Getting PointIO devices?

[13igred]

Hello,

Is it possible to get the module information of PointIO devices?

I have several PLCs with a lot of PointIO and I want to read for, example the revision number, part number, ect. Basically the same information you get when you do a get_module_info.

Yeah, unfortunately that method isn't very sophisticated and doesn't work for this. I plan on replacing it and adding a bunch more features to the CIPDriver, but until then you can do it but have to do it manually. Here is a small example that works, you can probably modify it to your needs:

from pycomm3 import CIPDriver, ModuleIdentityObject, ClassCode, Services

entrypoint = '10.1.128.45'
pointio_route = '1/1/2/192.168.1.41'

with CIPDriver(entrypoint) as plc:
    
    for slot in range(8):
        resp = plc.generic_message(
            service=Services.get_attributes_all,
            class_code=ClassCode.identity_object,
            instance=1,
            data_type=ModuleIdentityObject,
            route_path=f'{pointio_route}/1/{slot}',
            connected=False,
            unconnected_send=True,
        )
    
        print(f'{slot}: {resp.value["product_name"] if resp else "EMPTY"}'))

This is for a rack that's behind a controllogix chassis, if you can access your point io rack directly by IP, you should be able to omit the pointio_route and make your route_path just 1/{slot}.

Works like a charm, thanks and sorry for the late reply. I did not see the email.
