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.

 

 

 

 

 

After a write has been executed in a write through operation, the

 

FieldServer schedules the read Map Descriptor to poll again in order to

Readback_Option

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.

 

 

 

 

An alternate to specifying the IP address. Typically used when the user

 

wants two nodes to talk to each other. When specified, the FieldServer

Server_Name

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.

 

This is used to distinguish between different nodes connected to the

 

FieldServer when a PLC does not support the allocation of different

Alias_Node_ID

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
