Handler¶

class secsgem.hsms.handler.HsmsHandler(address, port, active, session_id, name, event_handler=None, custom_connection_handler=None)[source]¶

Bases: secsgem.common.EventProducer

Baseclass for creating Host/Equipment models. This layer contains the HSMS functionality. Inherit from this class and override required functions.

Parameters:

address (string) – IP address of remote host
port (integer) – TCP port of remote host
active (boolean) – Is the connection active (True) or passive (False)
session_id (integer) – session / device ID to use for connection
name (string) – Name of the underlying configuration
event_handler (secsgem.common.EventHandler) – object for event handling
custom_connection_handler (secsgem.hsms.connections.HsmsMultiPassiveServer) – object for connection handling (ie multi server)

Example:

import secsgem

def onConnect(event, data):
    print "Connected"

client = secsgem.HsmsHandler("10.211.55.33", 5000, True, 0, "test", event_handler=secsgem.EventHandler(events={'hsms_connected': onConnect}))

client.enable()

time.sleep(3)

client.disable()
