I am working on resolving issue in Press Machine where previous engineer has developed logic as per attached file. the atatched screen of HMI can only access by Engineer and only Engineer can set value of SPM (Stroke per minute). Once switch is set on the SPM of any job can not go beyond set value. The issue I am facing it when we power cycle, the switch get off and the register D2842 get SPM back to normal (set as per the die data) not by eng. How I can hold that data after Cycle power?

Hello to everyone. I hope you are doing well. I have a KINCO PLC HP043-20DT. I'm communicating through free-protocol instructions XMT and RCV. The manual states that memory registers SMB86, SMB186 and SMB286 contain information about the state of the reception instruction. I would like to ask if any of you know of the existence of an analog register but with respect to the transmission instruction, instead of the reception. The manual does not indicate it and I could not find any information online. I've sended an email to the manufacturer but, until now, I have not receive any answer. Otherwise, how could I search for this information? I tried through the manual providede by the manufacturer, but maybe there is other way. I would appreciate any information. Thank you so much. Kind regards.

i want to use indirect register, but why contact 100,IR0 is not ON, is it my program correct?

I'm writing a PLC program (Q Series Mitsubishi PLC, GXWORKS 2 Software) for a package sorting machine. The logic of the machine is the following: Packages are induced in the conveyor. A barcode reader scanner gets the package barcode. Barcode is send to our SMS (sorting management system), it calcules the exit and send it back to the PLC. Package travels to the calculed exit, then is derived into the chute. The tracking of the products is done by an encoder and a shift register. This means that every memory address represents a physical position in the conveyor. Then, the shift register move the bits representing the packages along the memory buffer, till the bit arrives to an address that represents an exit, so the package can be derived. My problem is not the tracking of the product, but the product ID tracking: When a package enters in the conveyor, an ID is set for that product (1,2,...,n). The idea is that this ID is used to track the state of that package, for example if the package was derived in the correct exit, if it has a damaged barcode, etc. My question is, how can I track this ID along in an efficient way. I was thinking in use the same shift register not moving a sole bit, but moving a larger number for example |1|0000011|, where the first bit acts like a flag that represents the existence of a product and the rest of the numbers is the product ID. When the flag gets to the exit address I can substract 10000011 - 10000000 = 00000011, to get the product ID. Is any more efficient way to do this ?

Hello, I have an M2I Top RW (model: 1000WD) connected to a Schneider Modicon M221 PLC. The HMI is connected and I is working perfectly reading data from the PLC via ethernet. I can't seem to find a way to write to the PLC from the HMI. I would like to control the PLC from the HMI, I know this is possible with Fatek PLCs with the same HMI model. please help - how would I create a bit command from the HMI to the PLC? what registers? what inputs in the PLC? thanks

Dear Engineerds, My Master (non siemens) doesn't see the Holding Registers of the Slave (S7-1200) plc. However the Q coils are fine and all Diagnostics don't show errors. The Hardware: S7-1200 – CPU 1215C CM PtP – CB1241 RS485 (6ES7 241-1CH30-1XB0) - Half Duplex RS584 Firmware: Modbus_Comm_Load (V3.1) Modbus_Slave (V4.0) I've tried with various DB, UDTs and manipulating HR_Start_offset parameter with no success. Could you advise what am I possibly missing? Modbus_Comm_Load_DB_Snapshot.xlsx Modbus_Slave_DB_Snapshot.xlsx

I have a 4PP015.0420 panel with the led error that stays between green and red, and it doesn't work.The sequence of the LEDs at power: Yellow Red Green Red Green Green Green Green&RedAnd on the display : Version 1.1 Status 400041000I think there is a Status Register that indicates the errors.How can I see it to know why the PLC is not put in RUN?Thank you in for your help.Sorry for my english

hi all, i'm currently trying to shift register some data in the floating point (double word) format, just for an example i,m using a 0-20mA 0-40 bar pressure sensor to gather information from a can filler and want to log the data for lets say the previous 20 cans. i understand how the shift register works and can get it to work with single word just fine, im using floating point to make my life a bit easier by using sleepy wombat's scaling function block, i need decimal points as i will be expecting reading around 4.5 or so bar and expected to be within .2 tolerence this will then have to displayed on a HMI, which i assume will be easy enough

Hello I'm new with GT Designer 3, I'm writing code for a GOT2107 HMI. I have a few buttons that when you press it, the LED on the switch comes on, and when depressing the switch the LED goes off. That's good, but how do I create a latch, that when the switch is pressed and depressed, the LED will stay on. and only go off after the next press and depress? The attached image is my working switch button. Regards Marinus

Hello I'm quite new with GT Designer 3. I'm writing code for the GOT2107 HMI. I have a few push buttons that works fine when pressed the switch lights up as you touch the switch. But now I want a latching switch. Every time the switch is pressed the light on the switch should alternate. How do I get a switch's lamp to stay on after pressing it? Thank you Marinus

Micrologix 1400 recording off time of a DI
Ryandevlin17 posted a topic in Allen Bradley / Rockwell Automation
Hi, I'm pretty new to allen Bradley and wanted to know if there was a function that could help me out. I have a rotation sensor which feeds back to the PLC via a digital input, once every half second or second once machine is up to speed - I want to record the off time of this DI (how long it is off between pulses, essentially how long it takes for drum to rotate once). Is there some way to record this time and use this value for compare logic? any help would be greatly appreciated. PLC: Micrologix 1400 series B RSLogix 500 version 11.00.00 (CPR 9) -
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

Modbus address register exchange between Melsec-Q series PLC and ME96SSHA-MB Power meter
RV3.0 posted a topic in Mitsubishi
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. -

Hello everyone! I'm the new of site. I have a PLC Mitsubishi Q03UDE and want to latch data of D register. I've set the latch data from D500 to D580 in PLC Parameter, you can see it in the picture i've attached. It seems work well when I turn on PLC everyday, but when i turn off PLC for a few days ( about two or three days ), all the data goes to 0. So can you tell me what's the problem ? My PLC have no battery. Thank you in advance for your help.

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

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. -
Hi all, I am a newbee with GX works2 and I got stuck in the change of developer software. Hope anyone can help me to find a easy way to solve this. I got a program in GX IEC Developer 7.04 where I have Latch(1) on all D register I am using. PARAMETER - PLC DEVICE - Data register is 0-13312 and SystemVariable are from 3000-13311. I have not find a way in GXWorks 2 to allow the same. I figure out I need to change variable type in FB to VAR_RETAIN but how do I solve this for Global variable? Do I have do give all the variable fix addresses?

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

How to hold the particular value and memory of program even in power off

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? -
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
