Synchonization of UCVE in MarkVI

We are using Mark VI Speedtronic control system. When booting the channel S, we have channel S fault. We do application code download, but it fails due to SDI disconnect. We boot the other channel, and now we lost communication data with all channels, getting only zero value.

Please show me what wrong with this.
Best regards!
 
It is better to reboot all channels together.
The SDI disconnect we always think that has a problem at the flash memory. You can do as below:

12.2.1 Establish serial connection between HMI or PC and the COM1 port on the UCVx board using a Micro-D connector
12.2.2 Establish a HyperTerminal session
12.2.3 Reboot the controller and wait for a message ¡°Press RETURN key within 2 SECONDS to ABORT uc2k startup¡±
12.2.4 Press the Return or Enter key within 2 seconds to stop the UCVx from loading the Application code.
12.2.5 Go into the UCVx and delete the UC2K.sym and UC2K.cfg files located in the apps directory as follows:
12.2.5.1 Login to the UCVx:
12.2.5.1.1 Login: root
12.2.5.1.2 Password: ge
12.2.5.1.3 You will be inserted in the \bin subdirectory.
12.2.5.1.4 Type ¡°cd ..¡± (change directory space .., to move up one directory level)

12.2.5.1.5 Type ¡°Cd apps¡±
12.2.5.1.6 Type ¡°LS¡± to list files in a directory
12.2.5.1.7 This list will show the UC2K.sym and UC2K.cfg files.
12.2.5.1.8 Type ¡°rm uc2k.*¡± to delete these files.
12.2.6 You can down load in the proper sequence, and then reboot.
12.2.7 This problem can be avoided if the user downloads runtime first, before downloading the application code.
