@WasanKindly help to communicate

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

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.

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.

Thanks Jay.Problem solved and machine working fine.

I am using CJ2M PLC.I want switch on a output for certain time by a timer and holding bit if interlocks satisfied.If interlock not OK timer has to hold the time and output should be off. if again interlocks OK again output has to ON upto balance time completion and has to give timer done output for reset holding bit.please suggest.

Thank you Jay i will try and reply.Please reply about can we use MTIM for this requirement I have tried MTIM getting reset and again running cyclical.

Somebody please help me

We using Omron R88-GP series servo in one of our machine.we couldn't identify this series in cx drive or omron catalogue.We Need servo parameter software to be used for R88D-GP01H-Z.Please Help.

Here there is no alpha numberic for DI/DO you have to adresss inputs for example 0.00,0.01,0.02 ,outputs 10.00,10.01,10.02
