Thanks Everyone The program i am writing requires 3 individual mini sequences and went something like : 1. DMOV the value of the counter C235 into D0 Then sequence one: DMOV a K value into D1 and a K Value into D2 (I did not realise D1 would be affected by DMOV  into D0) Then a math instruction to compare the Value of D0 with D1 and again the Value of D0 with D2 to give two separate outputs. The problem was the value in D0 would never travel over 32767 (16 bit) and my value in D1 and D2 were larger. I have actually change the program to work with DCMP instructions, but i am interested to understand how to DMOV 32 bit data. Regards Paul

Thanks Andreas I have taken a look at the high speed processing instructions like you advised, unfortunately I would have to re-think the whole program if I were to use them. Is there any other way I can transfer the value of a HSC into a 32 bit memory, so I compare the values later in my program. Regards

Andreas I am using a FX3s PLC Regards

Andreas  Thanks for the help. I have tried to type this instruction (DHCMOV) into software (GX Works 2) but it does not recognise the instruction. I assume I use an application instruction. Thanks in advance

Thank you for the speedy response. I will try this and let you know the outcome. much appreciated regards

Please help. I am using a rotary encoder with high speed counter C235 in my program to monitor the position, and to pause the motor after a number of pulses from the encoder. I have used a DMOV instruction to transfer the value of C235 to D0, but when I am monitoring the value in D0, it never rises above 32767 (I assume 16Bits) and I need to pause the motor at value 75000. What am I doing wrong? Thanks in advance

 Have a problem I need help with please.. I am using an encoder 1024 ppt with C235 to count up.. I want to compare to D values but because they are 16 bit values I can only compare values up to 32767.. does the fx3s have any 32 bit internal bits    Thanks in advance
