What kind of security measures can be taken for an ECOM/ECOM100 connected to the Internet?
There are no security measures built into the ECOM/ECOM100 to help with this. The Koyo PLCs have password protection (the DL205 family even has HMI level passwords), but once the PLC is unlocked, it is unlocked for anybody to access. Probably the best and easiest thing is to have your IT (Internet Technology) people set up a VPN (Virtual Private Network) so that only certain predetermined PCs can have access to the ECOM/ECOM100’s network.
