Find technical answers by protocol, product and application.
I/O requirements select DDC products unless a physical touchscreen is requested; touchscreen models must then satisfy the specified I/O counts as well.
Use the complete model and its 2026 document. HMI1002-Lite-E and BAC1002-Lite-E do not share the same documented acquisition scope.
Check physical interfaces, protocol support and shared-port arrangements separately, especially native two-wire MBus versus four-wire devices connected through RS485.
Multiple protocols require an AND match. Manual names are kept exactly, and undocumented compatibility is never treated as confirmed support.
X denotes the acquisition-side protocols. Also check forwarding protocols, communication roles, physical interface types and port counts.
