connecting to a S7-200

[amarco]

I am trying to connect to S7-200.
I have the following snippet in python (using python-snap7 1.2 stable.

self.plc = snap7.client.Client() #create instance of client
self.plc.set_connection_params(ip, localtsap, remotetsap) #setup connection parameters
self.plc.connect() #try and connect

My problem is with the connect, it calls for using a ip address, slot and rack parameters which do not apply to the S7-200.

My question is how to connect to a device using the set_connection_params() method and not have the connect call require the restating of different connection parameters. I have not been able to find a connect option that would not take any parameters and use the info from the set_connection_params() call.

Hi Marco,

S7-200 is (normally) not in scope of snap7 since 2013.
Anyway you can try connection to it as a LOGO device.

No guaranty that this will work, but otherwise you may have to look for another library.
