PROFINET example
The PROFINET example consists of the following:
● 16 PROFINET slave devices named "et200s_1" through "et200s_16"
● The 16 PROFINET devices use PROFINET device numbers 1 through 16, respectively.
● Each slave device is configured with multiple I/O modules.
● The first four bytes of the returned STATE parameter information is displayed.

0xFFFF_0100 0xFFFF_0100 0xFFFF_0100
2 - Device defective

0x0300_0000
0x0300_0000
3 - Device disabled
0x0000_0000
0x0000_0000
0x0000_0000
4 - Device exists 0xFFFF_0100 0xFFFF_0100 0xFDFF_0100
5 - Problem in device
0x0000_0000
0x0300_0000
0x0300_0000
The following four tables show a binary breakdown of the four bytes of data that are being
analyzed:
Table 9- 163 Example 1: No errors: A value of 0xFFFF_0100 is returned for MODE 1 (Device configu-
ration active).
Byte with value
Bit pattern with value
Notes
Byte 1 0xFF
Bit 7 1111-1111 Bit 0
Bit 0 is true; data is available.
Byte 2 0xFF
Bit 15 1111-1111 Bit 8
Byte 3 0x01
Bit 23 0000-0001 Bit 16
Byte 4 0x00
Bit 31 0000-0000 Bit 24
The devices are configured in addresses 1 (Bit 1) through 16 (Bit 16).
No devices are configured in addresses 1 through 9.
MODE 4 (Device exists) data matches MODE 1 (Device configuration active), so the configured
devices match the existing devices.
