Hi ! In manual for 3G3MV-PDRT2 I found only it is powered from Inverter. Does it mean that it does not need any current from devicenet network. I am counting current consumption in my application and I do not know if I should count sth for these cards or not? thanks Pawel

Hi ! I have program in PLC - when 1205.08 goes ON the screen 18 should be displayed with string number 8. I do it as below: The problem is that real NT21 does not show the string No.8 - WHY? f.e. when I set string from the table no. 0 to 7 everything works - I see those strings, but strings 8,9,10 - they are not shown. What is going on? Pawel

Hi ! To set color word lamp I use W107 - just 3 lowest bits (6 different states). CX designer can have max 10 states - it means I can use max 4 lower bits. What abouts bits 4 to 15. Can I use it for different demands or I have to reserve it for the word lamp. Right now I cannot, but maybe I can set somewhere upper limit for word lamp f.e just 3 lower bits. thanks Pawel

Hi ! I've just noticed that in my NSJ in Global Symbols tab I do not have D area like D100, D101 ... When I change the PLC to f.e CP1H I have D area addresses in global symbol. Is it normal in NSJ and where I can find D area address? thanks Pawel

I got it - I had to change Pin Out of DB9 and I have perfect communication with scale. Topic can be closed

Hi I have scale which have DB9 female plug. I used CX-simulator to communicate with virtual PLC and it worked. Now I decided to attach this scale to RS232 Board to CP1H; it has female socket so I had to exchange female plug to male plug in my scale. I used the same pin out and I have framing error - just look my PLC settings and flag A528.03 : What is the problem? - maybe I should exchange wires in my pin out 2(txd) and 3(rxd). Rest of wires are the same as I look at scale pin out wiring? Thanks Pawel

Hi ! Everything worked until yesterday. Terminal shows message "Systemfel Corrupt Block 250" When I made PLC diagnostic I got error 6706 in step 879. I did something and now there is "No Errors" but "Corrupt block 250" on terminal still in force I am not really familar wth GX Developer, but I think that something is wrong with CPU. As you see: I have monitor mode and I try to Force On M562 to check if instruction DDIV works ( value in D472 should be changed - D472 is only in this step), but nothing is happening when I try to force the Input On Value in D472 is also really strange. Maybe you could give me any clue to find out what is going on with this PLC and what the E-terminal message can mean. Thanks Pawel

Ok - I will do that this way and what about overwrite D472 value. I cannot do that using Device test - even I write f.e. 4 DEC to D472 in Device test still I have negative value in line 879. At this moment Line is not active - DDIV instruction is not executed. thanks Pawel P.S. I didnot know that GX-Developer and/or Melsec is not functional and user friendly

Wow - what's a pity So - How I can switch on step 879 (from the GX Developer) to check how the instruction DDIV works - I mean what value will be in D472 after it. How I can set different value in D472 - This minus is strange for me. This values goes to timer and if it is negative it can give error. When I look into Device Memory a lot of D addresses have negative values - hmm Pawel

In Omron FORCE ON works with the highest priority. IF you want to Force On the internal input you can do that whenever you want - doesnot matter if the PLC program turn on/off this input. Melsec does not work this way? I tried also to change value D472 using also Device Test (word device) but nothing change with the value which is beneath D472 in ladder view ( see picture in first post) - is it normal? It is completely strange if I compare it to Cx-designer for Omron. hmm thanks Pawel

OK - I will find out what cable and soft I need to connect to E-Terminal. I use mostly Omron and force on works, but now with this FX1N it does not work. Why I cannot force on input M562 - maybe there is some other way. Pawel

Hello ! I read carefuly manual for LUFP9 gateway and it is mostly dedicated for inverter made by Telemecanique and one LUFP9 can be master for max 8 slaves. Modbus RTU can have 255 addresess - so 8 is not enough for me - probably I will have more slaves. I found that: 1782-JDM-2 : http://www.wrcakron.com/devicenet.html It looks good and the manual is more useful. I sent email to producer how I can purchase it in UE, but I have also tech question. I have some FB for PLC to send a modbus RTU command to slave. I have idea how to implement it if I use SCU card, but I am not sure how I should use this FB to send a command to Modbus RTU slave, which is connected to this gateway. Maybe you know some tip, any clue? thanks Pawel

Hi ! I will have many temperature sensors. I could use some as MODBUS RTU slaves - less cables, but I cannot find any DeviceNet module - Modbus RTU Master - is there any? It is worse idea, but I could also use Modbus RTU Master, which could be some device for CJ1M - the problem is length of cable - I would have to install two wires to another building - one for devicenet, one for Modbus RTU. In this case what device I need? Thanks Pawel

Hi With cable which has pin out as above you can also connect CX-Simulator with NT21 using NT-Link (1:N). I set up this configuration on CP1H simulation. For NT-LINK I had to set up Serial port 2 as below: Make sure you set the same values in port A of NT (38400 baud rate (no faster) and 0 Unit No) After you transferred settings to virtual PLC you have to disconnect and connect CX-simulator to refresh settings. It works much faster then hostlink Pawel

Hi ! I set 8 parameters in my Recipe table. but when I try to set "No Of parameters" to 8 in General Tab I get message: Does NTST supports only max 7 parameters or I do sth. wrong. Thanks Pawel

I got it In mean time I switched ON Resume Function in NT21 and finally I found in manual the answer: That's why when I downloaded the new memory table it wasnt refreshed. topic is closed

Do you see attached pictures - I use FF and I do not have it on the screen?? - What's a day!!

When I read some topics about modbus at the Omron forums there are same examples how to communicate with modbus slave/master through SCU card in CJ1M - you need to use CX-protocol to communicate. This gateway is a good idea, but I am not sure how I could control data in Modbus network by program in PLC through devicenet. I can have problem to get any support for it - it is Schneider product and I am not really familiar with it. Before I make a decision I have to be sure I will do it. Does anyone used such a device and can give any example, advise e.t.c ? thanks - all the time something new

You think that if I use DeviceNet module DRT1-232C2 and converter RS232 ->RS485 I will be able to implement Modbus RTU protocol to establish communication with MODBUS RTU slave devices (temperature sensors)? Thanks Pawel

I forgot to write - I use USB-serial converter (some cheap one - Prolific) with NTST 4.7 and WIN XP and it works perfect. Pawel

What cable did you use to connect PC with NT21? Standard cable to connect PLC and NT21 has 9-pin male connector from both side. PC comm port has also 9-pin male connector - it will not work - did you just exchange male to female connector with the same pin out or you changed something?

I have Windows XP - Media Center 2005 and I use NTST 4.7E - communication goes without any problem. I haven't used NTST 4.6 - I cannot say if it works or not. Pawel

Hi I read in NT21 manual about System Installer application. I have System Installer with my NTST 4.7 The question is how I can install the system in my NT21 ( I mean - how I can establish connection) - it should be possible, but when I look at help in System Installer application - there is nothing about NT21 - there are different PT's. Can I do it with NT21 or not? Thnks Pawel

Thanks PDL - once again I overlooked something It worked as it was written.

I found this NT21 like you, but when I clicked Go I cannot establish connection. At that time I started read help and there is info how to install it in some other NT not NT21. Do you have the same or you know how to download it? Pawel
