6032
Ethernet Port 2 Full Duplex
Enabled
BOOL RO
Actual duplex mode. This is a read only parameter. True = Full Duplex
False = Half Duplex
6033
Ethernet Port 2
Autonegotiate Enabled
BOOL RW NV
Default: 1
Config CRC
Admin Lock
USB Lock
Selects Auto-Negotiation of link speed and duplex. False = Disabled
True = Enabled (default)
6034
Ethernet Port 2
Autonegotiate State
UINT8 RO
Enum
Active state of the Auto-Negotiation behavior. This is read only.
6035
Ethernet Port 2 Enable
BOOL RW NV
Default: 1
Config CRC
Admin Lock
USB Lock
This parameter is used to disable the Ethernet port. True = Enable Port
False = Disable Port
6036
IP Conflict Detection Enable
BOOL RW NV
Default: 1
Config CRC
Admin Lock
USB Lock
Address Conflict Detection enable. ACD provides protection from
duplicate IP addresses on the network. 0 = Disable ACD, 1 = Enable ACD.
6037
IP Conflict Detection Status
UINT8 RO
Enum
Address Conflict Detection State. This is read only. 0 = no conflict
detected, 1 = conflict detected - defending, 2 = conflict detected -
retreated.
6038
IP Conflict Detection
Conflicted Status
UINT8 RW NV
Default: 0
Range: 0 to 0
Address Conflict Detection Status. The state of ACD activity when the last
conflict was detected.
6039
IP Conflict Detection
Conflicted MAC
UINT8 RW NV
Array size: 6
Default: 0
Range: 0 to 0
Address Conflict Detection conflicted device MAC address. The source
MAC address from the header of the received Ethernet packet which was
sent by a device reporting a conflict. All Ethernet devices have a unique
MAC address so by reporting the MAC address of the device containing
the duplicate IP address allows the issue to be resolved in a timely
manner.
Array of 3 registers
6048
Ethernet MAC Address
UINT8 RO
Array size: 6
Unique MAC Address assigned to this device.
Array of 3 registers
6052
Profibus Modbus Timeout
UINT16 RW NV
Default: 2000
Units: ms
Backup Mem
The time before Modbus communications are considered lost. Every valid
message received will reset this timer. The timeout is based on
milliseconds. When this timer expires, communication loss behavior will
be triggered. A value of zero (0) will disable the communication timeout.
