DataSocket URLs for FieldPoint I/O Modules
The following is an example of a DataSocket URL that points to a specific
channel of a FieldPoint I/O Module:
lookout:\\130.164.44.8\FP\1AI\01
In this URL,
lookout
is the protocol,
130.164.44.8
is the IP address of
the FieldPoint Ethernet network module, and
FP\1AI\01
is the locator.
The FieldPoint Process part of a URL provides the parent folder from
which you access all data items in a FieldPoint bank. The FieldPoint
Process part of a URL has the following format:
\\[machine]\FP
where
[machine]
is the IP address or hostname of the FieldPoint Ethernet
network module.
The I/O Module Folder part of a URL provides the sub-folder from which
you access all data items from a specific FieldPoint I/O module. The I/O
Module Folder part of a URL has the following format:
\\[machine]\FP\[n]
where
[n]
consists of the numeric address and name of the I/O module. The
address of the I/O module is an integer from 1 to 9, where 1 represents the
I/O module closest to the network module and 9 represents the I/O module
farthest from the network module. The folder
\\130.164.44.8\FP\1AI
indicates the I/O module closest to the network module, and the AI means
that it is an analog input module.
The Channel Data part of a URL provides the scaled data value of the input
or output value for a specific channel. The Channel Data part of a URL has
the following format:
\\[machine]\FP\[n]\[channel]
where
[channel]
is a two-digit decimal number between 00 and 15.
The following figure shows a DataSocket URL with Channel Data.
