Selection Guidelines
-
When to choose: Applications requiring high-density serial integration with expanded protocol support.
-
Serial Configuration: Configure port type, baud rate, parity, and protocol per port.
-
Protocol Conversion: Configure serial-to-Ethernet mapping in Toolbox ST.
-
High-Speed Mode: Enable for devices requiring >115.2 kbps.
-
IEC 60870-5-101: Configure for power utility communication.
-
Compatibility: Fits all Mark VIe VME64x racks. Requires ControlST v6.5 or higher.
Operational Precautions
-
Wiring: Follow GE wiring diagrams—correct polarity for RS-232/422/485.
-
Serial Configuration: Verify baud rate, parity, and stop bits match connected devices.
-
Protocol Testing: Test each serial port during commissioning.
-
Ethernet Configuration: Configure IP addresses before plant network connection.
-
LED Diagnostics: Green = normal; Amber = communication active; Red = fault.
-
Fault Log: Access 750-event log via Toolbox ST.
-
Hot-Swap: Remove/insert slowly under power.
-
Spare Stock: Maintain 1 spare per 3–4 racks.
-
Firmware Updates: Ensure the GE IS215ISBBH2A is in “standby” mode.
-
ESD: Handle by edges with grounded wrist strap.
