9.4.1.1 Additional process data
The SMN can send the following process data:
– Summary of the link states of all ports (three bytes) - each port corresponds to one bit
(0 - Link down; 1 - Link up)
Byte 1, 2, 3 1, 2, 3
Bit 7 6
Port 8/16/24 7/15/23 6/14/22 5/13/21 4/12/20 3/11/19 2/10/18 1/9/17
– The slots transmit link information for each port. This includes:
- Link status: (0 - Link down; 1 - Link up)
- Far end fault status: (0 - No fault; 1 - Fault)
- Port enable status: (0 - Enabled; 1 - Disabled)
- Link mode: (0 - Forwarding; 1 - Blocking)

PDEV function description

The PDEV function provides an extended scope of functions for switches in PROFINET
mode. This includes displaying neighbor and topology information in the engineering tool.
This information is determined using the Link Layer Discovery Protocol (LLDP) and can be
used, for example, to compare the desired and actual network.
In addition, the PDEV function is used to display the transmitted information via the respec-
tive Ethernet ports.
The PDEV function uses two new submodules:
– Interface submodule with port number 0x8X00 (X: from 0 to F)
– Port submodule with port number 0x8IXX (I: Interface ID; X: Port number)
These submodules are represented in the Step7 engineering tool. PROFINET communica-
tion enables information about the port speed, duplex mode, and the link status to be read.
An engineering tool reads and then displays the neighbor and topology information via
SNMP.
