Configuring the PROFIBUS DP network

Setting Parameters
The parameters are sent by the Master unit to the slave device prior to estab-
lishing I/O data exchange. The slave device will reject incorrect parameters
and not establish I/O data exchange, unless the parameters are changed.
In general there will be two types of parameters.
• Common Parameters
The PRT1-SCU11 defines one Common parameter, which applies to the
unit itself. This parameter - Fail Safe support - defines whether or not the
unit will accept empty output messages or messages containing all zeros
in case the PROFIBUS DP Master switches to Clear mode. Clear mode is
often the indication of a failure on the network.
• Module Parameters
Modular Parameters are parameters which are associated with the I/O
modules selected. In the case of the PRT1-SCU11 these parameters
define behaviour with respect to the devices attached to the PRT1-
SCU11. They are discussed in the next section.
Example
The Parameter tab of the PRT1-SCU11 is shown in the figure below. It lists
the parameters for the selected temperature controller the E5ZN-Extended 2
Channel 11WI/3WO. The parameter captions are listed in the left column and
the options can be set in the right column. In order to change settings, double-
click the required parameter row with the left mouse button. Depending on the
parameter type, either a drop-down list will become available for selection or a
value can be entered.
