Parameter Tab
Common Parameters
Module Parameters
Group 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).
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 required a block of Common Parame-
ter settings, i.e. settings which apply to the whole device.
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.
The Parameter list consist of a left column containing the name of the Param-
eter and a right column containing the settings options. In order to change the
parameter setting, double-click the row, with the left mouse button. Depend-
ing 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. Any faulty parameter in
the message and the slave device will in general reject the message and it will
not reach I/O data exchange with the 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.
In the Group tab the user can define to which group the slave device will
belong. This group definition is used to define multi-cast groups of slave
device to which a Global_Control message can be transmitted. The window is
shown below.
