I have an 8 point analog input card on a rack with a SLC 5/04 CPU. It has been in operation for 20 years or so. There have been some power problems at site lately and ever since they fixed them I have been having issues with 3 of the 4-20mA circuits on this card showing open circuit. I have had my meter on them when they show open circuit. The signal reads 3.96mA, just below the 4mA minimum and boom, the machine goes down. Is there a way to adjust this tolerance?? I don't think there is anything wrong with the 3 transmitters so the error is just a nuisance.

Hey there forum guru's!!! I am trying to read through the manuals for an NX-HAD401 High Speed Analog Input Card. It is not very clear as to where you assign your variable in order to grab a channels analog input value. Can you point me in the right direction? I am thinking it is in the "Analog Input Values 1 to 10" and if so why is it set up as an array? Is it because it takes the average of the samplings and uses the result as the channels input value? I am sure I will have more questions but this may clear up a few.

Hello all, Thanks for the forum which has provided me with a lot of help overtime. I'm posting my first thread since I can't seem to find an answer to my issue. I'll quickly explain the situation: I'll be installing a RTD sensor to a GE Fanuc IC200ALG264 analog input module using a 4-20mA converter. Everything is fine except I can't seem to understand the polarities of the Fanuc inputs. I'll explain better: the module has an IC200CHS022 for the terminals, 15 terminals total, and the manual is reporting a "number" and a "connection" for each terminal. Now, the "number" seems to correspond to the visible pin of the terminal. But the positive and negative symbols are represented on the "connection", which I can't seem to wrap my head around what it means. Attached are abstracts from the manual and a photo of the terminals. Please tell me where to connect positive and negative outputs of the 4-20mA converter. Thank you.

M221 & SoMachine Basic - ANALOG INPUT SCALING
horvatmiha posted a topic in Modicon / Telemecanique / Schneider Electric
Hello! I am new at PLC programming. I am using TM221CE16R PLC with TM3AI8 analog input module and SoMachine Basic v1.6. I am trying to scale analog input value. I am using 4-20 mA pressure sensor. I managed my wiring so that I get raw values in SoMachine Basic. But I don't know how to scale these values to usable values. My sensor works in range 0 - 16 bar. What is best way to get values? Is it PID function block or multioperand function block using equations to get range 0 - 16? I will appreciate your help. Thanks in advance! -

I'm using simple function block, one input and one output, like in this example: Problem I have is how to call function block and use inverted (NOT) value , ie instead 5.01 I need to use NOT (5.01) . Of course I could create new symbols that are inverted values of actual inputs but i'm trying to avoid that, number of addresses is significant.

Hello Dear Colegues. I am using historian 7.0SP6 (enterprise license). I have installed OPCAE collector to collect alarm and events data from a project in cimplicity in order to have an historical data of it. Also I have checked the Historian OPCAE interface box in the cimplicity project´s properties. The problem is that when I try to see the tags from OPCAE collector on historian administrator I have the following error "No Tags Matched The Criteria You Have Entered. Please Try again or Cancel your Search". Also, I am not able to see the "last 10 alarms in the collector´s configuration tab. What could causing this problem?

Hi, how can I get rid of those alarms with status I(O) ? They are simply something like duplicates and they re making it hard to read the logs.

Comparison of Mitsubishi, Allen Bradley & Siemens
Gibblet posted a topic in General Topics - The Lounge
Hi all, I am in the process of doing a project for some school work and need to do a SWOT analysis of the latest modular PLCs from Mitsubishi (R series), Siemens (S7-1500) and Allen Bradley (ControlLogix). So I thought what better way than to ask the people on what they think are the pros and cons of each! Thanks for your responses in advance! -
I am using a Label as a Message Display with Resource Group. I want to do the same thing with my User Alarms, I do not like the Alarm View Popup.....The image is how I assume it needs to be setup. It compiles and downloads without fault, but messages do not display. Any thoughts on what I am doing wrong? I could retype all the User Alarms in a Message Resource folder, but I have a lot of User Alarms.... Thanks,

hello everyone , I am involved in the development of an industrial product. It has a 24 V On / OFF output signal which will be read by a PLC digital input. It could be Allen Bradley / Siemens . Can anyone tell me what would be the approximate values of the internal pull ups and pull downs? where can i find this? Thank you for all the help. Regards Sha

Frozen Analog Input on Compact Logix
Dan Truitt posted a topic in Allen Bradley / Rockwell Automation
This is a bizarre one... CompactLogix, 1769-IF8 with 1492-AIFM8-F-5 wiring system. My client has reported several instances where one of his flow rate displays is frozen at its maximum value. Each time, I have gone to the site, found that the value in the analog input tag is at full scale, and measured more than 20mA at the input - as much as 28mA! I measure it using a clamp-on meter and I measure it at the input module (1769-IF8) and the external, pre-wired terminal block (1492-AIFM8-F-5). I cycle power to the PLC. No change. I cycle power on the transmitting device. No change. I disconnect and reconnect the input (signal wire at the module or the terminal block) and everything goes back to normal. This has happened on multiple channels on multiple input modules and with two different types of transmitters. I didn't install this system, but it seems to have been done properly and it had been running fine for many years. These problems just started happening out of the blue. Has anyone out there had any similar experience? This is a new one for me after more than 25 years in the business. -

Is there any reason not to have input and output modules on the same rack as the processor and Ethernet cards? We have RIO’s and sometimes have networking outages, I want to move critical IO to Rack0 the same rack as the processor, is this bad practice? I've seen architecture for BMS that only have Ethernet cards and processors in Rack 0...

