Trying to read compactlogix l30er getting a CIP Error code port not available

[Buzznacker]

I am using libplctag 1.2.1

Trying to read a compactlogix l30er and I keep getting CIP Error code port not available. I've tried using Telnet on the 44818 port on the address of the PLC and I am able to successfully connect so I know the PLC is accessible.

var tag = new TagBool
{
    Gateway = ip,
    Path = "1,0",
    Name = tagName,
    Protocol = Protocol.ab_eip,
    PlcType = PlcType.ControlLogix,
    DebugLevel = DebugLevel.Detail
};

Try a path of "0,0". IIRC, that is correct for those PLCs. I do not have one to test on so I am not sure.

Thanks for your reply, I've tried this and still no changes still getting the CIP Error

Edit: I've tried the 0,0 1,0 2,0 3,0 4,0 all of these paths are not working

I used to use a similar model at a previous workplace and "1,0" was what I used.

Were you able to resolve this in the end?

Hi @Buzznacker - if this is still a problem, please let us know. Probably the main repo is the right place as this isn't a wrapper-specific problem.
