Hi, I have inserted new RTD module into in my SLC500 as replacement to defected RTD module however the module LED is enabled but the channel LED's are blinking. I have checked the following: In the advanced I/O configuration the module configuration is shown as expected In the data file word format it is not corresponding to the channel preferences What should I do and how to fix the word bits?

Hi there! I have S7-1200 controller connected to a Comfort Panel. The machine has some pressure and temp sensors, as long as many valves and other stuff. I generate a daily datalog with some of those variables but, the thing is, I've been trying to figure out how to show these data in the HMI without using a trend viewer. I don't know if it's possible, but I want to be able to see what valves were open (for example) the day DD/MM/YYYY at HH:MM:SS, using the generated data log, kind of knowing the state of single bits at different past moments. I've been searching the web but I didn't find something exactly like this, don't know if I'm doing it properly so I'd like to know if you have done this or you can throw some light on the topic. Thanks in advance and hope you can help me!

Omron NJ/NX to AB Ethernet/IP String Data type exchange
Brooksy posted a topic in NJ Series / Sysmac Studio
Have been able to exchange data types of BOOL, INT, DINT & REAL between Omron NJ/NX CPU with Allen Bradley Logix CPU's with Ethernet/IP using the CIPUCMMRead & CIPUCMMWrite instructions. I now have a need to exchange "STRING" variable types. Have tried varions string lengths in the NJ without sucsess. AB default string length is 82 & Omron 256 but I think the difference is the length headder that AB has with within their String Tag type. I know I could convert my strings to an array of bytes & sent them this way, but was looking for a solution to sent them as native strings. Hope someone out there has done this & can share their leg work? -
Hi I'm trying to set up Modbus RTU communication between FX3U PLC and a weigh module. I would use the ADPRW command using 0X03 to read the 16 bit Holding Register but in the weigh module the Data Address/Holding Register of the value I want to get is 400047 - 400048. How to translate the value in 16 bit? Thanks, Fabio

I am new to PLC programing, I want to connect FX5U and MR-JE-_C via CC-link. When I connect FX5U and MR-JE-_C directly everything works, but when I connect them in HUB (I need to use HUB because later I want to connect GOT2000) I am getting error 86.1(network communication error) on amplifier. Previously I set up IPs shown on pictures below, now sometimes works, sometime doesn't work and sometimes works for 30 seconds and I get same error. Did I miss something? I don't know what to try else.

Hi there! I need to implement a data logging that saves the log in a USB storage for a machine and just started searching for some info about data logging in NB HMIs. Up to now I'm clear about using the Data History function and the sampling method I'll be using but I still have some unclarified doubts about this. 1.- The data log should sample the value of, let's say, a couple of words, each second for an entire day (6:00 am to 6:00 am). NB's manual doesn't say a lot about Storage Type and Buffer Storage in "Save Data History" tab. Does "daily file" mean It deletes the .CSV file daily and it generates a new one? If is it, at what time does this occur? Does "single file" mean it generates a file and won't get deleted? Does this mean the sampling stops when completing the first one? Is "storage period" used to keep the file after the next log begins? 2.- Is it necessary to display the element in order to make the log work? Or can it be placed in a random screen you only enter once a day? 3.- In the "Channel Properties" tab. If I need to get the binary value of a word, do I need to set the max. limit to 65535? 4.- I asume that "Sample points" value doesn't matter when selecting Continue sample mode. Am I right? Thanks in advance, any help is appreciated.

Hello, I am trying to log data using GT Designer 3 and I'm having no luck. I found some sort of online documentation and even going through the myriad of steps still find my self unable to log anything. I am using the melsoft project navigator and GX Works 2 to simulate the logging of just one 16 bit signed word with a constant value. As logging data is clearly not as simple as just specifying D100 or D200 as the devices you want to log, I am hoping someone else on here has some experience on this matter and can help me out. Thanks for any help in advance.

