On page 29 of the documentation for the IM155 ( https://support.industry.siemens.com/cs/ww/en/view/59768173 ) it shows the status LED text description. What status is your IM155 showing? Is it showing just the ER (Red) flashing? Page 29 describes the problem and remedy. I would suspect you wired them up expecting everything to work without enabling and forcing the PLC to auto-configure attached hardware (I do not enable the plc to auto-configure either). If you use the online access in your project tree (below your PLC and IM155), and double click on the LAN adapter you are using, all Siemens devices should show up. The IM155 should appear in the list of devices. If it has a different name than what you named it in your project, you need to use portal to assign the name. Same goes for the ip address. When you double-click on the IM155 (make sure it is the one you are having trouble with by comparing mac addresses, or making the LEDs flash -- use F1-help if you do not know what that means). Once the name and ip address are set via TIA portal, they should be able to communicate, depending on the configuration settings.
