How do you detect the individual Slave failure?
To detect the slave failure, you may use the command error list. Each command returns an error code once it is executed. If a command returns a value different of 0, this means that there was a problem during the command execution. The command error list can be found in the read data zone at the address you specified in mcm.port1.cmderrptr.
