wondering if anyone can tell me how to place a Firewall between 2 different SCADAs, i.e 2 different private networks. The idea is that only certain data is read from one SCADA to the other. Currently the firewall is connected behid the switch from one of the LANs and not in between. Basically a LAN B cable is connected to the WAN port of the FW an another cabel from the LAN B switch to the FW, and finally another cable joining both switches from LANA and LANB. Attached is a diagram showing the connections. thanks in advance.

Hi, I want to install an extra termianl where the operator can only view and not control anyhtiung at all for an intouch SCADA system. I want to know if i need to buy a factory focus licence in order to display screens or is there another way possible? Thanks
