6.9.2 Diagnostics with channel referred information
Parameter: „Extended Diagnostic“ Enable
This diagnosis consists of four parts:
1. Six bytes of standard diagnostics
2. 35 bytes Device-related diagnosis
3. 2-3 bytes of identification-referred diagnosis (Number depends on number of attached Extension IO mod-
ules <= 7 = 2 bytes, >7 = 3 bytes)
4. n bytes channel-referred diagnosis (The channel-referred diagnosis is as largely as the number of arising
errors times three bytes)
Standard diagnostics
Byte 0, station status 1
Bit 0 station_non_exist 1 = station can not be reached; always "0"
Bit 1 station_not_ready 1 = station is not ready for data exchange
Bit 2 cfg_fault 1 = configuration error with the master
Bit 3 ext_diag 1 = extended diagnostics data is available
Bit 4 not_supported 1 = a requested function is not supported
Bit 5 invalid_slave_response 1 = the slave response was not valid
Bit 6 prm_fault 1 = false or incomplete parameter data
Bit 7 master_lock 1 = parameters are from another master set - access is locked
Byte 1, station status 2
Bit 0 Prm_req 1 = parameter must be transmitted again
Bit 1 Stat_diag 1 = diagnostic data is present
Bit 2 “1” Slave always sets "1"
Bit 3 WD_ON 1 = The slave has activated the watchdog
Bit 4 freeze_mode 1 = The slave has received the "freeze" control command
Bit 5 sync_mode 1 = The slave has received the "sync" control command
Bit 6 reserved Slave always sets "0"
Bit 7 deactivated 1 = set from master, slave is inactive, slave always sets "0"
