masimn Posts: 48 Rating: (0)	Hi All We have a equipment having S7 – 200 ( CPU 226 AC/DC/RLY) plc and HMI “TP 177”. Now due to some problem I have to change the power supply. The sales persons asking me about the SITOP or MODULAR. Can any body please help me in describing the difference between “SITOP” and “MODULAR” and what type to be use? In our panel the power supply is supplying power to the PLC, Analog input and output modules , TP 177 HMI.
