Can you upload the QJ71MES96US manual?  

Hi Paolo. Cant say ive ever used this device before; however the link para error can sometimes conflict with your 'points' and 'X/Y assignment'. To avoid complications; I would try and run your rack with the bare amount of modules possible- to ascertain what is causing your issue. For example; Can you boot just the first CPU on its own? Then add the extra CPU, once you got this running then add the intelligent module afterwards. Another thing to try- is formatting PLC Memory; when playing with the IO and CPU Parameters; sometimes these do not 'clear' fully.  Q-Series expects the primary CPU in the first slot; other CPUs can normally be placed anywhere else in the rack. Regards Daniel.  

This rings 'a bell', it might be worth checking the tech notes, what firmware revision are you using?

I would just create a 'Startup' tag with a timed delay; then call all your sub routines with it.

If you are doing this in GXWorks 2/3 then yes that is fine. Technically speaking; you are 'upgrading' your CPU so this should create no problems when changing the Model Number.  If you are changing TO the Q02(H)CPU- then yes you may encounter issues as the device ranges and other such things will be smaller, so some changes to your program may be required. If you encounter any issues feel free to come back to us. Regards   Daniel

Sounds like you need to write some sort of script or internal logic in the GOT. The alternative would be to do all this in the PLC.

I hage just checked my version of GX Developer which I believe is the final release (8.20W) and there are no options for your CPU. I have also checked GX IEC Developer Versions 7.01 and 7.04 and your CPU is not available. However GX Works2 version 1.535H DOES list your CPU, hope this helps.  The equivalent CPU you would need to purchase is the Q06H and an ethernet module (QJ71E71100).   Regards   Daniel.

Hi soundararajan Normally for software updates you have to log in on the MEAU website and assuming you have valid licences etc- you should be able to get access to the latest software updates.   Regards   Daniel.

Hi hq27676996 Firstly welcome to the forum. Have you checked for Add-On Profiles on RA Website? I had a similar problem with a 3rd party product and managed to solve this wayz   Regards Daniel

Hi Thacks. Firstly welcome to the forum. Unfortunately I dont have any experience with your product, however when configuring EDS Modules- sometimes Rockwell release new Add On Profiles that need to be installed in order to get you certain functionality. Bit of a long shot- but might be worth looking on the RA site to see if such updates exist.

Looks good, from what I read...you can test this with standard Mitsubishi Function Blocks for fixed buffer communications. Sounds like a nice little project.

Looking through the documentation now; it would appear to be very simple to set up on an Allen Bradley system. In terms of your options for a Profibus DP Slave --> ProfiNET IO...theres are loads of them out there which would be suitable.  Which option would be feesable for you? 

Hello Ninza T. Firstly welcome to the forum. 1. Unfortunatley the Standard Q Series does not directly support Ethernet/IP Protocol. There is a CPU 'Q12DCCPU -V' that apparently supports both protocols, however it is very expensive. 2. As above; ProfiNET is not supported on Standard Q Series, the onboard Ethernet Port on the CPU is designed for basic PLC --> PC communication and you shouldnt expect to be qble to send/ recieve any large anounts of process data. 3. Socket Communications is supported- but again not on Ethernet/IP. 4. For this point, you will need to consult your products manual. If there is compatibility; you may need to purchase a QJ71E71100 module. You however have a number of other solutions; i. Use the new iQR platform that directly supports ProfiNET. ii. Stick with the Q Platform- Use a profibus master module (QJ71PB92D/V) in conjunction with a gateway such as Prosoft or Anybus. This will allow you to interface to your hardware on a ProfiNET network. iii. If you have access to a CompactLogix or ControlLogix- these will perform this task with a simple Ethernet/IP Connection. If you have the camera and PLC to hand- it may be worth investigating the direct compatibility first to avoid any unecessary money and investment. Hope this Helps Regards Daniel

Once you have made the configuration change you could configure 2 Time on Delays. With your start button- start the first timer, on the completion flag (timername.Q) start your 2nd timer. On completion of timer2 (timername.Q) restart timer1. timer1 running runs motor 1 timer2 running runs motor 2 stop button should clear any set bits down to zero and have the sequence back to the start. The timer value can be displayed on the HMI using your 'timername.ACC' The above assumes your using an IEC compliant language. If your in old school mitsubishi land...you just need to examine the 'T#' number.  Once you have this working- you can then start considering interrupts (such as Emergency Stop) obviously the motor will stop- but perhaps you will want the count to remain and continue when the start button is pressed.

Hi Walks. Does your weighing scale support Ethernet/IP? Normally with a 3rd part products- it is set up as a 'GENERIC ETHERNET MODULE' (or via an EDS sheet) and the data structure size set. Then you would create a custom UDT or if the Manufacturer has supplied one; simply import and create the instance.  I have worked with KEYENCE Products in this way and generally have worked very well.

Hi Bruce. Have you confirmed you have an active Profibus connection with the node in the HW Config? If so...check you have allocated the correction I/O configurations (if this is freely selectable, make sure you have the right amount of bytes for input and output).  What about the inverter parameters and configuration, has this been fully configured? 

Hi Tranthanyung. Unfortunatley there is no file attached?. If you upload, im sure someone will be happy to help you.

Hi Leonidas. Firstly welcome to the forum.  Im not 100% sure on GX Developer; but certainly IEC Developer and GXWorks 2/3 there is a PLC Parameter to enable timing over a certain threshold.  The other option is to roll on another timer...then clear them down when finished. So you want to count 36000 in a counter?

So you want to collect the average?, or?.. Why not use a 100ms pulse to catch 10 datas then divide the sum by 10?  So then the average updates every second...

Hi Nanasakiai. This might not help you much- but I have checked the software design for a fast counting card my company used on ET200S Profinet. I/Q Addresses start at 10.0 for 6 Bytes. Q14.0 is set (this is the request for the software gate to open). And we check I15.0 (this tells us the count is valid and the gate has opened). And the Actual Count is read out of a Double Word (ID10).  Apart from that- there isnt really any other code. This station has the ability to simulate conveyor increments but this is done cyclically in the logic and doesnt rely on any hardware to do this.   Regards Daniel.  

There are some very good examples on the Siemens Automation forums- and some freely usable SCL Source Code that you can import, modify to your requirements and compile the block(s).

Hello and Welcome to the forum. Have you checked the program to see how many parts are actually being stored/ monitored? You may find there is a buffer somewhere in the PLC that is keeping previous values. Otherwise yes you could combine a REAL Array...and load them into something like a FIFO, im not familiar with the 1500 series FB's but there will most likely be a standard Siemens block you could utilize for this. The ARRAY would depend on the number of values you wish to save, for example 10 points would be declared ARRAY [0..9] of REAL.   Regards   Daniel

Hi Arnie. Please send me a picture of your PLC including all attached modules. I will send you a GX Developer project that I can bench test on my CPU and confirm working Otherwise send me your project in a .zip and I will locate the problem.   Regards Daniel.

Hi Arnie. You are trying to write to the memory card, is this correct? Normally with a CPU of this type- we would write to the Standard ROM. The 'check' button simply checks that the data you've input into the IO Assignment is acceptable (for example 16 points for an intelligent module would not be accepted). Try the 'Read PLC Data' button then save and try to download again.

Okay- can you access via RSLinx? Perhaps the firmware has become corrupted, can you download via ControlFLASH?
