Hi All, I'm still quite new to Unity and Modicon PLCs. I have a PLC program running in simulation mode for development/test and I'd like to follow the logic inside a running block. I can't seem to just double click the function block while online to see it's 'inside' logic. Is there a way to inspect the inside of a running function block? How can I check and diagnose the logic a running function block? Thanks!

Stepper motor initialization and E-Stop switches
Neosec posted a topic in General Topics - The Lounge
I've been building a contraption with linear rails and stepper motors. It has an X, Y, and Z axis. I'm using Velocio PLCs to control the motors which seems to be work well so far. I understand these are not very common and my question are related to general motion control, not Velocio programming specifically. Since I'm new to PLCs, programming, and stepper motion I thought I'd ask for some input instead of trying to reinvent the wheel. I'm to the point in the build where I'll be adding emergency stop/limit switches and am wondering how to go about writing the program; if there's an "industry standard" way to go about it. I figure the PLC will check to see if any switch is active. If one is, drive the motor away from it till it's inactive and store the location. If one is not, drive the motor until a switch activates then back off a until it's inactive and store the location. Drive the motor to the other limit of the axis (the number of steps should be known) to activate the switch, back off and store location. Rinse and repeat for the other axes. Is my approach about right? -
I'm looking for some general information about different types of vibration/temperature sensors. What type, brand, model number, etc. will best fit my application. Scenario: I want to monitor the vibration and temperature of multiple motors and gearboxes for a large overhead conveyor system. If an oil leak occurs and temperature increases, I want to see a temp. alert via a HMI. If a something mechanical fails, I want to see a vibration alert via a HMI. I've looked into sensors that stick to the outside housing of the motors or gearboxes via a magnet. My concern is justifying the temperature readings. How accurate would a sensor that reads an "ambient" temperature be (compared to a thermocouple on the motor coil itself or some sort of probe)? Also, would the location of the magnet on the motor or gearbox drastically affect the temp. or vib. readings? Has anyone had success with a similar setup? If so, what devices did you utilize? Are these systems truly beneficial? I'm currently considering Banner's wireless products...

Hello, Im looking for the in built function blocks, but i cannot find it in the program files/ omron folder where the manual says (even with search for *.cxf), perhaps i dont have it installed, but where can i get them from? As i remember i downloaded cx-one from the official omron web page after login etc, so thats why i dont understand why am i missing the fb libraries What else place there is to find useful FB-s? Thanks!

Hi! Anyone can help regarding this issue. I'm not able to monitor the Motor Block that I have created. there's no error either in the output screen but i'm thinking what is the cause of not running in the simulation which shows the Motor Folder RED even it was compiled. thanks for the help! Note: I'm new in mitsubishi.

Hi, i want to make a function block which will contain a block GP.CPRTCL (for predefined comm protocol). GP.CPRTCL has an input "Un" who only receives constant (H,K). On input of my own function block i can set a constant variable, but inside block that variable isn't a constant anymore (GP.CPRTCL doesn't recognize a variable). Is there a way for receiving constant variable in GP.CPRTCL block ("Un") if it is in another block. Regards

Which one Baldor Motor is best for Industrial purpose like food processing?? Please suggest . -
Hi everyone, I need some help with my PLC programming. I am currently using a twincat 2 software and a Beckhoff CX 8090. Basically, the gist of my program is to send and receive data and datalog the input data received from the sensors and timestamp the received data for every 1 second. I want to create a boot up counter where it will count the number of times my data logging program has restarted(if it did). This boot up counter serves as a health monitoring check to ensure that my program is running perfectly and thus, not restarting randomly when it shouldn't. I am more familiar with structured text so if you have a solution, kindly post it in structured text form. Your help would be greatly appreciated. Best regards, DeadPool

We have a Panelview Plus 600. One of our panels is labeled "Motor Control," in charge of turning on/off different pumps. The problem is while the system is running, clicking the on/off button will not turn any pump off. When the system is shut down, the pumps can be turned on and off but not when the system is running. I'm trying to shut off one pump without shutting the whole line down. Any help is appreciated. Thanks.

