The C70 can specify a maximum of five clients for its IEC 104 connections. These are IP addresses for the controllers to
which the C70 can connect. A maximum of two simultaneous connections are supported at any given time.

The C70 is provided with optional IEC 60870-5-103 communications capability. This feature is specified as a
software option at the time of ordering. See the Order Codes section in chapter 2 for details.
IEC 60870-5-103 is a companion standard to the IEC 60870-5 suite of standards for transmission protocols. It defines
messages and procedures for interoperability between protection equipment and devices of a control system in a
substation for communicating on a serial line.
The IEC 60870-5-103 protocol is enabled when the
is set to IEC 60870-5-103.
The IEC 60870-5-103 is an unbalanced (master-slave) protocol for coded-bit serial communication, exchanging
information with a control system. In the context of this protocol, the protection equipment is the slave and the control
system is the master. The communication is based on a point-to-point principle. The master must be able to interpret the
IEC 60870-5-103 communication messages.
The UR implementation of IEC 60870-5-103 consists of the following functions:
• Report binary inputs
• Report analog values (measurands)
• Commands
• Time synchronization
The RS485 port supports IEC 60870-5-103.
The UR Family Communications Guide contains more information on the protocol.
IEC103 COMMON ADDRESS OF ASDU
254. This ID does not need to be in sequential order for all stations that communicate with a controller, but it is
recommended. Note that RS485 only allows a maximum of 32 slave stations on a communication line, so the entire range
of 254 addresses is never exhausted.
