Introduction

This software provides an object-oriented high-level python module to simulate scada systems and remote terminal units communicating via 60870-5-104 protocol.

The python module c104 combines the use of lib60870-C with state structures and python callback handlers.

Example remote terminal unit

import c104

# server and station preparation
server = c104.Server(ip="0.0.0.0", port=2404)

# add local station and points
station = server.add_station(common_address=47)
measurement_point = station.add_point(io_address=11, type=c104.Type.M_ME_NC_1, report_ms=1000)
command_point = station.add_point(io_address=12, type=c104.Type.C_RC_TA_1)

server.start()

Example scada unit

import c104

client = c104.Client(tick_rate_ms=1000, command_timeout_ms=5000)

# add RTU with station and points
connection = client.add_connection(ip="127.0.0.1", port=2404, init=c104.Init.INTERROGATION)
station = connection.add_station(common_address=47)
measurement_point = station.add_point(io_address=11, type=c104.Type.M_ME_NC_1, report_ms=1000)
command_point = station.add_point(io_address=12, type=c104.Type.C_RC_TA_1)

client.start()
