Hi My Problem solved. Now i can real time position values without any error in real time. Thank you verymuch    

Thank you all for reply. Tomorrow I will introduce this instructions and check. 

I am using a Omron NX102-9000 PLC programming through Sysmac studio software, I have a Data received in 2 words Hex 4453 7FE0. i need to convert this to Float format and result supposed to be 845.998 but when i combine and convert it to real it give result 1146322944.Need help to get correct format data.   // Shift High_Word to the upper 16 bits and combine with Low_Word Combined_Value := (SHL(TO_DWORD(Pos_XWord), 16)) OR TO_DWORD(Pos_XWord2); // Convert the combined DWORD to a REAL (float) Float_Value1:= DWORD_TO_REAL(Combined_Value);

Check your serial port programming cable.is it ok or not.Detection of Serial converter won't help to connect.Check other part too.

I had same error.did Uninstaller and reinstall.Updated version but error not solved.finally found solution.Just update in Tool-options-Ladder Editor-Ladderdiagram_Diplay Format-Display Connection of Ladderdiagram to 21 contacts.Then it solved

Hi Wasan, Thanks for the reply. For knowledge purpose does we have any similar stepper drive in market which has inbuilt Pulse generator. What is the type of concern drive.    

In One of my machine we using one stepper drive thatCTA2H328M-MB model made by Centrust Motors China running without pulse input.Direction and  Enable input only connected. My problem is motor running in low speed since drive is 2.89 Amps and motor is 4.2 Amps so its not supporting.I want change drive capacity but i couldn't found a drive with same concept.I couldn't able to reach the chinese vendor.I have tried many drives which is in my stock all are enable input used for enable/Disable the drive.I am bit confuced. http://www.centrust-motor.com/?c=msg&id=2337 Kindly help what type of drive is this? Which model will suitable for my requirement?  

@WasanKindly help to communicate

Dear Wasan, DVP ES2 wont support Modbus. Kindly help to communicate through RS 485.  

Hi Friends, In My new project I have used two Delta PLC'S (DVP-60ES2 and DVP 14SS2) I want to communicate both through RS 485 Communication protocol.We have  tried communication trough manual help.But Master Slave device not communicating.We have checked for any error code in D1130 but it always showning "K0" value.here with I have attached screen shots and complete program for yours kind reference.Kindly help and guide us to communicate.   Master.pdf RS485 master trail 1.dvp Rs485 trail 1 slave.dvp Slave.pdf

Der wasan, I tried to used this command but when I execute PLC going to error mode. Can somebody help me with a model program.     

Dear Friends, I am doing a pick and place project using stepper motor.programmed movement by PLS2 command and motion are running fine.I want to program origin for the stepper axis.Please help. i don't know how to origin with a home sensor input.I am using CP1E PLC and stepper driver DM860.

Posted 22 July · Report post Dear Friends,       I want to set my servo controller overload setting as per my machine load requirement since all my servo installed in my machine over travelling and hitting trying to run continuously which is resulting servo failures ,repeated timing belt cut issues.Kindly help me resolve this issue.since i am not familiar with servo controllers.Model used A5 II minas servo MADKT 1507 and contol mode in position control setting.
