Byte 7 indicates this data is from which Ethernet Device, Byte 13 and Byte 15 is
the length of the data received.
3.5.2 Package received with “Partition Method”
When the I-7550E receives the data that its length is over the configured input
data length, the I-7550E will partition this data into several packages. The user
can know the information of packages from input data area of “System setting
module”.
In this example, we assume the input data length is configured as 220 Bytes and
the I-7550E receives a data with 420 Bytes from connection ID 1. That means
the I-7550E will partition this data into 2 packages. And these 2 input data of
“System setting module” are as shown
Table 19 and Table 20 .
Byte 1 is Read message ID and it will be the same in these 2 package headers. It
will let the user know these 2 packages are actually the one data from Ethernet
device. The user can handle these data depending on these values of input data
area.
