  1. Hi all, I need to keep my count after power-up. I tried tech note #63317 ( http://rockwellautomation.custhelp.com/app/answers/detail/a_id/63317/related/1 ), not working in my plc. I tried again but this time I put enable bit to zero as tech note 21205 asking for ( http://rockwellautomation.custhelp.com/app/answers/detail/a_id/21205/kw/21205 ), again, is not working. PLC is compactlogix 1769-L32E firmware 19, ( PLC, HSC, HSC, Power supply, Input, Output, end cap) 1769-HSC take more time than plc for boot. So OK and run LED on plc turn solid green before 1769-HSC OK LED is solid green. This means first scan of plc want to set current count while HSC is not ready. AB Tech note use first scan, I call support and they don't have any issue with this logic. Maybe they switch plc mode from program to run, by doing this they got first scan with HSC OK LED solid green. Another option is to use GSV insctruction to get HSC module state. I found logic for contrologix ( http://rockwellautomation.custhelp.com/app/answers/detail/a_id/57569/related/1 ) but nothing for compactlogix. Once GSV instruction tell me module is OK, I will write current count value. I left 2 screen shot, before and after power up. My current is alway 0 after power-up, really need your help now. Can someone can test tech note 63317 with a real power-up? thanks

  2. I got similar problem few time in the past. When I did RSLogix500 installation with a Office program open (Outlook, Word, Excel) installation start each time I start RSLogix. Maybe this issue is not in version 8.30. Be sure all progam is close when install Rockwell software.

  3. If you want to use virtual machine, I strongly suggest VMWare. I tried Sun VirtualBox and use of SerialPort with this software is a real pain in the booty! VMWare is more powerfull and easy to use with different comms port, Ethernet, 1747-UIC DH-485 network adapter, ect... VirtualBox also have few problem with USB connection, just goolge VirtualBox usb problem, you'll see.

  4. I did few project with modbus comms. Ken your right, paramter can be read/write by using parameter number. Sometime you'll need to add 1 to modbus adress so 8449 error code will be 8450. If you didn't take care of this offset, logic status data 8448 will be read as error code 8449 (8448 + 1). Don't write parameter on all plc scan, EEprom failure will occur. Another thing, for read more than 1 parameter, I change the size in Element value (see picture).

  5. Has this been working and now its not? Never work. It can run 1 month without any fault and I can get 3 fault in the same week. Can you post the DriveCliq topology? see attachement From the D445 to the CU's- is this profibus or profinet? Profinet Can you just post the alarms and not the history- a little easier to see (I think) When I went online, alarm was not present. Someone cycle the power of the machine. --------------------------------

  6. Hi all, I got trouble on my Drive-Cliq network. I lost Drive-Cliq comm for no reason. I replace wiring and wire is not close to power and motor line (not EMI). We have 16 drive divide in 4 group: 2 Simotion D445 control 4 drive 2 CU320 control 8 drives I check online % of utilisation of CU320 and it's close to 55%. I only lose comm on drive connected to CU320, I attach a screen shot. Also I got alarm 30041 many time while running. I check 24Vdc supply voltage with a good DMM (min latch 1 msec), I change power supply for that drive and still got this alarm. Any idea?

  7. Hi all, I got a strange problem. I have a project with 1 M1100 who communicate with 1 PV+ thru ethernet and 7 PF4 drive thru modbus DSI by using 1763-NC01 adapter. Don't worry, I do cascading comms, so DN or ER bit of previous msg is used as trigger for next msg (see picture). Everything work perfect unitl I start the drive, then I got timout error #37 on almost all drive. There is no difference in amount of data and logic in comm while the drive is stopped or running. I'm looking ER bit of MSG instruction, while all drive are stopped no ER bit are set and while drive running all ER are set. I found nothing in AB knowlegdebase on this kind of issue. Last point, I did similar project at least 7 times and I never got this trouble with the same comm logic in M1100. All previous project use the same drive but with an older firmware (5.10) and this project use firmware 6.01. New feature of firmware 6.01 have parameter 118, regarding comms Save / Ram (parameter is set to Save but I didn't write any paramter in logic). thanks for your help

  8. I have a very old CRT touch screen Dynapro model 1021. I want to replace this screen with a standard pc. Model 1021 is a kind of intelligent monitor who receive ascii string and build graphic interface, push button, text, ect. Only 1 RS-232 port is used for video and touchscreen. I attach "how it works" pdf. dynapro sell equivalent monitor in 1995 called ErgoTouch 3170 TCS I'm looking for driver or C++ librairie or any info about this kind of screen. thanks for your help Application_developer_guide.pdf installation_manual.pdf

  9. I tried many USB to serial and never got good result. I used PCMCIA card from Quatech ( www.quatech.com ) and it's working as a native serial port exept for PIC module. Now I use Express Card from quatech again and like PCMCIA, it's working like a native serial port. PIC module doesn't work with PCMCIA and ExpressCard but 1747-UIC can replace that old big box most part of the time (when baud rate is 9600, 1747-UIC doesn't work PIC module must be used).

  10. I want to use Cx-One in VirtualBox vm. Cx-Programmer work, but I have some problem with Cx-Designer. I can upload but I can't download. When I try to download, the hmi go to Upload/Download screen, then after couple second hmi goto transfert screen and after long time I got time-out. Any idea??? HMI: NS5-TQ00B-v2 system version 6.26 Project data version 6.00 Cx-Designer: version 3.111 Download/upload with serial.

  11. I think Profibus is a good way. USS is slow, used for program the drive with drive software. You'll need to add profibus adapter on the drive. see att. for profibus documentation. wish I help... gsg_mm4_profibus.pdf MM4_PB_OPI_en_0202_I.pdf

  12. Sorry ROn for the delay, verry bussy this time. Speed is around 2 mm per msec. This means scan time of 3msec, lost 6mm (+/- 3mm). I do a periodic task (2 msec) so I still got error but logic is more stable, not flucation du to scan time. When logic was in periodic task, scan varies from 2 to 5 msec! Really Compactlogix miss input interrupt.

  13. Hi all, here is my issue: I use a compactlogic (1769-L32E v17), photoeye (1769-IQ32T), and encoder (1769-HSC quad encoder X4) for mesuring book on production line. Logic is easy, on rising edge I wrote current count value in a DINT, do the same for falling edge and then I substract Falling edge - rising edge and multiple by belt ratio. Formula is: (FallingEdge - RisingEdge) * BeltRatio [i do little more detect encoder count rollover] Logic work but varies a lot. I have +/- 10 mm on 290mm book to much for quality control. I think myt scan time affect my reading and I search how fix it. 1- I decrease input filter on 1769-IQ32T to 1 msec 2- I decrease RPI for virtual backplane to 2msec 3- I decrease system Overhead time slice to 10% in Controller properties -> Advenced tab 4- My scan is around 3 msec, some time more for short period. I look for instruction like IIM in SLC serie, this instruction doesn't exist for compact logix (only IOT for output). Knowledge base answer id 28816 - MicroLogix 1500 Controller(s) can scan the onboard I/O faster than any 1769 expasion I/O.. http ://rockwellautomation.custhelp.com/app...ail/a_id/28816 My last solution is to create a periodic task (2msec) for monitor this input and do rising / falling current count write. but all logic scan will be increase a lot... Looking for good idea, thanks
