Parameter Tab
The Parameter tab lists all settings to be made for the Parameter message. The Parameter tab is
shown below (Example shown is the Parameter tab for an OMRON CJ1W-PRT21 PROFIBUS DP
Slave Unit).
 Common Parameters
The PROFIBUS DP parameter message contains a number of settings for the slave device. It is
transmitted to the slave device before the I/O configuration message. In most cases a slave device
requires a block of Common Parameter settings, i.e. settings which apply to the whole device.
 Module Parameters
However, there are also more sophisticated (modular) devices which require parameter settings per
I/O module selected. The specific parameters blocks can be selected from the drop-down list at the
top of the Parameter tab. In the figure above, the Common parameters are shown. This particular
device does not support module parameters, so the parameters shown are the only ones shown.
The Parameter list consist of a left column containing the name of the parameter and a right column
containing the settings options. In order to change the parameter setting, double-click the row with
the left mouse button. Depending on the type of parameter and the selection options, either the field
can be edited directly or a drop-down list with options will appear.
Note The parameter settings must be performed carefully. In general, the slave device will reject
the parameter message if it contains any faulty parameter. Consequently, the slave device
will not reach I/O data exchange with the PROFIBUS Master.
The parameter values are by default displayed in hexadecimal format. By checking the check box at
the bottom the values are converted to decimal values.
