The IEC 60870-5-104 slave I/O interface allows exchanging data over TCP with any industrial devices and SCADA systems. Using a standard network interface card, this protocol can be easily and rapidly integrated into any simulation model. With the proper user configuration, a driver is initialized on the target simulator at the start of the simulation and waits for a (or many) master(s) to connect to each slave to begin data transmission. The driver makes use of asynchronous threads in order to service each slave. 

This driver provides an asynchronous TCP/IP communication interface and an IP aliasing mechanism allowing to assign different IP addresses to each slave/outstation instance even if a single physical network interface (i.e., ethernet port) is used.

IEC-60870-5-104 is an International Communications Protocol Standard for the telecontrol of electric power transmission systems. The standard specifies the use of permanent directly connected links between Telecontrol stations.

Platform Compatibility

Product Selection Guide

IEC 60870-5-104 Slave requires software license OP3241, which comes with 50 data points (Visit this website more information on data points). If additional data points are required, then they may be added via product OP3050. 

Since real-time simulators come with one available ethernet port, if additional physical ethernet ports are required on the real-time simulator, these can be added via kit. Note that for applications requiring many ethernet ports, the OP4510 platform is not recommended.
