Man Roland 300 error SPS-BUS

I have the same problem with SPS - BUS on Man Roland 305+L (1999)
Gives errors with the code:
1) 0910004 Error reading control data.
2) 0901000 No data transfer
3) 0910104 Error transferring data.
4) 1211200 UWR (Control Processor) SPS BUS disconnected
5) 1217600 UWR (Control Computer) Station 1; Input data contains an error
6) HA (Main Drive) Missing phases in the network.
The machine stops at full speed. This error does not appear very often (1-2 times in a couple of months)

 

Most likely a processor board in delivery.

 

I need to replace the CPU board? Do you have its part number?

 

There are 4 different numbers in time. If you had written down the serial number of the machine, I would have told you the number on the board.
Shoot the SPS in the delivery. I'll show you.
Where are you from?

 

Hello friend, here is some information about my machine.
Type: R305 NL 5/0 1/4
Nr: 28203B Baujahr: 1999
I am from Russia myself.
