I have a water tank that I am needing to control a VFD output speed. I have the Scale block setup with a Max input of 25.0 feet. with "0" as monimum. I have the output set at a max of 4095 which translates to 60 Hz. I have a minimum of 30 Hz Now, for the issue, if set the tank pump to run "on" at 10' and off at 7', So it should be 60 Hz at 10 and slowing to 30 Hz at 7" (Yes sort of a mX+B scenario) I then do a MOV to send the 10' max to the Max input register like D7880. I can't get the Data register to be a solid Max at the needed 10.0. It flickers back and forth between 10.0 and 25.0 and AO is very erratic. I've tried to us the Float, and Word as the data types. I can make it all go with a lot of compares and moves (think FGEN) but would really like the Scale function to handle this, and just not familiar enough to how-to it.

OK, now I'm confused because your opening manual screenshots says "Modbus Registere". It also says to use Fiunction 16 for multiple registers. Sound a lot like Modbus to me. Please clarify which your using.

Set the DELTA to TCP/IP (5 Digits). Let us know.

What VFD brand? Usually the DB9 is for programming only. I'd think the RS485 and even the Ethernet are used for the application. The 232 is only reliable at about 3 meters(?),

Weintek HMI & IDEC PLC - Confused on how these tags are linked
a062549 replied to grubb's topic in Other PLCs
I'll gove my ideas, so here I go: It appears the Weintek is acting as a Modbus Master, and writing to the IDEC (in second pic) as 47652.00/ Read register 47652 Bit 0. Post here if the forum can provide more info -

I remember using the Kunlum as I used to live in China, For some reason it seems the Kunlun was using some sort of a knock-off Mitsubishi software, maybe? I know it used the same DB-9 to Mini DIN-8 connector. This is me trying to remember 15 years ago, but maybe worth a try? Followup: ENGLISH VERSION HMI MCGS PROGRAMMING SOFTWARE - YouTube Appears the MCGS now owns Kunlun?

The PI function is good for most applications, unless you need the derivative (Motion controls).

Hi Michael!
I assume you're still bailing the Hilcorp bunch out?
I did see a rumor they are going to buy the old P66 refinery in Louisiana? Are they nuts? Course it'll give you something to do for like 25 years.
Always good to hear for you.
Best, John

Thanks Michael! Never thought of using colors to explain it, Hope your warm and cozy with lights and water. -

Haven't looked for a RS232 one yet. -

http://dl.mitsubishielectric.com/dl/fa/document/manual/plc_fx/jy992d69901/jy992d69901e.pdf Appears the use of the M8000 is an issue as it never changes, so it sends the read cmd once. Use the M8123 register and it cycles to read the RTU info. -
I've looked at several supply houses and none of them have the FC6A version of this card in stock. Hmmm...
-
I've used the FC4A Analog module, on a FC6A, which they thankfully added a checkbox to help with the remapping of points. That noted, this is the basis which I am asking the question about the relay card. If they did the analog card, have they also made the other IO modules usable? I'll try it when I get back to the lab that doubles as my garage.

I'm integrating a small project using an IDEC FC6A-C24. I have a couple fo the IDEC FC4A-R081 relay modules laying around and wondering if the FC4A named module will work on the FC6A? I have one and have tried it but getting a bus error. Not sure if the relay card is good either, as it was rolling around in my travel box.
