Here is what I use to read online the parameter value. proj = projects.primary app = proj.active_application plc = proj.find("Device", True)[0] onlineapp = online.create_online_application(app) onlineapp.login(OnlineChangeOption.Try, True) dev1 = proj.find("DEV1", True)[0] for conn in dev1.connectors: > parms = conn.host_parameters > if len(parms) > 0: > p = parms.by_id(1074855985) > p.read_online_value(2000) ---> error: Gateway not configured properly Does anyone know about this?

Post by timvh on CODESYS: Combining Master Redundancy with EtherCAT Ring Topology – Is it Supported? ^{CODESYS Forge talk (Post)}
Yes, this works (at least we have it running with Wago PLC and Beckhoff I/O), but the concept works. You need 2 PLC's with at leat 3 network interfaces. And 2 switches (can be unmanaged). See the attached simple diagram for the solution.

I am experiencing quite high CPU load on My Schneider M241 PLC with WebVisu. I would like to know what is best practice and how you create your application with pages, frames, tags, dialogs and settings to make an efficient HMI with low CPU load. Thanks

in your project, to access /var/opt/codesys/PlcLogic/my.file, use the string 'my.file' or '$$PlcLogic$$/my.file'

In simulation mode there are no fieldbus updates possible - so this makes only sense with real devices.
