F8627X vs F8627 (Core Differences)

F8627: Basic version, only supports SafeEthernet, OPC DA; Part Number 984862760

F8627X: Enhanced version, adds Modbus TCP, OPC A&E; Part Number 984862765; Fully compatible with F8627, can be directly replaced

Installation and Maintenance

Insert and lock the slot to ensure reliable connection of the backplane contacts

Connect Ethernet / HSR / Debug interfaces according to specifications, and ground the cabinet reliably

Check the status of indicator lights during daily inspections, regularly tighten terminals and clean dust

Direct replacement of the same model is allowed, no need to reconfigure programs and addresses
