Parameter configuration description
The ports of the SRI8400-8A0B can adapt to various modes.
| Interface | Parameter setting description |
|
X01~X08 |
IO-Link: The interface is used for IO-Link communication and can connect IO-Link modules; If IO-Link mode is selected for a port and I/Q Config is set to Class A, pin 2 of that port can be used as I/Q Input, a digital PNP-type input. If IO-Link mode is selected for a port and I/Q Config is set to Class B, pin 2 of that port provides a 24 V output. Input: C/Q Input: interface pin 4 is configured as digital PNP input; I/Q Input: interface pin 2 is set as a digital PNP-type input (default); I/Q Output: interface pin 2 is configured as digital PNP output; C/Q Output PNP: C/Q Output: interface pin 4 is configured as digital PNP output; I/Q Input: interface pin 2 is set as a digital PNP-type input (default); I/Q Output: interface pin 2 is configured as digital PNP output; C/Q Output NPN: C/Q Output: interface pin 4 is configured as digital NPN output; I/Q Input: interface pin 2 is set as a digital PNP-type input (default); I/Q Output: interface pin 2 is configured as digital PNP output; |
Note:
- The default is IO-Link mode; pay attention to the port Class type when using.
- PIN2 I/Q defaults to I/Q Input; to set it to I/Q Output, this function must be enabled on the web page, and I/Q output must be selected under the "I/Q Config" directory of the corresponding port.
Address arrangement description
| Input area address arrangement | Description | |
| Local DI | 2 bytes | PIN 4, PIN 2 input addresses |
| ISDU information | 34 bytes | / |
| Event information | 10 bytes | / |
| Diagnostic information | 13 bytes | This address is occupied only after the diagnostic information function is enabled on the web page |
| IO-Link Port DI | Length calculated based on configuration | Input addresses of connected slaves |
| Output area address arrangement | Description | |
|
Local DO |
Max. 2 bytes |
Note: (default 1 byte; after the I/Q output is enabled on the web page, the local DO occupies 2 bytes, and subsequent addresses shift forward in order) Byte1: local digital output address (C/Q Output-PIN4) Byte2: local digital output address (I/Q Output-PIN2) |
| ISDU configuration | 40 bytes | / |
| Event configuration | 4 bytes | / |
| IO-Link Port DO | Length calculated based on configuration | Output addresses of connected slaves |
EIP data length configuration description
- Input data length (InputData) = 2 (local PIN4/PIN2 input addresses) + 34 (ISDU information) + 10 (event information) + 17 (diagnostic information) + sum of input bytes of IO-Link port1 to port8;
- Output data length (OutputData) = 1 (local PIN4 output address) + 1 (local PIN2 output address) + 40 (ISDU configuration) + 4 (event configuration) + sum of output bytes of IO-Link port1 to port8;
Note:
(1) This master supports a maximum of 500 bytes each for input and output address lengths; exceeding the byte length will cause communication abnormalities.
(2) The data addresses of the input/output area are arranged in sequence in this order.
Diagnostic information and I/Q outputs occupy the corresponding addresses only after this function is enabled on the web page; if not enabled, they do not occupy the addresses, and all subsequent addresses automatically move forward in sequence.
