  1. Hi, totally new to PLC's .. Just trying to do a university assignment I've connected a DTC1000 to Fatek PLC Port 2 - RS485 I want to know in which register I can find the measured temperature. A friend said you should add 400000 to the converted from hex to dec number which is mentioned in DTC manual. http://www.deltronic.su/userdata/files/dtc_manual_eng.pdf But I'm not sure which value should be used in manual and is 400000 the number to add (and where it has come from!) If I can just find the register, I can do the rest (just a bunch of normally open and close and  .. Thanks
  2. WRITE MULTIPLE REGISTER MODBUS

    Hallo my name is Danu, i have a CP1E wirh CP1W-CIF11 and connect to modbus RTU device, i have done with write single coil, write single register,  read single register and read multiple register. But i try to write multiple register,  the indicator of CP1W-CIF11 is off and if i check d memory its no data. I attached my cx programmer. Can you help me create write multiple register in cx programmer?  Thank you AD4402-modbus edit edit edit edit edit.cxp
  3. Please assist me with the following; regarding the ME96SSHA-MB Power meter data transition with Melsec-Q series PLC; We acquire to read various values on dedicated Modbus storage address registers at the simultaneous into a Melsec-Q series PLC via Modbus (TCP or RTU)  for calculation purposes. Naturally, since the reading of these variables are to provide accurate instantaneous results, it is a requirement that these values are to be read at one scan.   However, as can be seen below, there is a gap in address register range – of which, if all of these are scanned simultaneously, yields an exception error when read. This error is only avoided by scanning these data sets separately – which is not ideal for our application – since accuracy in calculations is imperative.

  5. Link register in Q series plc

    How to use link register(w) in ladder program? And how can we configure that ? And How to read and write values to that register?
  6. Compare not working

    We have this logic (on a CP1E) the desired outcome is as follows: When a bad part is detected, force the operator to index the machine 6 times, using a holding register to prevent a power cycle from resetting the count. once 6 cycles are recorded output that the bad parts are removed AND reset the count to zero.   What has actually happened so far: the count has gone to 6 and not reset. I have used CX Programmer to set the H0 value to zero but the compare still says it's equal (to 6)   I have read everything i can get my hands on regarding holding registers and compare functions and i can't see what is wrong. I have no formal training on this so i'm sure it's something simple. can anyone point me in the right direction?   Thanks guys    
  7. bit shift register

    Hello everyone. I m new on site. I need to an example program (done and running properly) that bit shift register. I will design a bottle filling machine. I dont know how to use these logics.  hardware dosent matter.   thanks for your interest
  8. I have Omron CP1H PLC and using Ethernet Option board to communicate through Ethernet. When I connect PLC to 2 Computer it starts malfunctioning and values in register get fluctuate. while I connect single HMI it works fine. Kindly give solution if anyone know. 
  9. Hi everybody. I'm just getting started with GX Works 3 and I feel a bit lost. If I have an external help file for my function blocks, how do I register this in the program? I can't find it anywhere when I double-click the fb library or in the e-manual Viewer. The file format is .CHM and I have imported this to GXW2 earlier.   /Niklas
  10. Hai i want to know how to save and retain the values of the program even in Emergency power off the PLC and on again? can any one help me?
  11. Hello All! I am having difficulties mapping register values. In the TURCK register there are 24 unique register bytes corresponding to different value registers (8bit x 24). These 24(8bit) bytes were mapped into RSLOGIX 5000 as 12(16bit) INT words ....INT[12] .. This means there are 2 bytes (2 unique register values) inside each INT word. WHAT I NEED TO ACHIEVE: 1. (BLUE outline in drawing) Write/Map a value of "32" into byte 7 of the TURCK register so effectively starting at  INT[5].8 in RSLOGIX           Drawing1-Model.pdf This will enable the value of CNT1 (encoder count) to be registered in bytes 8-11... 2.  (PINK outline in drawing) READ/MAP the values registered in bytes8,9,10 and 11(4x8bits) into a SINGLE 32bit INT value which will tell me the CNT1 value of my encoder. I am having problems when ever I try to COP a value of 32 (no matter what kind of array it's sourced from) into INT[5].8 & I haven't tried to map/read the values of bytes 8-11 CAN SOMEONE PLEASE HELP EXPLAIN HOW TO ACHIEVE THIS?! Thanks for your input EVERYONE! :D Drawing1-Model.pdf
  12. E1151 New Display Register

    Hi all, I wonder if anyone can help me. I have 4 test rigs setup with E1151 HMIs and FX3U PLCs (with two ADCs and one DAC).  They are running pretty well, and the HMI changes block fine when using Jump to Block, but when I try to get the PLC to change the HMI's block using the New Display Reg it becomes very temperamental. For automatic testing I want the PLC to prompt the HMI to change block, so I set it up with a PLC register, then set the HMI to use this register for the New display reg.  When I turn the PLC and HMI on I can run through the test, and at the end it changes screen perfectly.  However if I run the test again the HMI appears to "forget" to change screen.  I have checked the new display register and It lists the correct screen, but the HMI doesn't change. So far I have tried adding "SCRR" too the command list to use short recipe names (saw this on a previous post), and tried reducing the amount to data transfer between the HMI and PLC to see if it was a latency issue, but neither have worked. Has anyone else witnessed problems like this?
  13. IR register operation

    Hello, Can I add an offset value to IR register? for example, MOVR D0, IR0 and I have an offset value stored in D1, for example, &100, could I add the offset of D1 into IR0, to get IR0 pointing to D100? I know I can just do MOVR D100, IR0, but for purpose of versatility, I want an offset to be added in such a way. Thanks in advance. Xing
