We've been getting a huge number of hits to the new website by a number of companies across the world. We've also been getting a lot of interest in when more drivers will be available, like Siemens, Modbus, and Automation Direct in addition to the existing Allen Bradley suite. I suppose this isn't surprising considering that we're the only cross-platform OPC-UA server available. While it shouldn't be too long before we get those drivers developed, this brings me to my next point...
Where are the other OPC-UA servers? We're really looking forward to a more vibrant marketplace for OPC-UA products. Kepware says they'll be releasing their OPC-UA server soon - we're looking forward to being able to test it with Ignition. This really excites me because it brings their extensive PLC product line to the table via OPC-UA. Unfortunately, I don't think it will be cross platform.
So, how about it? OPC vendors: the gauntlet has been thrown. The industry wants OPC-UA products! And if they're cross platform, all the better. When will we start seeing them?
It's 2010 - many systems end up touching the Internet or outside world somehow, whether you like it or not. Common practices in the 90s, like allowing users to share passwords are unacceptable - that audit trail is a must. Having PLCs on the same network as office computers - professionally irresponsible. Your company uses 25 year old hardware that was never designed for security - it's up to you to isolate that network. Provide access with a "hardened" dual-homed (2 network cards) computer that is patched and protected by a firewall. Utilize VPNs, DMZs, VLANs, SSL, IDSs, and anything else in your IT department's arsenal. They know how to secure a network - it's their job. Gone are the days of operating behind their back, not letting them touch anything for fear that updates will break your system. Pick a vendor that IT will support. Practice Defense in Depth. Let them help you. It's 2010. Embrace positive change!
