Master Settings
Set the master parameters (transmission speed, FDL address, or other items of the DP-Master).
[PROFIBUS Network]
Right-click the master module

Description
Setting range
Name
Sets the master module name.
1 to 16 alphanumeric
characters
Baudrate
Sets the transmission speed of the PROFIBUS-DP network.
All the DP-Slaves should support the transmission speed to be set.
Turn off the power of the DP-Slave when changing the transmission speed. When the power is turned
off, the DP-Slave synchronize to the new transmission speed.
9.6kbps to 12Mbps
(Default: 1.5Mbps)
[Bus Parameters] button
Sets the bus parameters.
For the bus parameters, refer to the following.
Page 85 Bus Parameter Settings
FDL address
Sets the FDL address.
0 to 125
(Default: 0)
Intelligent Module No.
Displays the mounting position of this module.
Error action flag/Goto
'Clear' State
Checks this box to send the clear request to all the DP-Slaves from the DP-Master.
When a communication error has occurred even on one DP-Slave, the clear request is sent to all the
DP-Slaves.
• Not checked: Not send the clear request to all the DP-Slaves.
• Checked: Sends The clear request to all the DP-Slaves.
• Checked
• Not checked
(Default: Not checked)
Min. slave
interval
Sets the minimum time required from the slave polling cycle to the next slave polling cycle. (Unit:
100
μ
s)
This setting value is effective against all the DP-Slaves connected.
1 to 65535
Calculate
time
Checks this box to automatically set "Min. slave interval" based on the predicted bus cycle time.
• Checked
• Not checked
(Default: Not checked)
Use 'Min. slave interval'
for 'Target Token
Rotation Time (T_tr)'
Checks this box to automatically set "Min. slave interval" to the value set for "Target Rot. Time (T_tr)" of
the bus parameter.
When multiple DP-Masters exist in the PROFIBUS-DP network, checking this box is not necessary.
T_tr is set to the sum of "Min. slave interval" of all the DP-Masters.
• Checked
• Not checked
(Default: Checked)
Polling timeout
Sets the maximum time required for the requester to receive the response during communications
between DP-Masters. (Unit: 1 ms)
1 to 65535
(Default: 50)
Slave
watchdog
Check this box to collectively set the watchdog timer for all the DP-Slaves.
• Checked
• Not checked
(Default: Checked)
Calculate
time
• Checked: Sets automatically an optimal value for "Slave watchdog".
• Not checked: Sets an any value for "Slave watchdog". (Unit: 10ms, default: 3)
The automatically set value is five times of estimated bus cycle time or "Min.slave interval".
• Checked
• Not checked (1 to
65025)
(Default: Checked)
