    welcome back Chris, i am pleased to see that MrPLC is under your management....

    i did not...i tried but my phone connection was rather spotty and searches were slow, and the plant did not have guest WiFi so i was on my own. i tried all i could think of to no avail. and changing Locale was the only thing remaining that i could think off (at least one that was easy and quick to try). i have seen similar issues reported for other products (users from different countries running into issue with specific software, like WorkVisual etc.). another clue was seeing comments in the freshly uploaded PLC code. Machine was built in China but the comments did not look like Chinese characters at all although there are several Chines fonts on every Windows machine (SimSun, SimHei....). but the PLC texts and comments were rendered in "garbage" ASCII characters one normally sees when looking at binary files in a text editor. so after dozens of failed attempts i tried this and - voila. it worked instantly.

    Was repairing piece of equipment and first time experiencing NB product. the NB Designer was not part of Omron suite so had to be downloaded separately. It is a free download. USB driver was included. Uploading project from HMI was straight forward, default password worked: 888888 The problem was trying to decompile uploaded file. It kept asking for another password, and then failing. Messages suggested that file was corrupt or password was wrong or wrong length (since it did not work, i did try guessing...). Message was: PKG file error, possible destroyed Turns out file and password were fine. The only thing needed was to change Locale of the computer on which NB Designer was running to a Chinese Traditional (Taiwan) and reboot. After this decompilation was a snap. Maybe this helps someone else too. Cheers...

    Any modern Ethernet switches will automatically only forward traffic to right ports. In fact this is an issue of one wants to listen to traffic between other nodes. And this is what managed switches are for. one can create own rules to forward traffic to specific port (for listening/monitoring) or block off unwanted traffic or force certain behavior such as forcing baud rate, enabling/disabling auto negotiation etc,

    K30GL is just a crimper. it does not cut or strip wire, does not have ferrule magazine...

    this would be much easier to answer if the exact product type was mentioned.

    internet search revealed posts that suggest running software as different user (not admin), check front properties (must not have protected attribute). nothing worked.

    hello everyone, Got a PLC/HMI project from machine vendor. The problem is that HMI does not compile. Both fonts are present of course but message suggest error stripping the font.... Sometimes there is additional warning about SimSun but that is just a warning...

    i am not using those exact product but... i have worked with EtherCat many times and connected multiples of same nodes without issue. each physical node gets its own instance in the controller. you do not access one node to get the values to/from the other, so it does not matter that PDOs are named the same way - they are in a different instance/node. in terms of troubleshooting first thing is always to see how they are all connected, and is the network topology correct. lets put it this way: if the hardware side is not setup correctly, there is no hope of stumbling on correct settings in the software. in EtherCat network, nodes are daisy chained. branches are possible but there are limitations and this requires hardware that supports this. so once the hardware side is verified, one can deal with the software. how did you configure it in your controller? did you scan the network or manually populate it? are you sure that topology in software matches what you have done in hardware?

    you can replace it with many products. the question is why... are you running out of I/O or need something that you do not find in that product? alternatives are likely going to cost more not to mention time to create documentation, code and have it all approved.

    using speed control allow you to control the speed but it will not get you precision when it comes to position. for precise position cuts you need position feedback. doe your axis have an encoder?

    well, time is running out, got to make it work... drive memory is organized in menu/parameter fashion. until i have time to investigate closer, i will be using few unassigned menu locations. this is less than ideal since they are scattered ... would prefer single (or two) blocks of memory without tiptoeing around used ones. oh well...

    hello everyone, I am able to connect to servo using driver device/server "Control Techniques SI-Ethernet Modbus TCP". this accesses servo by specifying memory locations in form of menu entry and parameter number. But i need to exchange more than that. drive has built in PLC and i did not find out what device driver or settings would allow that. any ideas?

    did you try manually setting the outputs on? are you sure there is nothing clearing them? did wiring change at all? problem started after program download?
  15. panic mode
    exactly

    those are just shared properties. clicking on radio button 'All properties' should show longer list...

    check the wiring including terminations. also, check the baud rate. what is the expected role of this unit? it can be bus master/slave or both. bus must have a master("scanner") and one or more slaves ("devices"). some slaves can autodetect baud rate. this is convenient when it works but unfortunately sometimes they also get it wrong and that is a bad situation to be in as there is next to nothing one can do to solve it. unlike other bus types, DeviceNet uses additional pair of conductors that need to be powered by 24VDC. somehow this is also a pretty common issue as many fail to realize that they are responsible to bring this power to the bus. some fail to ground the bus shield or they ground it in more than one place (this allows for ground loops and interference) or they strip way too much of the shield so that shielding is ineffective. if your CJ1W-DRM21 is working as a master (scanner), you need to load correct configuration into it ("scan list" is usually created in PC software after importing suitable EDS files for each of the slaves)

    using safety PLC does not mean that end result is safe. it only means that it is capable of applications requiring safety - if used correctly. ultimately it is still up to programmer to configure and program it correctly. without software one cannot check your program. you may considering printing or exporting it into a PDF form so anyone can offer feedback. even for EStops, it is not enough to put them in series with something. safety standards have various criteria that need to be met and this is determined through evaluation process (aka Risk Assesment).

    coil instruction is used to assign both true and false values: variable := expression; or in your case start := (i_SW1 or start) AND NOT I_Off; I_Off := start AND i_sensor4; ...etc.

    in DotNet one could use PathGeometry and ArcSegment. to go beyond 180deg property IsLArgeArc would need to be set to true btw, have not seen it in years but it looks like required level of customization for something like this may be possible with factorytalk view studio SE as well. what properties are exposed for objects like arc or wedge?

    VisualStudio.... initially it would be the 3rd party driver/ActiveX/SDK as this is the fastest way to get results. but that is something we rarely do today. just about all are done internally, either from scratch or by using open source or SDK if and when vendor offer it. many devices use simple protocols that are easy to reverse engineer. the usual application would be some GUI software that has many simultaneous connections to different devices (PLCs, robots, other PCs, CNCs, RFIDs etc.). and if don't want to waste the time on something new (fieldbus etc), we just add the option (driver or hardware) to one of the system components (PLC or robot) as we can already talk to those.

    well that is one of the reasons we went away from integrated solutions built around industrial HMIs and use industrial PCs with our own software. they are usually comfortable and learning curve is short but one has to live with limitations. for us it meant initially we had to develop more but - it is up to us what we do with it and that means everything is possible. no more limitations like screen size or resolution, number of displays, number of tags, type of controls available etc. when something is needed but not already there, we create it. once done it can be used many times and in any project.

    i am guessing you are trying to make a custom HMI object but i cannot figure out why would border need to change and why would that need to depend on assigned tag instead of tag value. one should be able to accomplish by scaling (height/width). what software you are using?

    number of pulses tells how far to move... rate at which pulses are sent controls the speed. so maximum frequency of the PTO is one of limiting factors. small PLCs often have PTO that only get to few kHz, some may go to 100kHzor 200kH, dedicated modules for larger PLCs are definitely more capable (MHz). by parametrizing drive one can accomplish certain scaling so that for example axis can reach higher speed even when driven by slow PTO. but don't be fooled - this is a tradeoff... you may gain at one end (speed) but you loose at another (resolution). so one need to read the manual, do the math and set parameters correctly to get needed performance. but once you reach point where PTO cannot handle it, it is time to upgrade to more capable PLC.

    looks like that output is fried...
