micrologix 1500 and RSLinx communication error
(OP)
When I try to communicate with the micrologix 1500 I get an error "unable to verify settings due to packet timeout in rslinx". I am using the right COM port, the plc is on and I am using a RS-232 DF1 device in RSLinx. However, I am using a usb-serial converter on my notebook. Anybody have any suggestions?

Another thing to try is to reset the coms to the default. Open the door where the battery is. near the side where the status lights are, you will see a small button labeled DCOM. Press this button until the status light "DCOM" lights. This will set port zero (round connector) to the default settings. Should be 9600 8N1. Also sets the protocol to DF-1 point to point. The protocol on the M1500 prorts can be set to something other than DF-1 (for example Modbus RTU).

RLGAuto.

You must see "Auto Configure successful" to know you are connected properly.
I had a similar problem a while back and I found it defaulted to COM4.
