MicroLogix 1200--where is the programming port

[Skidood]

Hi, The MicroLogix 1200 has a Com 0 port and a "HMI/programming port". When looking at the PLC, there is a port on the left side and a port on top (on the front face). Which one is which? This is not addressed in the manual and I don't have one here to look at. Thank you!

Look at the Manual located here. It shows the difference.

I have the manual...not the PLC...the manual does not clearly indicate which is which. Although if I had to bet money on it, I would guess the Com 0 is the one facing up and the programming port is on the side.

Specifically, page 1-1
You are right that the one on the side is programming.

Not all ML1200's have the side port only the ones with and R on the end of their part number have 2 ports.

All ML's use the Mini8DIN for programming. It also can be used for a HMI.


I was called to a shop where their guy [Bubba] was suspecting the port had failed because RSLinx DF-1 could not connect to it. A quick check where the Mini8DIN cable plugged in it already went and see it went to a PanelView 550 - K5, which is DH485 ONLY, so the port was changed.

Awesome thanks...I'm an idiot for missing that page when I checked the manual
