Description
Node
The current node being displayed out of the total.
Adapter

Node_Name
The node name specified in the CSV file.
Node_ID
The station number or address of the node. The actual meaning is
dependent on the driver and protocol – refer to the Driver Manual.
dependent on the driver and protocol – refer to the Driver Manual.
Protocol
The protocol being used to update the data for that node.
Refer to the Driver Manual
Refer to the Driver Manual
IP_Address
The IP address used by this node.
Remote_IP_Address
The remote IP address used by this node
Node_Type
Specified in the configuration file as the PLC_Type. - Consult the driver
manual for additional information.
manual for additional information.
Port
Port number for a serial connection.
Readback_Option
After a write has been executed in a write through operation, the
FieldServer schedules the read Map Descriptor to poll again in order to
immediately read back the data that was written. The default is
‘Readback_on_Write”. Other options are “None” and
“Expire_Current_Data”

Retries
Tells the driver how many times to retry a poll before considering the
node to be offline. The default is 3.

Preambles
Counts data bytes received before a valid message, but not forming part
of a valid message, e.g. a message fragment.

MAC_Address
Currently this field is not used at all. It is intended to allow drivers to
resolve an IP address by giving a MAC address.

Phone_Number
This field is intended for modem support. Currently disabled.
Srv_Offline_Method
The method used on the node to decide if it is to be considered offline.
Node_Offline_response
The type of response the server side of the driver sends when it finds
the downstream node to be offline.

Timeout
The timeout specified for the node. Refer to Error! Reference source

Retry_Interval
The amount of time in seconds that the driver should wait before
retrying a poll after a timeout has occurred
retrying a poll after a timeout has occurred
Recovery_Interval
The time in seconds after a node goes off-line before the driver tries to
poll the device again. – default 30seconds.
poll the device again. – default 30seconds.
Probation_Delay
The length of time communication needs to be re-established for before
an offline Client node is marked on-line again. Default 1 minute.
an offline Client node is marked on-line again. Default 1 minute.
Network_Number Network
station number used on this node.
Server_Name
An alternate to specifying the IP address. Typically used when the user
wants two nodes to talk to each other. When specified, the FieldServer
sends out a broadcast with the server name and uses the reply to fill in
the IP address for the node. Until the reply has been received all polling
for the node is disabled. The server name given should correspond to
the pair_name specified in the remote FieldServer’s bridge settings.

Alias_Node_ID
This is used to distinguish between different nodes connected to the
FieldServer when a PLC does not support the allocation of different
None_ID’s. Each node is given a different alias. Upstream devices poll
the Alias_Node_ID and the FieldServer routes the poll to the correct
PLC which is polled using the Node_ID.
