I'm pretty new in Mitsubishi, so i must clear some doubts. I've been reading the manual but i don't get clearly how the analog outputs work. I already programmed the FROM and TO instructions that mention in the manual so the outputs get activated, but i don't understand which is the tag that will contain the information for each channel.
I only have to use one channel in voltage mode. I hope i explained myself clearly. Share this post Link to post Share on other sites. Prog software and language type? How does your program look so far screenshot?? Here i have a screenshot from the analog module's manual, and i wrote the same in my program. I did't test it in the PLC yet, but i would like to understand what exactly it is saying.
In that example the program sets Chanel 1,Chanel 2 as voltage mode, and Chanel 3,Chanel 4 as current mode. I only need to use Chanel 1 or Chanel 2 as voltage. I 'm using GX Developer v 8. OK, Rungs: 1. Reads 1 register from module 1, BFM 20 into D4 model code 2. Checks the bit0 M10 and bit10 M20 to control for any abnormal data. That means, for instance, that i can use register D1 to save the scaled analog value?
Channel 1 output is D0, not D1. He's using both channel 1 and channel 2, hence both D0 and D1. His original post said only using one channel of voltage output. Keep in mind that the FX1N only allows 2 extension modules on the right hand side. Edited 10 Dec by Leandro. That analog board already installed does NOT use D0 unless the program is coded that way. The actual number to adjust the analog output is written to D I've already programmed everything but the plc doesn't seem to recognize the Analog module.
Am i Missing some hardware configuration? Post your code. Are you getting an error code in the PLC? There is no setup required to connect the module other than plugging in the ribbon cable and the couple lines of code mentioned earlier. Here is the error in the picture. I'm copying 4 registers beggining in D5 , as voltage mode. But nothing happens. Curiosly the other Analog output used with 1DA module does work with D Sorry, i'm on mobile phone.
Make sure that the extension cables are connected propertly. I suspect you have them wrong. The example code from earlier all shows K1 as the first parameter, which would be the second attached extension module.
You said you only have one, so I would expect that first parameter should be K0 for you. Here is the code in the picture. The module's manual shows that code for basic programming.
Edited 30 Dec by Leandro. Your TO instructions first parameter K1 indicates module number 2 since the addressing is zero-based. Where is your module located on the right hand side of the PLC? First module? Second module? The module is the first and only one on the right side of the PLC, so as you explained, i should write "K0" instead of "K1" in the first parameter of TO instructions. I didn-t know that parameter meant "module number".
Thanks, i will try that way! Hello, I'm here again with a problem in the analog output scaling. What i need to do is to scale the output channel in order to command a Mitsubishi Motor Inverter from 0 to 50 Hz Frequency.
Everything is already connected and the manual of this module says that the analog output works from 0 to This is for a motocycle production line en Honda Factory. They work with Takt counting.
The Takt is the time that the line chain takes to run a certain distance, for instance: seconds per 2,5 metres of chain. What i need to know: which is the best way to scale the analog output? I must work in the interval , in order to get values from V in the analog output, and then finally get values from Hz in the Inverter. A certain value in the analog output must set a certain Takt Time.
This value is stored en D register. Then, what do i need to calculate so the analog output sets the desired time? If anyone has experience in scaling outputs, would be very welcome. Thanks very much! First you need to explain what the desired output will be for each time. So when you say seconds, how much analog do you need? After that it's simple math. Prev 1 2 Next Page 1 of 2.
