Mapping Configuration Parameters
Destination
– Shows two standard choices as well as a radio IP and an Ethernet IP
address for each module in the project. The first choice is ‘Local Host’ which is the
standard name given to the address of the loopback network interface and basically
means the module you are currently configuring (itself). You will notice when this option
is selected the IP address will change to the localhost loopback address of 127.0.0.1.
The second choice is
‘IP address’ which will allow any IP address to be entered into the
configuration. This option is for advanced users only as the Remote Name & Address
location will not show up in the I/O list. Knowledge of the remote modules I/O location
and address is required for it to function correctly. Generally is only used when a
module that is not in the project is loaded or is being mapped to.
The remaining options in the Destination drop down list will show the Radio IP address
and the Ethernet IP address of all other WI-I/O 9-U2 modules in the project. When
Radio IP is selected this means the mapping will be sent over the radio network and is
the most common form of destination selection. When Ethernet is selected this means
the mapping will be sent to the Ethernet address port of the WI-I/O 9-U2. You must
ensure that the Ethernet port is enabled on the Ethernet tab in the project tree for the
sending and receiving WI-I/O 9-U2 modules and that the IP addresses of the sending
WI-I/O 9-U2 and Receiving WI-I/O 9-U2 are able to communicate to each other.
Name - Each Mapping can be given a name for reference when viewing in the
mappings screen.
IO Table - The main configuration is done in the IO table by selecting I/O and mapping
it to an output. You can click in the
‘Local Name’ cell for a drop down list of all of the
available I/O or click in the ‘Local Address’ cell for a tabbed I/O selection screen that will
allow you to select an I/O point (Input) that you wish to map, next click in either the
‘Remote Name’ cell for a drop down list or the ‘Remote Address’ cell for an I/O selector
screen showing destination I/O locations. Note: a Destination address must be
selected before a ‘Remote Name’ or ‘Remote Address’ can be selected.
The ‘I/O Count’ field selection allows the addition of more I/O points to the mapping. If
using a Write and Read mapping it will automatically select consecutive registers that
