Siemens Simatic Net
Siemens Communication is a plug-in or stand-alone link you choose to tie networks together: select CP 343-1, CM 1241, SCALANCE XC or S615, clip on DIN rail or insert in rack; copper, fiber, WLAN or 5 GHz private, supporting OPC UA, MQTT, NAT, firewall and VPN, so data flows from sensor to cloud without gateways and you keep one engineering tool for diagnostics across the plant.
