This device is obsolete and quite rare. There were at least two other Interface units, either of which would work in place of the F2- 20GF1. They are F-LINK and A-LINK. As these are so rare, we will concentrate on the F2-20GF1 for this procedure.
Components Needed: 1) Programming Software: – MELSEC MEDOC 2) Interface (I/F) to connect to programming port on F / F1 / F2 3) Serial Protocol Converter – i.e. PCX-KIT1.
This kit from Mitsubishi Tech Support incorporates a connector (adapter) which: connects to the DB25 connector on top of the F2-20GF1, Converts the Serial Protocol from RS422 to RS232C, Provides Power (12VDC) to the Converter, And, Provides connection (DB9) to your computer.
PCX-KIT1 1) Remove the access cover on your Mitsubishi PLC.
Mount F2-20GF1 The F2-20GF1 mounts on the port (also used for hand-held programmer). The two blue connectors fit together, and the two sliders on each side of the F2-20GF1 hold the I/F securely to the PLC. Note the end of the F2-20GF1 is flush with the end of the PLC (mentioned just as an aid to positioning).
12VDC Power WAIT TO PLUG IT IN, BUT DONT FORGET TO…..
Connection… 1Install F2-20GF1 on PLC 2Slide tabs to secure I/F on PLC 3Connect cable to I/F 4Plug 12VDC Transformer into 120VAC source. 5Insure that connections are secure on electronics box (the actual I/F). 6Connect I/F to your PC COM Port.
Complete the Connection ! Your installation should like something like this…
Connect the Power ! Now is the right time to connect the 12VDC to the I/F…
F2-20GF1 in Action. Briefly, all the RED LEDs come on, then after the F2-20GF1 determines which unit to which it is connected, that LED comes on solid. In this case, the F1/F2 LED is lit.
Putting It All Together… Youve got MEDOC Running on your PC… Youve got the F2- 20GF1 and the PCX- KIT1 connected from the PC to the PLC… And youve remembered to plug in the 12VDC …
Now the hard part begins! We at Lighthouse PLCs, Inc. hope you will benefit from this tutorial/primer. Communications with the older Mitsubishi (as well as other brand) PLCs is rapidly becoming a lost art. And, relevant manuals and documentation are becoming as rare as the PLCs themselves.
