The 6ES7341-1CH00-0AE0: The RS422/485 interface supports multi-drop (up to 32 nodes on RS485) and longer cable runs than RS232 — useful when the serial device sits across the plant floor from the panel.
EOL — plan your next move
For a line-down replacement or a new build, you will need to identify a current serial communication module that fits the S7-300 backplane — or plan a migration path if the rack itself is also aging.
Sourcing reality for the 6ES7341-1CH00-0AE0
Because this module is EOL, availability is intermittent. We source it through independent distribution channels and quote each request against the specific BOM quantity.