Hi, I am looking at reading an ultrasonic sensor value through IO-Link, using a Omron NJ501-1320 PLC connected through EtherCat to a IFM AL1332 master with a Wenglor U1KT001 Ultrasonic sensor. I have managed to read the 2 outputs of the sensor using this: Output_1 := TestABit(USINT_TO_BYTE(TxPDO_input_byte_1_6000_02),USINT#0); Output_2 := TestABit(USINT_TO_BYTE(TxPDO_input_byte_1_6000_02),USINT#1); But cannot read the ultrasonic sensor distance value, this is what page 2 in the manual says: Measured Value in 1/10 mm 2…15 14 Bit 300…4500 Octet 1 Subindex 3 (LSB) 2 1 Bit Offset 7 6 5 4 3 2 1 0 I tried a couple of conversions but couldn`t get the distance reading. Any ideas? Help appreciated.

Hi all, I am currently having a project of polling data from PLC CJ1M using Advantech ECU-1051 IoT gateway which support rs-232 serial connection (Host Link) to poll data from the PLC for data acquisition and monitoring, I would like to use peripheral port since rs-232c port is used for HMI. However, I am currently stuck at make the connection between those two devices. I did setup same transmission configuration between them (baudrate, Unit number, start/stop bits,...). Is there any configuration that I have missed to make the communication works?

Missing components in module list when configuring Mitsubishi CC-link
kimdinhthaibk posted a topic in Mitsubishi
Hello everyone! I've installed GX works 3 according to the instructions in "https://plc4me.com/gx-works3-v1-308q-mitsubishi-full-real-100/". I don't get any errors, I can run the PLC and simulate completely OK. In the communication test, when the configuration is missing some components in the module list: Input, output, I / O module,... (https://ibb.co/ZVMcmQn) I hope you can answer for me? -
Good day everyone, before I start asking my question, just want to let you all know that my knowledge with PLC is not that good. I'm still learning on how to do it. So currently I'm working on a project that trying to obtain data from Omron PLC. I was told that I can't touch the Omron PLC program or modify it. That Omron PLC is connected in an isolated network within a router. Other than adding Network Card on the device, can I use another PLC (any brands) to get the data from that Omron PLC through the router? The communication protocol using here is Ethernet. Can i just tapped into the network and take the data with that way? Or the other method I'm thinking is that, the Omron PLC will feed the data to a server, can I just obtain that data from server by using OPCUA? I heard there's some PLC that have the OPCUA function, I just make my PLC into the cilent and request the data of that Omron PLC from server through Ethernet. Is this possible? Please let me know whether my method works or not, thanks in advance guys!

Hello everyone, As the title suggests I am trying to display on a GOT1000 the real time frequency that the inverter is running at. I have attached my CC-Link settings and the associated programming as well. I tried using the example program from Mitsubishi but I got lost. From my understanding I should be seeing the output frequency in W3C4 however, I am not receiving any data. Any help would be appreciated.

Hello all, kinda lazy question, but I'll rather ask, before I'll went to deep into HMI scripting. Because of a design of CC link, there are RWr and RWw Is there any simpler solution for displaying value stored in PLC, while also letting HMI operator change the value and save it to PLC, than scriting in HMI? hope it makes sense to you thank you in advance

The CC-Link system on a machine has been intermittently dropping out. Normally the Link Scan Time runs at a solid 87ms. When the system "drops out", the link scan time will increase. Sometimes double, triple, or go up 10x. It happens when the machine is running or when it sits idle. There are 33 stations on the network. The same stations do not always fault but sometimes all of the stations will fault at once (as seen in the attachment pictures.) We have changed the main QJ61BT11N, the processor, the Q62N power supply, the main backplane (base unit), all cards on the main backplane. Is it possible for one station or one of the cables to create a network wide problem? Any ideas thrown at us would be appreciated.

I'm editing an old program for a customer that has a zillion user-defined data types. Scrolling through the list trying to find a specific type definition is taking way too long. Is there and easy way to find a specific data type definition? It would help if I knew how to collapse the view so I don't have to scroll through each member of every type. There doesn't seem to be any right-click menu items that would collapse the view.

