For adding the RSTi-EP Input and/or Output modules to the Network adapter, calculation
of total data size for input and output is required.
For Example- To add RSTi-EP Digital Input module EP-125F (Process Input Data size-2
Bytes) and RSTi-EP Digital Output module EP-225F (Process output Data size-2 Bytes), so
the total input data size will be 4 bytes ( 2 bytes (for adapter) + 2 bytes (EP-125F)) and total
output data size will be 4 bytes (2 bytes (for adapter) + 2 bytes (EP-225F)). So total input
data size will be 4 bytes and total output data size will be 4 bytes for input assembly 101
and Output assembly 102 respectively.
To add more input and output modules, only the input and output size have to be
incremented depending upon the data size of the module. Refer to section, data width of
RSTi-EP IO modules under the EPXEIP001 EtherNet/IP adapter. Download the
configuration and Read/Write the Cyclic data (in defined Registers).
In order to Read/Write the Acyclic data (device data, Diagnostics data, parameter data) ,
use the Programing block (if engineering Tool supports). To configure programming
block, typically you need to provide below parameters depending upon the data
read/write.
a) Message Type
b) Service Type
c) Class
d) Instance
e) Attribute
f) Source Element
g) Source Length
h) Destination Element
i) Communication Path
