End field device output module accepts 0-27648 as range to give output 4-20mA . Can you guide how this range can be scaled by using SCL function in PLC program?

Hello, Thanks for reply. Yes Baud rate is changed - becuase the UPS modbus RTU Slave device works well with Modscan Master Simulator tool over 9600 baud & with same setup the slave device is not communicating with My device ( Modbus RTU Master) I will check for cable shielding etc & use proper...

Yes, correct. We are going to check these damaged devices . Thanks for your kind reply

I was just going through all replies as my problem is not yet solved. Yes the serial connecting cable is screen connected at both ends to metal part of connector. Do you want us to remove this schielding ?

thanks all of you for this information. The customer has done one thing . Now our protocol converetr is mounted slightly above to the panel . i.e the din -rail is lifted up with help of some plastic bush. I have attached photo for your reference. you will see yellow marked bush . which...

Sorry to disturb again. I have again one query -- you mentioned above as below - You didn’t answer the question about grounding the shield drain wire at only ONE end. If it’s grounded at both ends that can cause circulating currents in the shield which will probably make any induced voltage...

ok thanks for your help.

1). Did you use twisted, shielded wire/cable for the interconnecting signal transmission—AND did you ground the shield drain wire only at ONE END? ---the serial RS232 communication cable is NOT twisted pair . It is normal cable with schielded. shield of the cable is soldered to DB9 connector...
