- Provides one RS485 or RS422 interface
- Network mode and communication frame are project-defined
- The interface is electrically isolated
7IF321.7 is a network-capable System 2003 screw-in interface module with one electrically isolated RS485/RS422 port.
It adds differential serial networking to a compatible System 2003 CPU for supported multidrop or point-to-point devices.
Before installation or replacement, verify the RS485 or RS422 mode, network topology, baud rate and frame, node addressing, termination and bias, connector pinout, shielding and ground reference.
Availability, condition, price, and shipping time for 7IF321.7 are confirmed during quotation.

- Provides one RS485 or RS422 interface
- Installs as a System 2003 screw-in module
- Supports network-capable differential serial communication
- Network mode and communication frame are project-defined
- Termination and bias must match the physical topology
- Node addressing must be unique where the selected protocol requires it
- The interface is electrically isolated
- Shield and protective-earth practice still require verification
- Isolation does not correct reversed data pairs or incorrect termination
- RS485 multidrop communication with supported industrial devices
- RS422 point-to-point differential serial links
- Electrically isolated serial networking for System 2003 machine-control stations
