Parameters
8.3.2 12-1* Ethernet Link Parameters
12-1* Ethernet Link parameters
Option: Function:
Applies for whole parameter group.
[0] Port 1 Index [0] goes for Port IN.
[1] Port 2 Index [1] goes for Port OUT.
12-10 Link Status
Option: Function:
Read only. Displays the link status of the Ethernet
ports.
[0] No Link
[1] Link
12-11 Link Duration
Range: Function:
Size related [ 0 - 0 ] Read only. Displays the duration of the
*
present link on each port in dd:hh:mm:ss.
12-12 Auto Negotiation
Option: Function:
Configures Auto Negotiation of Ethernet link
parameters, for each port: ON or OFF.
[0] Off Link Speed and Link Duplex can be configured in
12-13 Link Speed and 12-14 Link Duplex.
[1] On
*
NOTE
It is recommended to set 12-12 Auto Negotiation to [0] Off
for the EtherCAT option and for the connected port. This
setting ensures that the connected ports are set to an
optimized Link Speed with Link Duplex setting. If only one
of the ports in a link is set to Auto Negotiation ON, the
ports can switch to half duplex, which results in poor
network performance. Most switches today have Auto
negotiation set, but it can then take longer to establish a
connection.
12-13 Link Speed
Option: Function:
Forces the link speed for each port in 10 Mbps
or 100 Mbps. If 12-12 Auto Negotiation is set to:
ON, this parameter is read only and displays the
actual link speed. If no link is present, "None" is
displayed.
[0] None
[1] 10 Mbps
[2] 100 Mbps

8.3.3 12-2* Process Data
12-20 Control Instance
Range:
100, 101, 103]
12-21 Process Data Config Write
Range:
NOTE
For configuration of 2-word (32-bit) parameter read/write,
use two consecutive arrays in 12-21 Process Data Config
Write and 12-22 Process Data Config Read.
12-22 Process Data Config Read
Range:
12-23 Process Data Config Write Size
Range:
16
12-24 Process Data Config Read Size
Range:
16

MG92A302 - VLT is a registered Danfoss trademark
Function:
Forces the duplex for each port to Full or Half
duplex. If 12-12 Auto Negotiation is set to:
[ON], this parameter is read only.
Half Duplex
Full Duplex
*
Function:
[None, 20, 21, Read only. Displays the connection to the
master. In Ethernet IP: If no CIP connection is
present, "None" is displayed. In EtherCAT: If no
connection is active "None" is displayed, else it
displays the active PDO.
Function:
[[0 - 9] PCD read 0 - 9] Configuration of readable process
data.
Function:
[[0 - 9] PCD read 0 - 9] Configuration of readable process
data.
Function:
[8 - 32 ] Sets the number of bits being sent from the
*
frequency converter as process data. The setting
counts from right (LSB). The value 1 means that
only the least significant bit of the signal is
transferred from the frequency converter.
Function:
[8 - 32 ] Sets the number of bits being sent to the
*
frequency converter as process data. The setting
counts from right (LSB). The value 1 means that
only the least significant bit of the signal is
transferred to the frequency converter. The
preceding bits are set to zero.
