1. ISDU fast processing

This mode decreases a request time for ISDU Read/Write.

The difference with and without fast processing mode:

Mode

Device: COM3

Min. cycle time:           1 ms

On Request length:     2 bytes

Process Data Length: 4 bytes

Sequence Read/Write “Application tag”
32 bytes (100 times)

Normal mode

Fast processing ON

2. ISDU cached mode

This mode is useful, when ISDU data is used only for writing (reading data in this mode is not supported), for example BLOB writing or Firmware update

The difference with and without cached mode with firmware update:

Mode

Device1: COM3

Min. cycle time:           6,8 ms

On Request length:     2 bytes

Process Data Length: 0 byte

Firmware update 64 kb,

Transmission only time – the code will not be written into flash

3. Send broken M-SEQ during IO-Link communication

This mode helps to detect if IO-Link device properly reacts on interferences:

Invalid messages can be each 0 (disabled), 1, 2 or 3 for 3 messages sequence

  • Wrong CRC
  • Invalid message size
  • Invalid M-SEC type with wrong CRC
