The machines I was concerned about, as far as operating overseas, turned out to not be a problem, but some of the auxillary equipment is.

What I am having a current issue with is the UV (ultraviolet) dryers. I'll explain what I have and what I need.

The first one operates four lamp heads. It uses a Mitsubishi FX2N-64MR-ES/UL PLC and two FX0N-8EYR-ES/UL I/O modules and FX0N-3A analog input module. It looks like it is also supposed to have a F940GOT HMI to control it, but it is missing.

The other unit has eight lamp heads, two control cabinets, each with its own PLC, in a master/slave arrangement linked by RS-422 or RS-485, but for the time being I won't get into that. But that one DOES have the HMI.

I am not opposed to changing the PLC - for what I am doing I'm sure the Click has plenty of capability and program space, and the 6 " C-More Micro Touch should be a fine HMI to work with it. My problem is trying to lift the existing program from the Mitsubishi PLC. We have other UV dryers here, but the way these operate is completely different than how our other ones work. Our others don't use PLCs, just relatively simple switch and relay logic. These have dozens of relays and PLCs to drive them. The manufacturer is still in business - but they are more interested in selling us new units - "These weren't designed for the USA, they are designed for Europe, they won't work on your power, they are 18 years old and obsolete, why don't you just buy new ones? "

I can tell you that there is no way we are going to spend upwards of $150K to replace these with newer ones, especially when we spent less than that for ALL the equipment - two presses and lots of accessories. They are not at all being helpful. I can't even get an operating manual or PLC programs, although I do have schematics.

I do have a cable that went to the missing HMI - on one end it has the special connector for the programming port on the PLC, on the other end it has a connector for the HMI. The HMI has two ports, the other I *think* is an RS-232 port for programming.

Initially, I would like to set this up so that one control cabinet can service two machines, with one lamp on each machine. In order for that to work I have to have to PLC respond differently depending on what each press is doing. It doesn't matter if I can change to program in the Mitsubishi, if I can read it that would be enough to write a program for a Click.

Also, the F940GOT HMI operates on 24 volts DC - is it compatible with the Click! PLC?

IF you know how the machine worked with the Mitsubishi PLC's, you could just write the Click program from scratch. The HMI is another issue; does it have the Click drivers for communication? If not, you'll have to replace with a C-more

Like I said, it is built differently and functions differently from our other machines. I don't know exactly HOW it is supposed to function.

There are three distinct phases to the operation of the lamp: Warmup, Idle and Run. Our existing ones use a large and very heavy transformer with a high open circuit voltage, these run off the line and have an ignitor to strike the lamp. Our existing ones start at medium during warmup, then go to low at idle; for run it goes to whatever the operator selects (and that may be based on machine speed as well). They may or may not operate the exhaust during warmup, although it MUST be on during idle and run. I'm pretty sure run is the same, but I do not know if the exhaust is enabled during warmup, which of the five levels are used during warmup or idle. There is a lamp current sensor which operates a relay that goes to a PLC input, but I am not sure if it is to merely signal that the lamp is running, or it could be set to a point where when the lamp current drops as the lamp warms up it shows that it is ready.

I'm going to try connecting it with what I 've got and see if I can determine its operating sequence.

references MEMOBUS between GOT-F900 and CP-217F

This THREAD at another forum discusses MEMOBUS compared to Modbus.

The three replies lead me to believe that MEMOBUS is an extension of Modbus and is !backward! compatible with Modbus.

Hope this gives encouragement to continue. If all this fails to live up to the description, JUST C-MORE IT!
