JSON-RPC proxy for talking Modbus over RTU and TCP.

Project Description


Tolk exposes a JSON-RPC API to talk Modbus over RTU or TCP and is written in Python. The source can be found on GitHub. Documentation is available at Read the Docs.


Below you can find sample code how to start Tolk listening at a Unix Domain Socket for JSON-RPC request. Tolk will delegate the requests via the Dispatcher to the modbus_tk.modbus_tcp.TcpMaster which in turn will request a Modbus slave at localhost:502.

from modbus_tk.modbus_tcp import TcpMaster
from SocketServer import UnixStreamServer

from tolk import Dispatcher, Handler

# The TcpMaster will fire requests to a Modbus slave at localhost:502.
modbus_master = TcpMaster('localhost', 502)
dispatcher = Dispatcher(modbus_master)

server = UnixStreamServer('/tmp/tolk.sock', Handler)
server.dispatcher = dispatcher
