  1. NB-designer software

    Dear all, It is the first time I use NB-designer to create a HMI programme for NB5Q, and I meet a problem about the bitmap and vector graphic library. Infact, my project requires some icons which do not include in bg&vg lybrary. I try using "add new bitmap" funtion but its result is just a "non-graphic" space. Could anyone tell what I did wrong? And how to make it? Thank you! Best regards!
  2. Hi all! I'm a very new member of our forum (and in automation area too). I'm trying to use PLC CP1L (M CPU type) to control a inverter model 3G3JX. You know, the easiest way is using build in function ModbusRTU Easy Master, but I still can't make it work. Let me talk to you how I use this build in function so that you can help me out. I want to give a run command to inverter that its address is set to 01, so I inset these follow values to fixed DM: D32300 : #0001 D32301 : #0005 D32302 : #0004 D32303 : #0000 D32304 : #FF00 Then I kick up A640.00 ON using "SET" code. Before that I wrote a frequency value #500 into the "Frequency Referency Register" which its address is #0002h. D32300 : #0001 D32301 : #0006 D32302 : #0004 D32303 : #0001 D32304 : #0500 But there's nothing happened, and in the DM address D32502, I just saw #0080. I don't know why, everything is just ok but it didn't work. I show you the value of parameters that I set to inverter: A001 : 3 A002 : 3 B089 : 1 C070 : 3 C071 : 5 C072 : 1 C074 : 1 C075 : 1 C076 : 2 C077 : 0 C078 : 0 and somes... Would you please tell me why it didn't work? Thank you all!
  3. Dear all! I want to control 3 D700 inverters by using "computer link operation protocol" function in PLC FX3U but it still doesn't work. *-*In D700, I set : Pr 79 : 0 Pr 549: 0 Pr340: 10 Pr 117: 1 Pr 118: 192 Pr 119: 10 Pr 120: 2 Pr 124: 0 *-* In FX3U: I choose CH1 check box "operation communication setting" Protocol : "non protocol procedural" Data length: "7bit" Parity: Even Stop bit : 1bit Transmission speed: 19200 pbs H/W type: RS-485 Transmission control procedural: Form1 (without CR,LF) --------------------------------- PLC programme: LD M142 OUT M151 LD M143 OUT M161 ; RUN/STOP COMMAND LD<> K2M150 D40 OR<> K2M160 D41 OUT M77 LD M77 MPS AND<> K2M150 D40 IVDR K1 H0FB H0 K1 IVDR K1 H0ED D900 K1 IVDR K1 H0FA K2M150 K1 AND M8029 MOV K2M150 D40 MRD AND<> K2M160 D41 IVDR K2 H0FB H0 K1 IVDR K2 H0ED D901 K1 IVDR K2 H0FA K2M150 K1 AND M8029 MOV K2M160 D41 ------------------------------ D900: INVERTER 1 FREQUENCY D901: INVERTER 2 FREQUENCY ----------------------------- I don't know where I'm wrong ... the error code is 1 (means no respond from inverter) Please help me!
  4. Dear all! I'm in trouble with ABB's inverter model ACS550-U1. I have read its user manual but still can't find which exactly frequency referency register. This's the first time I user an ABB's inverter so in a short time I can't do what I do with OMRON's inverter. If I use 3G3JX, to send a run command from PLC, I write the frequency value (resolution 0.1Hz) into register 0002 (freq referency reg) first, then I turn on coil 0001. Is it the same if I use ACS550-U1. In case it's the same, Please tell me which corresponding register. Thanks and best regard!
  5. Dear all, I have used PID instruction in my program, but it always result zero value and I have no idea what is going on. Is anyone have experience like this before and tell me where I'm wrong!? I attached an emage below hope you can help me figure it out. Thank you!
  6. PID instruction in CJ1M trouble

    Thank you, It's true that I did used one DM in C+7 to C+38 acidently. I fixed it and it's ok know
  7. PID Instruction in Functio block area

