Node 

The current node being displayed out of the total. 

Adapter 

The adapter name where a node is connected to an 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. 

Protocol 

The protocol being used to update the data for that node.  
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. 

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 
not found.. 

Retry_Interval

 

The amount of time in seconds that the driver should wait before 
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.

 

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. 

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. 

Ports_on_PLC 

For hot standby operation.  This field is used to control which port on a
