3.4.1 Data in Octet 1: Station Status 1
Fig. 19 shows the coding of octet Station Status 1 in accordance with DIN E 19245 Part 3. Station
status 1 comprises information which is either generated by the master or by the DP slave itself.
The bits which are controlled by the master are generally set to zero by the DP slave. In the follow-
ing the individual status bits will be discussed in greater detail.

Fig. 19: Coding of the octet Station Status 1 to DIN E 19245 Part 3
The individual bits have the following meaning in accordance with DIN E 19245 Part 3:
Bit 7: Diag.Master_Lock
The drive inverter as DP slave sets this bit permanently at zero. This bit is set by the DP master
(class 1) if the address in octet 4 is not equal FFhex and not equal to its own address. It indica-
tes that the MOVIDRIVE
®
drive inverter was parameterized by a different master with the
DDLM Set_Prm service.
Bit 6: Diag.Prm_Fault
This bit is set by the MOVIDRIVE
®
drive inverter as DP slave if the last parameter message
(DDLM_Set_Prm) was incorrect, e.g. incorrect length, incorrect Ident Number, etc.
Bit 5: Diag.Invalid_Slave_Response
The drive inverter as DP slave sets this bit permanently at zero. This bit is set by the DP master
if an invalid response was received from the MOVIDRIVE
®
drive inverter.
Bit 4: Diag.Not_Supported
This bit is set by the MOVIDRIVE
®
drive inverter as DP slave if a function was requested which
is not supported by the drive inverter.
Bit 3: Diag.Ext_Diag
This bit is set by the MOVIDRIVE
®
drive inverter as DP slave. It indicates that a diagnostic
entry has been made in the unit-related diagnosis section (see octet 8: Unit-related Diagnosis).
Bit 2: Diag.Cfg_Fault
This bit is set by the MOVIDRIVE
®
drive inverter as DP slave if the configuration data last
received by the master do not correspond to the configuration data supported by the MOVI-
DRIVE
®
drive inverter.
