MITSUBISHI F F 1 F 2 Serial Communications

MITSUBISHI F / F 1 / F 2 Serial Communications Procedure for connecting PLC to PC Requires: F 2 -20 F 1 & PCX-KIT 1 And MELSEC MEDOC® Click to Begin Presentation….

Components Needed: • Programming Software for PC – – MELSEC MEDOC

MEDOC Programming Software • Insure that MELSEC MEDOC has been installed on your laptop or desktop PC. When started, the initial screen should appear like this:

Components Needed: • 1) Programming Software: – MELSEC MEDOC • 2) Interface (I/F) to connect to programming port on F / F 1 / F 2

F 2 -20 GF 1 I/F

F 2 -20 GF 1 I/F

F 2 -20 GF 1 I/F This device is obsolete and quite rare. There were at least two other Interface units, either of which would work in place of the F 220 GF 1. They are F-LINK and A-LINK. As these are so rare, we will concentrate on the F 2 -20 GF 1 for this procedure.

Components Needed: • 1) Programming Software: – MELSEC MEDOC • 2) Interface (I/F) to connect to programming port on F / F 1 / F 2 • 3) Serial Protocol Converter – i. e. PCX-KIT 1.

PCX-KIT 1

PCX-KIT 1

PCX-KIT 1 This kit from Mitsubishi Tech Support incorporates a connector (adapter) which: connects to the DB 25 connector on top of the F 2 -20 GF 1, Converts the Serial Protocol from RS 422 to RS 232 C, Provides Power (12 VDC) to the Converter, And, Provides connection (DB 9) to your computer.

PCX-KIT 1 • 1) Remove the access cover on your Mitsubishi PLC.

Mount F 2 -20 GF 1 • The F 2 -20 GF 1 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 F 2 -20 GF 1 hold the I/F securely to the PLC. • Note the end of the F 2 -20 GF 1 is flush with the end of the PLC (mentioned just as an aid to positioning).

F 2 -20 GF 1 Mounting

F 2 -20 GF 1 NOTE That the DIP switches are set to 19. 2 K BAUD. The setting of this DIP switch should agree with the BAUD rate you choose in MEDOC (Transfer) Setup!!!

Connection… • 1 Install F 2 -20 GF 1 on PLC • 2 Slide “tabs” to secure I/F on PLC • 3 Connect cable to I/F

What We Have So Far…

12 VDC Power WAIT TO PLUG IT IN, BUT DON’T FORGET TO…. .

Connection… • • 1 Install F 2 -20 GF 1 on PLC 2 Slide “tabs” to secure I/F on PLC 3 Connect cable to I/F 4 Plug 12 VDC Transformer into 120 VAC source. • 5 Insure that connections are secure on “electronics box” (the actual I/F). • 6 Connect 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 12 VDC to the I/F…

F 2 -20 GF 1 in Action. Briefly, all the RED LEDs come on, then after the F 2 -20 GF 1 determines which unit to which it is connected, that LED comes on solid. In this case, the F 1/F 2 LED is lit.

Putting It All Together… • You’ve got MEDOC Running on your PC… • You’ve got the F 220 GF 1 and the PCXKIT 1 connected from the PC to the PLC… • And you’ve remembered to plug in the 12 VDC …

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.
