Hello to everyone. Nice to meet you all. How are you? I hope you are doing well. I’m developing a program with the purpose of make something similar to a pulse train in the output. However, sometimes I need the output to be a “positive” pulse and sometimes a “negative” one. By positive and negative I mean the polarity in relation to the pulse train source. I’m trying to use a pair of bits in order to switch between the two choices of polarities. I attach a simplified version of the ladder diagram I’ve made. When I thought about the logic, it seemed logical to me, however, it isn’t working as supposed. SM0.4 is a pulse train source. According to the software manual, it is a pulse train with 50% duty cycle and a cycle time of 2 s. That it to say it says at TRUE for one second and return to FALSE for another second. I assign the value of that variable bit to the M0.0 memory bit. I get the negative version of the pulse train logically negating it in the Network #2. I assign the value of two inputs, I0.0 and I0.1, to other two memory bits, M0.1 and M0.2. · When both inputs are in a FALSE state, the output stays FALSE, disregarding the state of SM0.4. (Case #1) · When I0.0 is TRUE, M0.1 is TRUE. However, Q0.0 stays at FALSE no matter SM0.4 is TRUE or FALSE. I attach a pair of pictures. (Case #2) · On the other side, when I0.1 is TRUE, M0.2 is TRUE. In this case, the output shows the correct behavior. It is the negated version of the pulse train source. (Case #3) Has any of you experienced something similar? Is there a better way to execute my purpose? I’m not executing the program, just simulating it with KincoBuilder from Kinco. However, it has always worked fine for me. Thanks for you attention. I look forward for your responses. Kind regards!

Hello PLCmaniaccccssss, What is the unit of time in 'average time for the channel -1' (D8284) while programming for analog inputs? I have moved k10 to D8284 in my program in gxworks 2, does that mean the time average will be taken for 1Sec or 10msec or any other time unit??? I require this to eliminate the flickering of the input from the load cell transmitter. Thanks and God bless!!!

Hello all, I have a temperature sensor with a reading range of 10F to 212 . The input card I am using is an Allen Bradley 1734 IE8C 8 Channel Analog current input. The current input values are 4-20 mA. Currently I have my raw low at 4000 and raw high at 20000. Can anyone explain how do we go about selection of this values ? I found these values in the configuration tag of the input card properties. Thank You

CP2E and Analog In/Out (CP1W-MAB221) setup in CX-programmer "settings"
Stefano A. posted a topic in CX-Programmer
Hi, I have a CP2E PLC (CP2E-N30DRD) with an Analog In/Out board CP1W-MAB221. I can't find a method to setup it correctly (the ERR LED is fixed in ON state). The "W516 (Section10) CP1L-EL_EM ANALOG OPTION Boards" manual says to "set the baud rate of the relative option port at 115200bps in Toolbus mode.", however in CX-Programmer , under "Settings" and "Serial 1" tab there is not such protocol. In w614 (cp2e software manual) and w613 (cp2e hardware manual) I haven't found any other tips. Can you help me please? Thank you. -
NX1P2 Motion Control change output device with code
BrunoRamos posted a topic in NJ Series / Sysmac Studio
Hi everyone, To explain the problem a little bit: I have 2 systems that are equal, they have 1 PLC, 1 Inverter and 1 Servo Axis (Image01). The devices are connected via EtherCat. The thing here is tht in these systems the PLC and Servo Axis is the same but the inverter is different. My goal is to have the same project on both systems and depending on the inverter detected use the correct program. What worked: If I add the 2 Inverters and 2 Servo Axis on the project on different nodes (Image02), I can detect which is present using the variable _EC_EntrySlavTb[n]. My issue is that if I want to make more replicas of the systems using different inverters I will eventually hit the Axis Number limit for the PLC while in reality I am only using on Servo Axis at a time. What I wanted: I would like to be able to control 1 Servo Axis with 2 different inverters (only one active per PLC) (Image03). What I tried: The axis parameters can be set using a variable of the type _sAXIS_PARAM, however it seems that the option to change the axis basic settings is not available (Manual: NJ/NX-series Motion Control Instructions Reference Manual (W508) page 5-58) (Image04). The axis basic settings is where the definition of the output device plus control words are set (Image05). Is there a work around to solve this issue? I would really like to avoid having to manually change the output device for the Servo Axis every time I make an update on all the systems. Best Regards, BR -
Hi guys, So I found that CH2 on Q68ADG is abnormal. Whenever I short the termination, the digital value goes max to 4096. Input is set to 4-20mA with normal resolution. I tried to simulate 4mA-20mA but still same result. Does this mean the CH2 is damaged? Equipment at site is normal and give 5mA signal. Thanks!

Hello, I am new to the programming of logic controllers. I have a Chinese FX3U 24 inputs and outputs with analog in and outputs. I am trying to teach myself the basics of the programming but I am stuck at the analog part. what I am looking to do is create a program so that when a 12v battery bank voltage drops and rises it can trigger other outputs. I have a voltage divider which outputs 1/5 of the input. Thanks for your help in advance. Ben.

I have an analog output card 1734-OE2V. As a default, there is selected fault mode as 'Go to Low Clamp'. I am using output range -10V to 10V. What is the value for Low Clamp. Is it 0V or -10V? If I want it to be 0, do I need to select 'use fault value' and set the fault value to '0'.