Hello, I used a Schneider Electric SR3B261B PLC to create a trivia machine (as I call it). Basically 20 buttons that let contestants ring in to trivia. There is a display that shows the number of the person who rang in. It works pretty well unless people press the buttons at exactly the same time. Then it shows 2 results at the same time. Usually resulting in a display of 18 when really it was 12 and 14 that rang in, for example. The PLC has options for: "Adjustment of the basic cycle time of the module." and "Type of Hardware Input Filtering." Which I assume would make the PLC operate faster and avoid two inputs triggering at the same time. If I change the setting and update the changes do not keep. I appear unable to change it past 20 x2 ms and slow (3ms). Is that a correct assumption that changing this would fix it? Why can I not change this? Is it because I have so many inputs (14 or so) and Outputs (16 or so)? or because my program uses nearly all 240 lines of ladder logic allowed? What can I do to fix this? Emerald

Is it possible to view the values / states of all inputs, outputs and workbits (e.g. 64.00 through 64.15 on Omron CQM1 PLC) on a single screen or control panel within CX-Programmer software? I'm trying to troubleshoot some ladder logic that I wrote and need to know the values of 5 or 6 inputs/outputs/workbits simultaneously. Having to scroll up and down through my ladder logic repeatedly does not work well with code that changes state every 5-10 seconds or so. Any help is welcome.

Anyone have experience with the Peak to Peak hold function on Keyence IL-1000 amplifier? I have an IL-030 lase head running off it and I want to utilize the peak to peak hold function. I connected the red wire from a generic 24VDC, 1A, power supply to the IL-1000 Pink/Purple (timing input wire) and the black wire from the power supply to IL-1000 Blue (0V). I have a 24VDC, 5A, power supply connected to IL-1000 Brown (10-30V) and IL-1000 Blue (0V) to power the IL-1000. What I thought might work is to plug the 24VDC, 1A power supply in and out of an outlet to trigger the timing input for the P-P hold (similar to an on/off button). But it's not doing anything. I am not an electrical guy. Any tips here? Thanks,

PLC-5 BTR setup screen for manalog input module
jrsiscool posted a topic in Allen Bradley / Rockwell Automation
HI I'm using PlC5/20 when I click on setup screen on the BTR block (to view the analog input configuration) i find the following message: No modules exist in the IOconfiguration for this R/G/M however the analog input signals is running properly....i just want enter the setup screen for configuration. I'm assuming that I need to enter I/O module in the I/O configuration? Can I do this without taking PLC to Program mode? -
Hi All, I am new to the forum and new to programming PLC and like every newbie I have a lot of questions - Brief History of me - I had been a Manufacturing Technician for 20 years and recently got my BS on Electrical Engineering and now working as an Equipment Engineer. The main reason that got me interested in PLC's is my degree, the field that I would like to get into and a recent problem that arise at work. My experience with PLC is very small in programming, some in TS I/O- However I had been studying by my self to the point that I built a test bench to understand it better and in the future create different project for learning purposes Currently I am putting together a tool Alarm delay program - Basically my exhaust sensors trigger an alarm (input signal turns OFF) before its send the signal to my tool for abort, I want to create a different Alarm which will cause a different response from my tool and delay the original Alarm by 10 min and then trigger the original Alarm - PLC = Panasonic FP0C14RS Reasons: Create a different Alarm: The response from my tool to this alarm will allow me to return my material back from the tool and put it in a safe spot. Delay the Alarm: Use a timer to perform this tasks - This the time that approx. it takes the to return the material. Trigger the original Alarm: I need to know which sensor was the problem in order to properly TS- So after my timer is complete - I want to know which sensor created the original Alarm My Current problem: I created the LD program, and while the original alarm stays OFF the program works fine - but since my exhaust sensor are always on - If my original alarm is trigger for a few seconds, just enough to start my Delay Alarm: I dont have a way to know which sensor trigger after my Delay(Timer)is complete, I reset my relays in order to be ready for new alarm. Please provide feedback to my program - I know currently is not the best way or efficient way to do this and there are better ways, but my plan is to get it to work and then later revisions improve the way the program can be written Thanks in advanced for your feedback and help Exh_delay_inv_rev1.pro

RSView32 Alarm Suppression on Startup
python01 posted a topic in Allen Bradley / Rockwell Automation
Every time my rsview32 project starts up all the alarms which are set up to alarm on 0 tag value show up on the screen even though the bit in the PLC is not in alarm condition. I believe this is because the communication between RSView32 and PLCs is not established yet and the tags are seen as having value of 0 in the HMI. Is there a way to disable or suppress these tags at startup to give enough time for the RSView to update the values so the false alarms are not being displayed? -
Have looked right through the manual and cannot find anything. Finish up with a scrolling line. Ideally I would like to have an alarm page and alarm history page like the one in the NS screens. Any thoughts please?

Hi, I working on reading impulse from the input. I am using M8000 as a contact, on the coil [C235 K9999] and it is working fine on the lad, but the problem is I need to applicate sth like that in structure ladder but I dont know how. I found function on the image below but it is for FX3U. I know that 2-phase 2-count input use OUT_C(for example EN True| CCoil CC251| CValue K0) and then DMOV(for example EN True| s CN251| d D100), so is there any method to read impulses from the input? .Thanks in advance. PS I have Mitsubishi FX3G series.