    Thank pfort, your information is very useful.
  8. Dear Automation Guy ^_^ I've been starting written a CJ1-PLC's program, because it's a very big complex program, I want to put all the repeat tasks into function blocks in order to make the program easy to read and debug. In one function block that uses PID instruction, I found that the result word was always zero, as shown in the pic that attached below. In this function block I defined some variable as below: 1. PID_CW : internal variable, data type is WORD, Array size is 39 PID_CW[0] = Setpoint PID_CW[1] = Proportional Band = 5% PID_CW[2] = Intergral parameter = 20 PID_CW[3] = Derivative parameter = 40 PID_CW[4] = Sampling period = 20 PID_CW[5] = #2 (0000 0000 0000 0010) = reverse control, enable changing PID parameter each sampling period PID_CW[6] = #0505 = number input/output data bit is 13, 0-1FFF Hex (0-8191 Dec) range. 2. Var3 : internal variable, data type is UINT (content PV value) 3. Var4 : internal variable, data type is UINT (Result word of PID Instruction) Setpoint and PV is converted to 0-8191 Dec Range before execute PID Instruction. I can find where it's wrong. Hope you can give the anwser why does the result of PID instruction in this case is always zero? Thank you! With kind Regards!
  9. PID Instruction in Functio block area

    Oh really!? That's it! Thank you :) I have just read in PID Instruction help that PID is not alowed in function block area, I wonder what it means? Have you ever use PID in a function block successfully? It's very tired to start writting code over again :(
  10. [Help] Analog signal error?

    I think the error may possibly be "level lost" because it occurs when the tank is empty (the machine turns from on to off then the liquid is pumped out from the tank to another tank for safety). But I still wonder why this error does not auto-reset when the liquid level in this tank rises up again, and I must reconnect the 24VDC power supply to it again to push it work (this's like reseting the sensor)
  11. [Help] Analog signal error?

    Dear all, I use a level measurement device [AKS4100 - Danfoss] and a motor-ride valve [iCM 20 - Danfoss] to control the liquid level in a tank. The 4-20mA analog signal output is set to AKS4100 in order to feed-back the current liquid level to CP1W-ADxxx, the analog input extension unit. Everything was ok till an error occured after 5 days from the first time system started. The PLC often receives the 3.6mA feed-back signal from AKS4100 (the correspondence DM memory of this analog input signal has a value of -160, prescaled, it is 3.6mA). I thought the liquid level was just at 0%, so I checked the real level in the tank, but the level was about 40-50%. I'm very confused in this situation. Can you tell me why this error takes place and what I should do to fix this error? PS: I've read the AKS4100 user's guide and I found that it does mention "error output set to 3.6mA" in technical data "current output load", but I can't understand what it means. I attach this document in case needed. Thank you very much!
  12. [Help] Analog signal error?

    Unfortunately, this sensor is completely covered by foam, polyurethan, in order to keep it working in a very harsh environment; low temperature ice frezzing environment when the machine works and high humidity, wet environment when the machine stops. So, I'm unable to see what the error codes on the transmitter display. Thanks Geir, I'll try to find out what happens to this sensor.

    Thank IO_Rack! I'll try it
  14. NB-designer software

    Dear Michael Walsh, There's another problem about bitmap image that I meet after success in adding a new bitmap graphic. That is the image could not keep its shape when it is applied in small size. First, I creat an image by drawing it by CAD. Then, using "export" function in CAD, a picture is generated in bmp format. Second, I use Corel Paint software to crop the necessary area. And the last, this final picture is added to bitmap graphic library of my NB project, follow your guide above. But when I resize it on screen to about size of W20xH30 and download the screen to NB HMI, it loses its shape. Some lines and area are missing. Would you please tell me how to solve this problem or how to create a bitmap graphic correctly? Thank you!

