Citect Dynamic Pages With Genies and Supergenies
mondi posted a topic in Modicon / Telemecanique / Schneider Electric
Hi All: I am new to Citect and looking for a way to create 1 page that has 25 valves (genie that pops up a super genie) and some analog genie/super genies. What I want to do is create 1 page and dynamically replace everything when someone selects a different rack in the system. I have 4 systems that have the exact same equipment times 10 so I want to avoid creating 40 different pages. Can anyone help with some ideas on how I can accomplish this? Thanks M -
Hi, I am new to the forum and relatively new to PLC's and I am working on a project that controls several pumps and I would like to install a off delay timer that can be adjusted on the HMI for individual pumps, is this possible ? I am using Siemens TIA Portal V13 and I have a KP1200 comfort panel along with a S7-1500 PLC Any help would be greatly appreciated

Could anyone tell me that how can we use/recall Q bit of timer in FP0R. As we can use DN/TT in Allen Bradley

FB_TIMER_ON_OFF The FB is a part of RTC library and implements a timer, based on RTC, for ON and OFF a control bit, e.g. to turn ON/OFF a load in the time interval, and can be easily added into your program in desired quantity. The FB is supplied with E (Enable) input, EO (Output to Control Bit), and can operate in one of two modes: HMS = Hours + Minutes + Seconds (daily timer) MDH = Month + Date + Hours (yearly timer) Each setpoint of ON and OFF time settings should be represented as Array of INT [0...2] type and contain a time data according to the chosen mode. Thus, for example: - in HMS mode: a control bit can be turned on at 02:03:14 am and then turned off at 06:04:17 pm, or turned on at 05:12:27 pm and turned off at 07:06:22 am; - in MDH mode: a control bit can be turned on 3th February at 02:00 pm and then turned off 4th June at 05:00 pm, or turned on 12th November at 03:00 pm and turned off 6th March at 10:00 pm. If the values of both time settings are the same, the FB output will not be activated. Supporting PLC CPUs: All FX Program memory: - 34 steps per each FB instance - 4 steps for entire project (reading from RTC) System variables: M - 3 bits (for entire project) The library is compatible with GX IEC Developer and GX Works2 software . https://plus.google.com/105445006108716761629/posts/Z4v4F11s4Bz

At work we have been having a slightly increasing number of instances where the Micrologix 1400 that is paired with a Panelview C400 resets values when we cycle the power. Originally we thought the solution was a bad battery in the ML1400. This was the case the first few times that it happened. However, we recently had one doing the same thing and when the program was loaded onto another PLC and HMI combo it had the same issue. So either the battery for both just happen to be bad, or there is something in the program that is forcing the values to automatically reset when the power is cycled. I cannot post the program on here but I can tell you that the tags that are being reset are only used in the PLC program once. There are six total that are being reset and they are the high and low range in an SCP function that is used to scale inputs. I will be testing the program myself in house on a bench setup, but I wanted to get this question out there as soon as possible in case it is not an obvious problem. Has anyone seen this before? Any suggestions? If I come up with an answer I will post it. Thanks.

Turning inches traveled per pulse (a real number) to inches per minute
487mcgill posted a topic in Allen Bradley / Rockwell Automation
I am currently trying to get my program to take distance traveled per pulse, which is based off of the diameter, and convert it into IPM. I am using RS Logic 5000 software. If anyone could help me get over this hump I would really appreciate it! -
Hi Can anyone help with changing timer values in a C40K using syswin and a host link3G2C7-LK201_EV1. I have tried clicking Editors, Data display editor and then T/C VAL. This then loads all the values into the display window. Double click the required Timer and a new window opens up with the value. Changing that value and then clicking ok and then writing the value to the C40K. This does not appear to change the value because if I then read the values back I still have the original value and not the one I changed it to. Hope this makes sense. I assume that it should be possible to change the values using this method. I can change the values using the hand held console

Greetings! I just have one question. Is it possible to get pulse time down to 5ms? I have only been using down to 10ms so far. Im using the M8011 timer memory. Thanks in advance! Best Regards Henrik.

Conditional increment after every five seconds
ritzspeed posted a topic in Allen Bradley / Rockwell Automation
I want to build a logic in ladder diagram in RSLogix 5000 v16/v17 where an analog output is intially set to 10%. Two analog inputs are continuously being read and being compared to some respective threshold values, and if any of these two inputs are less than their respective threshold values, the PLC has to increment the analog output by 2% every 5 seconds. The effect of the analog output increment is reflected on this two analog inputs. If both the inputs reached their respective threshold values, turn on an LED lamp. Let me make it simple to understand: Let A = analog input1 B = analog input 2, C = analog output initially C = 10 after 5 seconds if A < 22 OR B < 36, then increment C by 2% if A < 22, B = 36, then increment C by 2% if A = 22, B < 36, then increment C by 2% and if A = 22 or greater and B = 36 or greater, turn on LED lamp do this (increase C by 2 %) every 5 seconds until both the inputs are equal or greater than their threshold values, i.e. A = 22, B = 36. The analog output must be set at increased value until next increment is given I've tried this using timer, timer done bit, timing bit, enable bit all, but did not success. The PLC doesn't increment after 1st increment, my logic is faulty. Any help would be appreciated. Thanks :) -
I'm new to the Allen Bradley software and I'm trying to add 3 values together. I have found the addition block but it only allows for 2 values. Is there a way to extend the block or do I need to use the block twice? Thanks for your help

Hello, I need to set a 1 second timer in a TSX 572623 plc with pl7 pro, the question is that using %s6 bit (1 second pulse) the timer is not exact enough, the program is 98 kb, not too big I think, I use the %s6 attaching to a positive pulse auxiliar mark in one section of the program and i use this mark %M in the rest of the program, but as i said, it is not quite exact, measuring the time displayed in a HMI connected to the plc, 40 seconds in the program (displayed in a HMI), it´s 47 seconds in a chronometer, it is not exact at all as I said, how can I solve this problem, can anyone help me? Thanks

File Name: HHMMSS.cxf File Submitter: ParaffinPower File Submitted: 08 Dec 2014 File Category: PLC Sample Code FB to provide a simple long timer with time remaining outputs. Time can be entered in HMS (or just mins for example). Time remaining is normalised to HMS though. Uses 2 other FBs. Create instances of HHMMSS as required. Click here to download this file

Hi I need to program my fatek fab Plc with the following : . I need to detect between a single long input or a repeated second pulse. The idea is to control a window blind with two outputs of the Plc and two inputs (one for up, from a up switch and another for down from the down switch). the blind should go up until I maintain the key pressed. But when I make a repeated two pulse on the key it should go up automatically during a certainly define time (enough to completely open the blind). The same for the down direction. I need help on that.
