I am new to PLC and have just bought a SLC500 L542 system with power supply and 10 racks 7 of which are filled, 3 are empty.
I am a little disappointed to see that this unit doesn't have ethernet capability. So now looking for a economical solution. What kind of module can I buy to give this rack ethernet capable? How much am I looking to spend?
I would appreciate if you tell me the module model number too if possible. eg. 1747-XXX etc thanks
