Declaration of the Profibus interface:
Manufacturers tag 0x3218 (UNIGATE IC-Profibus der Firma Deutschmann Automation
GmbH)
ASCIC-Type VPC3+B
Sync- und Freeze- Mode - is supported
(Sync- command: all outputs of addressed slaves frozen
Freeze- command: freeze all inputs of addressed slaves)
Cycle time Maximum duration until response of a request telegram, depending on bus
transfer rate:
9,6kBit/s – 500kBit/s → 15 Bit times
1500kBit/s → 20 Bit times
3000kBit/s → 35 Bit times
6000kBit/s → 50 Bit times
12000kBit/s → 95 Bit times
Diagnostic The Profibus module creates an external diagnosis when a fault is detected.
The diagnostic information of the DP slave consists of standard data( 6
Bytes) and a user specific diagnostic number (2 Bytes):
Octet 1:
Bit 0 = Diag.station does not exist (set by master)
Bit 1 = Diag.station not_ready: slave is not ready for data transfer
Bit 2 = Diag.cfg_fault: configuration files do not correspond
Bit 3 = Diag.ext_diag: slave has external diagnostic data
Bit 4 = Diag.not supported: requested function not supported by slave
Bit 5 = Diag.invalid_slave_response (perm. sets slave to 0)
Bit 6 = Diag.prm_fault: incorrect set up (ID number etc.)
Bit 7 = Diag.master_lock (set by master): slave configured by other master
Octet 2:
Bit 0 = Diag.prm_req: slave must be reconfigured
Bit 1 = Diag.stat_diag: statistical diagnosis (Byte Diag-Bits)
Bit 2 = 1
Bit 3 = Diag.wd_on: polling supervision activated
Bit 4 = Diag.freeze_mode: freeze command received
Bit 5 = Diag.sync_mode: Sync command received
Bit 6 = reserved
Bit 7 = Diag.deactivated (set by master)
Octet 3:
Bit 0 – Bit 6 = reserved
Bit 7 = Diag.ext_overflow
Octet 4:
Diag.master_add: master address after configuratin (FF without configuration)
Octet 5: ID number High byte
Octet 6: ID number Low byte
Octet 7: external diagnosis: header length
Octet 8: internal UNIGATE- fault code
