Sync-Mode
Freeze-Mode
Is supported.
Sync command: Freeze all outputs of addressed Slaves.
Freeze command: Freeze all inputs of addressed Slaves.
Cycle time Maximum response time to a request telegram depending on the Bus transmission rate.
9.6 … 500 kBit/s: 15 Bit times
1500 kBit/s: 20 Bit times
3000 kBit/s: 35 Bit times
6000 kBit/s: 50 Bit times
12000 kBit/s: 95 Bit times
Diagnostic The Profibus module generates an external diagnostic if it detects an internal fault. The dia-
gnostic from the DP Slave contains standard diagnostic information (6 Bytes).
Octet 1:
Bit 0 = Diag.station does not exist (set by Master)
Bit 1: Diag.station not_ready: Slave is not available for data exchange
Bit 2: Diag.cfg_Fault: Conflicting configuration data
Bit 3: Diag.ext_diag: Slave has external diagnostic data
Bit 4: Diag.not supported: Requested function is not supported in the Slave
Bit 5: Diag.invalid_slave_response (set to 0 by Slave)
Bit 6: Diag.prm_fault: Incorrect parameter settings (ID number, etc.)
Bit 7: Diag.master_lock, Slave is configured by another Master (set by master)
Octet 2:
Bit 0: Diag.Prm_req: Slave must be reconfigured
Bit 1: Diag.Stat_diag: Static diagnostic (Byte Diag–Bits)
Bit 2: fixed to 1
Bit 3: Diag.WD_ON: Response monitoring activated
Bit 4: Diag.freeze_mode: Freeze command received
Bit 5: Sync_mode: Sync command received
Bit 6: reserved
Bit 7: Diag.deactivated (set by master))
Octet 3:
Bit 0 … 6: reserved
Bit 7: Diag.ext_overflow
Octet 4:
Diag master_add, master address following configuration (FF without configuration)
Octet 5:
ID number Highbyte
Octet 6:
ID number Lowbyte
Parameters Only cyclic communication supported
Automatic Baud rate
recognition