Hi! I would like to ask how could I send data from PC to CJ1M PLC, by SCU-41 module and RS232 cable, in order to activate an actuator (LED)? In my environment, I have a sensor that sends data from PLC to PC (I'm checking data, "HelloWrld" with Putty), with this configuration: And I have another section where I want to read the data from the PC in ordr to activate a LED I would like when I send for example a letter 'a' trough Putty, the LED activates. How could I do that? Thank you very much!

Conversion from Integer to float and vice versa
Rajesh Anand posted a topic in Allen Bradley / Rockwell Automation
Hello, I'm using RSLogix 500 application for LAD programming. I would like to convert the float data type to integer data type and vice versa. I tried with the COP instruction as some had mentioned in other forums, but it was not working. So any suggestions on solving that issue would be helpful. -
I'm working on simple structured text program which takes in DWORD values, does some math on them and then outputs in DWORD type. What data type should I be using and how can I make this work? This is one of the lines from the code(everything DWORD) and I get 'operator not supported by DWORD data type' XPos3 := XPos1 + (2*XIncrement);

I have an IAI servo that was sent to us with CC-link protocol. I have never in my life used cc-link and can find very little on the topic on integrating with an Omron CJ CPU. I am curious as to whether this has been done, or is even possible given the protocols Omron works with. And if so, what did you have to do to get the PLC to communicate via CC-link. Thanks in advance for the responses!

Anyone know how I can create a log of results from a Cognex vision system? I have 3 cameras that look at various thinks... clip presence, clip height, clip angle. There are 2 clips per part and 6 parts per tool. This makes it hard to zero in on what I areas I need to tweak. Thanks! P.S. I've heard that maybe their OPC Server could do this but I don't have much experience with it (actually I don't have a whole lot of vision experience at all). From what I've briefly read, I just install the server, set up the tag within the server, start it, and I can just drag and drop the tags into an Excell cell? If this is true, this just gives me another way to read the values. How can I create a database or log of these tags?

Hi all, I'm enhancing an Ethernet IP driver but only just learning the ropes in terms of Allen-Bradley PLCs. I'm presently focussing on that part of the driver which specifically supports SLC/500 & MicroLogix 1400, for which I have one controller of each type for testing purposes. I can already cater for a range of standard file types: integer, float, binary, input, output, string, counter, timer, control, status, and this is working well. However, by working with RSLogix500, I can see that there are other data file types which can be hosted in these controller types (dependent on model) and, indeed for test purposes, I have actually created instances of them as follows: ASCII (at A21, 20 elements) for both SLC & ML1400 Long (at L22, 10 elements) for ML1400 Message (at MG23, 8 elements) for ML1400 PID (at PD24, 4 elements) for ML1400 Programmable Limit Switch (at PLS25, 3 elements) for ML1400 Routing Info (at RI26, 3 elements) for ML1400 Extended Routing Info (at RIX27, 3 elements) for ML1400 Now, the driver obviously uses standard DF1 PCCC data types (see below) to read/write individual elements/sub-elements of the file types that I can already support -- and I can see that there's a file type listed below for ASCII. •80 to 83 hex: reserved •84 hex: status •85 hex: bit •86 hex: timer •87 hex: counter •88 hex: control •89 hex: integer •8A hex: floating point •8B hex: output logical by slot •8C hex: input logical by slot •8D hex: string •8E hex: ASCII •8F hex: BCD However, my question is this: since there are no hex file types corresponding to non-elementary data types such as L, MG, PID, PLS, RI and RIX, what file type do I specify in my DF1 PCCC packets to read/write the elements/sub-elements of these six data types ? Thanks in advance.

Data entered into the PLC D memory table does not end up in the instructions and I'm not sure what I'm doing wrong. For instance I want to use the CP1W-DAM01 to change a duration value. I have a symbol setup using the corresponding address setup so that it ties in with my timer but the data does not transfer even thought the value shows up in the table. I'm also using it for parameters on a scale instruction, same issue. Any ideas.
