WI-GTWY-9-xxx Wireless Gateway V1.18
Adding I/O to a Slave
The possible I/O combinations for a given slave may be fixed or configurable (i.e. modular)
depending on the GSD file for the device. When the I/O configuration is fixed, the fixed I/O are
always defined whenever the device is added to the network. However, for modular devices, the
I/O configuration must be assigned manually.
The GSD file for a modular slave will define a maximum number of I/O slots – each of which
may be configured with an I/O module. The available I/O module's for a particular slave can be
viewed by expanding the slave node in the Profibus DP Treeview. To add an I/O module to a
slave, first ensure the required slave is selected in the busview, then drag the required I/O module
into a spare slot of the slave listview.
When an I/O module is added to a slave, configuration software will automatically assign that
I/O to the next available space in the fieldbus interface. The input and output addresses that are
assigned here will correspond to the locations that must be transferred via fieldbus mappings in
order to make the I/O available to the radio network. The input and/or output address assigned by
software for a given I/O module can be altered by double clicking on that I/O module entry in the
slave listview (see above).
The start address in the fieldbus interface for the inputs or outputs can be altered in the
corresponding Start field as shown above. Since the WI-GTWY-9-xxx provides for up to 2048
bytes of inputs and 2048 bytes of outputs, the possible range for inputs or outputs is 0 – 2047.
