Thankyou very much appreciate your help Best Regards, Vib

Hi, i have alpha 2 plc, which i have done programming using Visula logic, turning some outputs on / off using inbuilt timer function block but modifying inbuilt timer function block using small display is bit hard i am planning to use hmi got10 series, is it possible to edit the inbuilt time function of alpha2, through HMI if some one has a sample program , please share it   

Thanks, i will try that, best regards,   Vib

Thanks goran,   i will change the logic using dedicated commands,   i have used that incremental concept and resetting in the logic    For me to know absolute position of the motor in reference to zero, i have to link the registers in sequence   i think there is a logic of first in last out, might help me to link the registers in sequence   thanks for your help   best regards   vib

Hi please find the code attached i have 2 pole motor, which runs approximately at 3000 rpm, and encoder is 2000ppr Frequency is approx 100 khz, Counting is not a problem, its just holding the values 32 bit register can hold 2 billion bits, and at 100khz , my data register will be filled in 2000 sec, i need it to operate for much longer time than that so my quest is if it reaches lets say 1 billion bits, it automatically attaches it to adjacent register Explaining it in simple ways would be, i have created dataflow as a water flow analogy i will try with index registers, since its used for positioning, i will still be required to add the values, and then start decrementing them in reverse order i am still trying to get my head around Last in first out command and shifting registers, may be that can work  thanks  Best Regards, Vib Encodercontrol.pdf Encodercontrol1.pdf

Hi, data registers are getting full, because of extremely high speed pulsing is there any way , if the data value in register goes above the capacity of 32 bit register, it automatically attaches itself to next set of data registers so lets say if data was written in D10,D11 Upon reaching the limit, it goes to D10, D11, D12, D13 please share if there is an alternate way to do this

Hi Wasan   thanks for the reply    i tried 2 different modules   Module 1:- FX3U-4AD-ADP, It is connected on left hand side of plc   This Analog module is connected to expansion board bolted to mitsubishi plc   Expansion board:- FX3U-CNV-BD I am using a signal generator to generate 4-20mA signal Wiring  Connecting +Ve to V+ Bridging link between V+ and I+ Connecting Comm to -Ve   program attached   Second method was using FX2N 2AD, which connects on right hand side of the fx3u plc via ribbon cable,  Please find screen shots of plc attached to word file as attachment Hope to hear soon from you Best Regards,   Vib     MITSUBISHIPLCANALOGPROGRAMMING.docx MITSUBISHIPLCANALOGPROGRAMMING.docx

PLC:- FX3u-48MR Analog card:- Fx2n 2AD Signal source:- 4-20mA Signal generator Tried rd3A Command Tried TO & FROM Command PLC doesnot read the signal, yet no error, wired as per manual... Please suggest if anyone has answer to this problem?

Hi  i purchased got1000 online from ebay   i want to start programming it, but its password protected   How can i factory reset and start from scratch
