C-16 EtherNet/IP Communications Module
N201 – N212 These N-files let you read and write parameter values in DPI Peripherals (for
example, an OIM or module) as 32-bit double words. You can interpret the
data in various ways (for example, 32-bit real, 32-bit integer) To read a
parameter, you need to send a message with two elements. For example, to
read parameter 1 in the peripheral connected to DPI port 1, read two
elements beginning at N201:2. As another example, to read parameters 2 – 6
in the peripheral connected to DPI port 5 (the module), read ten elements
beginning at N209:4.