    Thank Michael Walsh! It's very helpful.
  16. thank you! One more question: Does it work corectly in icing invironment? I used a omron's promixity sensor (E2E) that could operate in temperature range about -40 to 80 Celcius but It fail when temperature reached -35 Celcius. I found that cause of the frozen fog in evaporator room.
  17. Dear: all! I'm looking for a promixity sensor or a limit switch that can operate normaly in -40 Celcius and icing enviroment. Omron's promixity sensors (E2E-X3D2-N) have been used but didn't work. They were broken when the temperature reached lower than -40 Celcius. Would anyone suggest me what sensor/switch should be used is this case? Many thanks! With kind Regards!
  18. Hi everyone! I want to connect PC to Mitsu's PLC QCPU via the ethernet port on Ethernet Module QJ71E17 using Standard Cable 10BaseT. In fact I want to go-online to the PLC via ethernet port by MELSOFT GX-Deverloper. I successfuly did it when used a computer with XP OS but it's not when used a computer with Window7 OS. Even thought I did the same things to 2 computers but the results were different. I don't know why? I set PLC ethernet port's IP to 192.168.10.2. On XP OS computer, by enter "internet protocol (TCP/IP)", the IP was set to 192.168.10.1. On Window7 PC, by enter "internet potocol version 4 (TCP/IPv4), the IP was set to 192.168.10.1 (the same as XP Computer). When plugged-in the cable: - The conection icon on the bottom right was normal - There's a warning symbol (yellow tri-angle with exclamation mark on central) appreared on the connection icon I've tried hard but it didn't work out, please help me Thank you very much!
  19. Thanks kaare I've not pinged it yet, I'll try it. I had changed something in "device manager" before. I changed some parameters in "port setting" of com port 3 of my computer, when it's in use in other app. Does it relate to this?
  20. Dear: all! First I just want to say that I'm a newbie in automation area, so I have lots of communication problems. My recent project requires something that I can manage it. There's a PLC CP1H controls 2 inverter, connects to a HMI and communicates to 6 others PLC CP1H as well. I user 1 option board CIF11 to control these inverters (cause I just can only use Modbus RTU-Easy function, I dont know how to use CX-protocol, and how to write CRC-16 calculating code). To communicate to HMI and others PLC I use serial board SCU31 (1 RS343 and 1 RS422/485 port). The problem is how can I make these PLCs communicate to each other? This is the first time I use SCU31 so I'm so confuse. I want to use CX-protocol to make it work but I dont know where I begin. Can you give me some documents (kind of user guide) or solution about this? Thanks for reading!
  21. Dear all! I have a question that "does Modbus Easy Master Function work only when Communication option board CIF11 or CIF01 is eqipped?" Cause I have been using Communication Extended module CJ1W SCU31 and I can't use Modbus Easy function to communicate to Inverters. Is there any way to make it work with CJ1W SCU31? Thanks!
  22. FX3U and D700 inveter communication !?

    Ok I have just find out what's wrong Thanks for reading ^_^
  23. FX3U and D700 inveter communication !?

    I have read FX communication manual and did exactly what it say. The problem is there's no respond signal from inverter and I don't know why >"<
  24. GOT 1030 connect to PLC FX3G!

    Dear all! I often use HMI and PLC OMRON but my recent project requires MITSUBISHI devices. It's a quite strange to me to start. When I create GOT's screens using GT Works 2, I have some questions. Assume I want to display a number, such as 10,01, and "Numerical Display"'s device is D500, so: 1- What is the numeral value format in D500 (BIN, HEX, DEC or BCD)? 2- How to display the decimal point (just mov 1001 into D500)? 3- And in GOT 1030, what "Numerical Display" Object's format that I have to chose (Signed decimal, Unsigned decimal, Hexadecimal, Octal, or Real)? 4- Conversely, the same questions for "Numerical Input" Object. Assume that I have to enter a 10,01 (decimal) into a "Numerical Input, so how can I do it? I don't have GOT1030 and FX3G right now to test cause it will be delieved at least next 2 week, but it will be late if I wait till have them. So please help me >"< Many thanks for reading.
  25. 3G3JX communication to ACS550 (ABB's inverter)
