AC 800F replaced a new PM-803F not work
There is a question for AC800F. The PM-803F of AC800F is not worked ,so i buy a new one replace it.But still i install the new PM-803F,and load the operating system, the equipment is also not work.There are two question: one is the LED light of SA 811F is in off state;the other is both of the LED light in FI 830F is off state.Please give me some help.
The question is in this Figure
Please check below
Is the controller firmware is updated from current running CBF machine?
Check the profibus communication module (FI830F) also updated from CBF, verify the versions of old running controller and new one.
Also share the some screen shot of CBF in commissioning mode & controller logs
So I'd try checking the Software versions on the controller's diagnostic page. It should look something like this:
BootLoader: 10.30 
Runtime System: 10.35
HW Selftest: F04.102.00
The bootloader and runtime system versions need to agree on both controllers.
If they don't, you'll probably need to figure out which Freelance version and roll-ups were used on the running controller.
Alternatively, connect the serial diagnostic cable to the replaced controller and observe the bootstrapping.
