3 Variables <strong>11</strong>.033.<strong>11</strong> Diagnostic datadpSlaveStateCommThe slave is active on the bus once the drive assigned tothe slave has successfully logged on to the bus.True: Slave on busFalse: Slave not on bus- 0 0 1 UWordMulti-line: nodpSlaveCfgNumSlavesdpSlaveStateIncCntThe incarnation counter of the slave.It is increased by one everytime when the slave is accepted by the bus. If the slave falls out of the bus, this counter isnot changed.After the first time in the bus (i.e. the first operating status of the slave), the value is 1.If there is an area overflow, the counter starts again at 0.This functions only with slaves that have at least one allocated NC axis. With other slaves (pure I/O slaves, or axescontrolled by the PLC), this value remains at 0.From 0 (start value after new start) up to max 2147483647 (2^31-1).- 0 0 2147483647 UDoublewordMulti-line: nodpSlaveCfgNumSlavesdpSlaveStateSyncThe drive linked to this slave is operating in cyclic mode.Slaves without a drive are defined as "non-cyclical".True: CyclicalFalse: Non-cyclical- 0 0 1 UWordMulti-line: nodpSlaveCfgNumSlavesdpSlotCfgAssignAxisThis data supplies the axis indices of the drive, encoder 1 and encoder 2for access in the Axis-Assign-Table.The 32-bit value consists of 4 bytes with the following meaning:Byte0(bits 0-7) = axis index of axisByte1(bits 8-15) = axis index, encoder 1Byte2(bits 16-23)= axis index, encoder 2Byte3(bits 24-31)= provided for future extensions.A byte with the value 0xFF indicates that no axis indexis defined for the relevant slot.- 255 0 32 UDoublewordMulti-line: nodpSlotCfgNumSlotsdpSlotCfgAssignBusBus number assigned to this slotSince only one bus is currently supported by Profibus DP,there is only one bus to which all slots are assigned.- 0 0 1 UDoublewordMulti-line: nodpSlotCfgNumSlotsdpSlotCfgAssignClientThis data supplies the clientIndex for accessing theClient Assign table.0=no assignment possible (this applies to diagnostic and PKW slots)>0 assignment exists- 0 0 2 UDoublewordMulti-line: nodpSlotCfgNumSlots© Siemens AG, <strong>2003</strong>.