There are a lot of instructions in function block that are missing the enable input that is present when programming in ladder logic, such as ADD or MOV. It seems to be very limiting. The only way around it that I know of is to write your own function block in ladder logic or statement list and use that. I seems rather limiting of a language if it relies on other languages for it to be usable. Does anyone know why the enable bit was left out in many function blocks when it is so useful in ladder logic? Pat

I'm having trouble with some very basic programming using function blocks. Specifically Connect Components FB programming, but I think it is a general, common application. Using ladder logic, it is easy to set a value based on the status of a bit. If the bit is false, move a zero into the variable. If the bit is true, move and 88.0 into the value. This relies on the enable bit of the mov instruction in ladder logic. Many function block instructions do not have enable bits. How would I change the value of a variable based on the status of a bit using function block programming? A real world example: You have a two position selector switch. If it is turned to the left, the drive runs at 0 Hz. (off) if it is to the right, it runs at 88.0 Hz. Or if you have a 4 position selector and want to select between 4 speeds. This should be a simple task, right? I've called the tech connect support line a few times and sent them a few emails and they haven't been able to figure it out. This is such a basic task. Thanks, Pat

Hello, The company that I work for wanted me to design and build a FIFO loader. For those who do not know what a FIFO loader is, it's basically a lift that runs up and down and filling up the magazine slots with pcb's. After I finish the mechanical part i'll try to program it by using a CPM2C - 20. I have already played with CX-programmer and learned my self a bit, for example how to program simple things such as AND and OR gates for controlling motors and lights. Really hard part for me was figuring out how to create a program that reads data from the encoder and use it to create positions which the motor will stop at, and i have not yet figured it out. I've been trying to google it without any luck, the only thing of real info i've got is a 650 page long pdf file or CX-Programmer manual which is hard for me to read since i'm new to all of this. Would be great if any of you people got any source or maybe a manual which are easy to understand for new beginner like myself. A bit about the program i would like to make: The FIFO loader will have some buttons for selecting different programs, lets say you press first button to select "program 1". Then the machine should move up and stop at posision "50" (there are 50 slots on PCB magazine) after it gets signal from pneumatic actuator (which will be used to shove pcb inside the slot) its should move to position "49" and so on.. If FIFO loader is located at "home" position and you press second button to choose "program 2", then it will move to slot "49", wait until it gets loaded, and continue to slot "47" and so on.. The meaning of this is to make a loader which can select a program to fit pcb's with different size of components.

Multithreaded C++ into function blocks - PLCOpen
EinarM posted a topic in General Topics - The Lounge
Hi there I'm an embedded software engineer mostly programming C/C++ in Linux and have very little knowledge of the PLC environment. Recently my attention was diverted towards integrating C/C++ (Linux software) into PLC and then presumably as a function block which is supported with something called PLCOpen. Is that right ? How is multithread support in PLC in general ? and/or with the these function blocks or what ever might become instead when integrating/porting C/C++ code into PLC. The current situation is purely embedded Linux environment with open-source 3rd party userland that our code relies heavily on. How feasible is to port such environment over to PLC (given that the system supports it) ? I've been looking into B&R Automation Studio 4 and having a hard time to establish concrete feeling on how difficult/easy it is to port the code. Hope anyone can give me a slight insight into this. Kind regards Einar -

How to take single bit form input WORD by Structured Text? Can i write somethink like: inVar[i]

Hello all, Let me start by saying that although I have been working with PLCs for 20+ years I am very (as in brand) new to the Siemens world (my wheelhouse is AB). That being said I have a Siemens S7-1500 (1511 specifically) CPU with a couple of SICK multi-turn Profi-Net encoders (AFM60A-S4NB018x12) that I need to talk to. - I am using TIA v13 with all of the updates. - I have the GSD file from SICK for the encoder. - I have no clue what I am doing - I can see the encoder values update in the watch table as I move the encoder. All fine and dandy so far... Here's where the white flag is going up.... - I am of the belief that there are existing function blocks out there 'somewhere' that can read and write to the base parameters. I have contacted our local rep who deferred me to SICK. I have emailed and left messages with them and have not gotten a return anything thus far. Here's our application... We are attaching each encoder to its own rotary gear mechanism. The rotary will need to turn in the CW direction approximately 400 degrees then return to its start point by rotating in the CCW direction by the same amount. If/When production/maintenance needs to 'rehome' the assembly, the expectation is that they 'pin' the drive in a known location then a bit would be set within the CPU that would assign a specific value to the encoder's actual position. In the SICK manual (8015078/YIX6/2015-01-16) on page 31 (section 3.6.3) there is reference to Preset control. This is what I believe we need to perform the aforementioned function. Does anyone have any examples that they could share on how to read/write to these encoders by use of a Function Block or other? Relatively desperate for help at this point. Can post test code if need be. Thank you in advance, TLAF
