Status of aX Profibus Master
Before aX Profibus Master configuration is
possible, the aX Profibus channel must be active
(green in the aX Server window).

• The aX Profibus status popup displays
• the protocol name of your aX Profibus connection
• the status string (e.g. In Ring)
• the running counter of your aX Profibus
  connection
• the number of active devices
• the sum of input data
• the sum of output data

Display aX Profibus Parameters
For a detailed description of the aX Profibus
parameters refer to the docu-mentation of your
MIO_card.

• Right mouse click the Parameter button in the aX
  Profibus status popup to get the popup with the
  aX Profibus settings.

aX Profibus Parameter Description

• Address
• the master address in automationX can be 1 or 2.
• Default value 1
• Slot Time
• the maximum time a master station on this
  Profibus must wait for a transaction response.
  The Slot time is the maximum time the initiator
  waits for the complete receipt of the first frame
  character of the immediate acknowledgment or
  response, after transmitting the last bit of an
  action frame.
• Default value 200 Tbit
• tsdr_min the minimum time a slave must wait
  before it may respond.
• Default value 60 TBit (in case of the
  microprocessor 8051 --gt normal
  value 11 TBit )

aX Profibus Parameter Description

• tsdr_maxthe maximum time after which a slave
  must respond.If you use the automationX Profibus
  PCI or ISA card you can use up to 32 Profibus
  Slaves. The problem is, if you use more than 32
  Profibus Slaves the Profibus needs an tsdr_max
  lower than 500 TBit, but you need the more than
  350 TBit for the Master Master communication.
  For more than 32 Profibus Slaves you can set your
  tsdr_max in the range from 350 Tbit to 500 TBit.
• Default value 500 TBit (in case of the
  microprocessor 8051 --gt normal value 100 TBit
  )
• Ttr Target Rotation Timethe anticipated time
  for one token round on this Profibus, including
  allowances for high and low priority
  transactions, errors and GAP maintenance.
• Default value 60000 TBit
• Tset setup time
• the time between an event and the necessary
  reaction.
• Default value 1

aX Profibus Parameter Description

• Baud Rate the available baud rates of the MIO
  PCI Profibus card are 1500 kBit/sec, 500
  kBit/sec, 187,5 kBit/sec,
• 93.75 kBit/sec, 19.2 kBit/sec and 9.6 kBit/sec.
• gap range of station addresses from this
  station to its successor in the local token ring,
  excluding stations above hsa???.
• Default value 1
• has highest station address of masters in bus
  system
• Default value 2
• Max value 127
• Min value 1

Load and Save aX Profibus Master Parameters
When using long wires or a connection to another
aX Profibus Master, change the parameter settings.

• Load or save your aX Profibus settings using the
  buttons
• Load Prm and Save Prm.
• Choose the path and the file name of this file
  from the file selection box evoked by a mouse
  click on the field filename.

Reset the aX Profibus Master
After pressing the Reset button, the data
transfer to the devices is stopped.

• After changing one of the aX Profibus parameters,
  the button Reset --gt Set new PB Parameter will
  start to flash red.
• Press this button to reset your aX Profibus
  communication and to activate the new parameters.

Click with the right mouse button
10
Redundancy Channel
You need the redun-dancy channel to establish a
redundant automationX system.

• The status popup of the Redundancy card is
  similar to the popup of a aX Profibus channel.
• The aX Profibus settings of the redundancy are
  hard coded and cannot be changed.
• To reset the redundancy channel, use the Reset
  card button
