Hey Theo, Did you check D9008 - "Self Diagnosis Error"? It stores the error data until you either reset it in the program or turn the key on the PLC to Reset position. -Vasa

Ethernet communication of Q03UDE CPU and MT8104iH HMI
Vasa replied to atiqur36eee's topic in Mitsubishi
Hey atiqur, Maybe you just need to setup IP address and subnet mask in teh HMI properly (either done in HMI software or in the offline menu, never worked with Weinview). Default IP address for Q-series is 192.168.3.39, so if you set your HMI to something like 192.168.3.50 and subnet mask to 255.255.255.0 they should communicate. -Stan -
Ok the other version of the function would be: MOV K1 to some register (D0 for example) So, MOV K1 D0 TO H# K35 D0 K1 # being the position of the motion module on the rack. You can use Pulse version of the functions, MOVP, TOP. If it doesn't work, please get back to us.

Hey Sabbir, I looked at the manual for the QD75MH1, it looks like forced stop is parameter 82 and it says you need to write 1 to buffer memory location 35. So try this function: MOV K1 U#\G35 Replace the # with the number of the slot on the rack that your motion module is occupying. If this doesn't work, you might need to use the older version of the command - I forgot the format though, I'll look it up and get back to you.

Make sure you've selected the correct PLC type, some PLC models don't have USB, so it does not show up.

Hey Bill, I've also worked for a Japanese company and I know exactly what you are talking about. It is actually the PVC tubing that you can buy in a roll from Brady for example: http://www.bradyid.com/bradyid/pdpv/PVC-9.html The printer I've seen being used to print on these was a Brady91, apparently sold only in the Asian market - http://www.bradyid.com.sg/en-sg/bmp91-tube-label-printer--/fam-BRSG_PFBMP91-ES-BATT.html My company didn't have the printer, but had a hot-stamp marker. I think it was a Japanese made one, but I believe Brady might still make some as well. - Vasa

Hey rimbi, I had a similar project a while ago, I was trying to communicate PLC with a PC via serial and the guys here helped me out a lot. You can take a look at the thread below, it might give you some ideas. http://forums.mrplc.com/index.php?showtopic=24746&st=0 - VaSA

You are probably trying to input an invalid input/output number. FX PLC inputs/outputs are numbered in Octal... so you only have X0 - X7. X10 - X17. If you try to enter X08, X09, X18, X19 - it's going to give you an error.

What Steven suggested will probably work, but the "something obvious" that you're missing is this: --||--------|/|-------|/|----- X1 X2 X3 --||--------||-------|/|----- X1 X2 X3 --||--------||-------||----- X1 X2 X3

Are you saying that you've downloaded the program from Q02HCPU PLC and want to upload it to FX3U PLC? You cannot do that, the program needs to be converted for that specific PLC type.

Hey guys, Was wondering if you guys could help me out with one dilemma. I need to interface a Mitsubishi PLC (Q-series) with a Desktop Computer. The PLC is running a machine, which produces parts. Once the machine produces say 50 parts, the PLC needs to give a signal to the Computer (through a serial connection), and then the Computer would Print a specific label. First of all, I’m wondering if such interfacing is even possible with Mitsubishi PLCs and if it is, how can it be achieved. Does Mitsubishi have software for such task? Thank you. Note: I can get my hands on GT Works 2 if I need to accomplish this task but I usually use GxDeveloper. The Q-Series CPU is the basic one with 1 USB and 1 Rx-232, no Ethernet connections. All expansion slots on the PLC rack might be occupied already (not 100% on this).

Hey kaare_t, We got the first printer running, so everything should be OK from now on, just gotta do two more. So anyway, just wanted to thank you, since I wouldn't have done this without your help. Also want to thank everybody else who gave me advice. Thanks! - VaSA
-
Hey kaare_t, Thanks for the reply, I know why its outputting the NUL, but I cannot figure out how avoid that. I want to keep my output as a string, but you mention a small sequence program that inserts the control data. Could you please give a bit more details on how to achieve that? Thanks. - VaSA
-
Hey guys, One more question - if I want to add Header (STX) before my string output and Terminator (ETX) after my string output, how do I do it? I tried simply doing a MOV H02 to the beginning of my outut, but it outputs <STX>NULL, and same thing at the end, it outputs <ETX> NULL. How do I avoid outputting those NULLs? Is there a way to make PLC (Q-series) output STX and ETX automatically? Thanks. - VaSA
-
Yeah, I've already done that... seems to be transmitting what I want. So far so good... :)

Here's a snapshot of what Analyzer is showing:

Hey kaare_t, Good news! I went to RadioShack, and bought a male and female connectors and made my own cable the way you described above (cross with some of the pins shorted). I connected it, and BAM the SD light blinks and I get some data received in the 232 Analyzer. Now I just gotta figure out how to send exactly what I want to send. But this had raised my morale quite a bit! :o).
-
Alright, I've attached the PLC file. The C24 part is all the way at the end. Thanks. - VaSA FILTER PRESS MACHINE REV 3.rar

Yeah, I'll post it tomorrow since I don't have a copy at home. Ordered a spare serial cable so I can cut it open and short some of those control lines. Thanks for your help so far kaare_t, is this also how you learned this stuff? I thought it would be a lot easier haha. - VaSA
-
Also getting weird stuff like this...
-
Hey kaare_t, So I tried sending data TO the C24 module, and the RD light blinks, so cable should be OK. However, when I try outputting stuff, there is still nothing. Clicking on the RTS and DTR opens the serial port, correct? Also forgot to mention, for my Channel 1 on the C24 the Neu light (neutral i'm assuming) is OFF, could this effect anything? THanks. - Vasa

Hey Veganic, Thanks for joining in, all suggestions are helpful. - VaSA

I used the GX Configurator that comes with GX Developer as add-on, also I got some free software called "Free Serial Port Monitor". Any software you could recommend? Thanks.
-
Hey, thanks for quick reply. No the SD light never lights up.
-
Hey kaarte, Is this the cable pinout you're talking about? So I see, by shorting those pins, one fools the link into thinking that hardware handshake has been accepted. Is that the idea here? Thanks.
