4.3 The Configuration of the modules
The user can set the number and size of the I/O modules in the PROFIBUS
configuration tool. The settings of the modules are described below.
●
Max. I/O modules
：
32 modules
●
System setting module
：
20 Bytes output , 20Bytes input
●
Output module
：
1~16 Bytes, 32Bytes, 64Bytes, 64 Words
●
Input module
：
1~16 Bytes, 32Bytes, 64Bytes, 64 Words
●
Max. length of I/O data
：
480 Bytes
●
Output length
：
0~240 Bytes
●
Input length
：
0~240 Bytes
Note:
The user must add “System setting module” at the first module before the other
modules, else the I-7550E will send the diagnostic messages to PROFIBUS
Master and the system will be abnormal.
Example 1:
The user wants to read data with Maximum length of 20Bytes from Ethernet
device.
In this case, the user must select “System setting module” first, and can select two
modules: “Input Register => 16Bytes” and “Input Register => 4Bytes”; or an
“Input Register => 32Bytes”
Example 2:
The user wants to write data with maximum length of 10Bytes to Ethernet device.
In this case, the user must select “System setting module” first, and can select an :
“Output Register => 10Bytes”.
The user can set I-7550E as TCP/UDP server or client. TCP/UDP server allows
maximum 8 connections and I-7550E can have maximum 8 clients to
communicate with other TCP/UDP server. The user can setup TCP/UDP settings
form the web configuration of the I-7550E. For more TCP/UDP settings, please
refer to Chapter 5.
4.4 Diagnostic messages
The I-7550E can record maximally 10 diagnostic messages at the same time. If the
number of the diagnostic messages is bigger than 10, the I-7550E will not process
other diagnostic message. The diagnostic messages have three types. They are
“Connection ID Error”, “System Setting Module Error”, “Output data error” and
