IEC 60870-5 Client
An IEC 60870-5 Client is a communication component in a SCADA or automation system that initiates and manages data exchange with remote devices using the IEC 60870-5 telecontrol protocol IEC 60870-5-104 (TCP/IP). Note: IEC 60870-5-101 (serial) is not currently supported.

IEC 60870-5 Server
An IEC 60870-5 Server is a communication component implemented in field devices—such as RTUs, substations, protection relays, and data concentrators—that responds to requests from an IEC 60870-5 Client and provides real-time data, events, and control interfaces. It implements the server-side (outstation) role defined by the IEC 60870-5 telecontrol standards, including IEC 60870-5-101 for serial communication and IEC 60870-5-104 for TCP/IP networks.
IEC 60870-5 Server information objects
If the device doesn't have the needed capabilities for a specic information object, then that object won't exist.
If an error occurs while reading an information object:
- For a M_IT_NA_1, then the value will be 0 and the invalid ag will be set
- All other types, then the value will be 0 and the invalid and substituted quality bit will be set