Hello! I was trying to configure an Temperature Sensor using the Analog Threshold Trigger to parameters and output activation but, when I put this function on the program, there's just input point, on the output there's no way to link to an DO, when I select the other one's analog function's to see, they all have the same problem. How can I fix this?

Hello there, Today i have commissioned my first project with OMRON make PLC. Model: CP1L-EM40DT1D. (CX-Programmer) I have 2 built in 0-10V Analog Inputs on the plc. for analog input no-1 i get the digital value of 0-1000 in specific plc register address corresponding the 0-10V. (Factory setup) But today on site, i have noticed that some miner value of 0 to 50 is always coming and fluctuating very fast in that register, however the transmitter are genetaring 0.0V only (I have checked using digital multimeter with high precision) PLC and Transmitter are already grounded and all the cable connections are tight as well. so how to overcome this high fluctuating value ? is there any setting to filter the input ?

I need to use digital outputs of PF527 drive. Controlling the outputs, it does not do anything. Relay outputs are working fine, but opto outputs do not work. For the outputs, there are relays connected, using pin 6,7 and 17.

This is a 1756-IF8 rev 1.5 Analog Input module. This has happened a couple times where the Module Input Data, (not mapped), goes to the high limit and freezes (Data Monitor data is static). Plant operators pointed out the trending wasn't accurate. There is no fault on the module, no yellow triangle on the system tree for the module. The Module properties show no faults, and RUNNING. I have done a "Reset Module" both times, (Module Properties - Module Info tab), while monitoring the module data. As soon as it resets, instantly the Data Monitor starts showing live data. I'm going to try and replace the module at first, but I have some concerns. Has anyone run into this before? I can't seem to find any information on the "Reset Module" animation, and what it actually does. Any information, (or where to look), would be appreciated. I don't like to hot swap, but I believe I will need to in this case, (utility). Will the current properties, e.g. scaling transfer to the new module? Thanks Dave Redman

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.

M221C40R + TM3AQ2 analog output
Boushard posted a topic in Modicon / Telemecanique / Schneider Electric
Hi guys, I'm in another project with another brand on PLC and this time I thick I hit a pretty solid wall. Long story short, I need to change a -10 +10v signal send to a DC motor drive based on a "recipe" selected with a 10 positions camswitch. I've never programmed schneider PLC, except the zélio one who are pretty simple to understand. Apparently Modicon are much more complex to program with the knowledge I have. Is there documentation available somewhere I can use to understand how to code analog output. -
Evening, I struggle with simple task... I need to activate PLC Output at the specific time of a day. I`m using GSV to obtain PLC time, data is being moved to DIN[7] registers. Then I have three EQU (Hour / Minute / Second) and at the end of rung there is OTL for output. Rung below I have two EQU (Hour / Minute) to disable output at different time - OTU. However every time OTL is energised , OTU on rung below is fired too. What am I doing wrong here ?

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.

Using NX-PG0232-5 to control Stepper Motor (NJ PLC)
ragzz1995 posted a topic in NJ Series / Sysmac Studio
Hello, I need to control a stepper motor(have stepper driver) using NX-PG0232-5 with NJ301 PLC. The function is simple, i need to run the stepper motor continuously at a specified velocity. So, in NX-PG module I've made the settings (Ch1 output mode as "Velocity continuous pulse output") and given the tags to IO (as shown below, sorry i'm not able to attach image). I've also added the initialization program to switch on the vfd. Now to move continuously i should should just give speed in pps in "PG_Ch1_Command_Velocity" right? Ch1 Controlword Control word 1 W WORD Ch1 Switch On Switch ON for pulse output 1 W BOOL PG_Ch1_SwitchOn Global Variables Ch1 Enable Voltage Start turning on the power for pulse output 1. W BOOL PG_Ch1_Enable_Voltage Global Variables Ch1 Quick Stop Immediate stop for pulse output 1 W BOOL PG_Ch1_QuickStop Global Variables Ch1 Enable Operation Start operation for pulse output 1 W BOOL PG_Ch1_EnableOperation Global Variables Ch1 Fault Reset Reset errors for pulse output 1 W BOOL Ch1 External Output Aggregated data of external outputs for pulse output 1 W BYTE Ch1 Command Position Command position of pulse output 1 W DINT PG_Ch1_Command_Position Global Variables Ch1 Command Velocity Command velocity of pulse output 1 W DINT PG_Ch1_Command_Velocity Global Variables -
Good day all, I recently working an assignment to read analog data from sensors. I connected everything just as what the manual for sensor stated. My PLC is DVP20SX2 and the sensor data i want is 4-20mA. The analog sensor has two wires, Analog Output + and Analog Output GND. I connected the + to I0+ and the GND to the VI0-, but when I work online using the ISPSoft, I can't get any data. My doubt is the wiring. Can anyone guide me on this? Is my wiring wrong? does analog works the same as digital, where we have to connect to same COM?

I have a Base tag of BOOL logic that will not activate the MOV output. The Base tag is paralleled with an Alias tag for a NO pushbutton. When the pushbutton is actuated it produces the desired output. Has anyone encountered this issue from a togglebit base tag before? Why would a base tag produce a different outcome from that of an alias tag that function properly?
