text: <s>[INST] Can I replace an 1769 L36-ERM with an L36-ERMS?  Other than some additional memory, the specs appear the same. [/INST] Sure you can replace a 1769 L36-ERM with an ERMS no problem. There is extra Memory for the safety part, ... for the rest they looks the same (power is the same, supported module is the same...etc) You will have to change the controller in the application code.\n </s>
