Channels Configuration

Protocol Options

  • Maximum size of blocks: Defines the maximum number of addresses in a read block.
  • Message Format: defines the protocol used for the Data Sockets communication:

    • LOOKOUT
    • HTTP
    • FTP

Settings

TCP/IP:

  • NodeConnections: Defines the maximum number of parallel requests that will be sent to each node (asynchronous communication)


Nodes Configuration

Station Configuration 

TCP/IP:

Station syntax: <IP address>

Where :

  • <IP address>: IP address of the slave device in the network

You can also add /<Branch> at the Station name.

E.g.:  192.168.1.1

122:168.1.1/MyTags


Points Configuration

The syntax for the communication point is: InitialBranch/TagList/Tag1


NOTE

If you have many tags sharing the initial branchs, you can also remove the InitialBranch from the Point address and move it to the Node-Station address.
