How to connect to JZ10-R16, MFG-Code: M80-P1


Recommended Posts

Hey guys,

We have a very old compressor from a turkish company that used this HMI to control it, the problem is that now we want to modify something and I can't figure out the way to connect to the plc. 

There are 10 pins on the communication port and I want to connect with RS232, I am guessing that this is a very old PLC model: JZ10-R16, MFG. CODE: M80-P1

I found a pinout here https://unitronicsplc.com/Download/SoftwareHelp/U90LadderKnowledgebase/Communications/Direct_Communications-_PC_to_PLC.htm but this only describes 6 pins and mine has 10 pins. Where can I find the correct pinout for my model? I also tried looking in the help menu of VisiLogic but could not find it there.

Best Regards,

Tod

I tried to research this port and the original programming adapter for my own needs.
Making your own is probably possible (and I even managed to do it with the USB interface- on foto),

but there are two major problems - there is a 3.3 volt communication port in the PLC that requires a mandatory galvanic isolation that is in the original adapter.

Therefore, I recommend listening to the above.
You should use the standard devices listed in the topic for programming this PLC.

so it is not possible to connect to the controller without special connector

No. 

One way they made the Jazz lower cost was to eliminate the TTL-RS232 converter chip and circuitry.  The target for this product is OEMs, and if you know anything about dealing with that market they value low cost almost above all else.

A JZ10-16 is not that terribly old.  I have a couple in stock.

You don't mention what part of the world you're in, but a JZ-PRG programming port is $47.00 US.

P.S. - @kratmel - you are hardcore indeed.  That looks like a hackulation I would try to build to save a nickel.  The mega heatshrink is a nice touch.  😁

Thank you Joe!   :)

is used for isolate board and fit board to Jazz PRG dimention.

You won't believe it, but a broken arduino + chip for correct galvanic isolation works as a programmer or PC232 port.

The main task was to create a CNC machine based on Jazz and the free Arduino GRBL CNC conrtoller based on a stepper motor.

It installed to Jazz like JazzPRG.
It had to perform only two standard movements but with a complex 2D trajectory.

Everything works ...  Jazz 10 replace original old puter and ISA CNC card in it!
