Hi, can u please help me? how to download program to PM554_TP. i have cable that Rs485 to USB. ist possible to use this cable?
first you need to be sure the cable(converter) had been configured in your PC OS
you can do that by check the Hradware manger in the control panel
from that you will know the Com address of your cable
in the coDesys you need to change the com adress to that arddress !
that to be done in the communincation parameters under online
After that you can download your application to the PLC by using the login button (after rebuild the program )
