Server Item Names
Server Items are made available when the "Server" Topic is defined. These items
give information about the Server and the current operational status of the Server.
PortType (R) - communication medium: "COM", "LPT", etc.
PortNo (R) - port number.
PollTries (R) - No. of missed polls before a device is considered offline.
NumberDevices (R/W) - number of devices in the system
OfflinePolltime (R/W) - how often to poll for off-line devices Milliseconds
NoDevicesOffline (R) - how many devices currently offline
Online (R) - indicates if communicating with any devices (0 or 1)
Ready (R) - 0 indicates that OMWT-SOFT-OPC is not receiving
(initializing or do a restart function); 1-OMWT-SOFT-OPC is ready to
receive.
CntNode – the number of nodes OMWT-SOFT-OPC is maintaining. For
TCP/IP Receiver, this is the number of connections to receivers. Use
this number to access the Noden items.
Noden.online (R) – indicates if the node is online or offline (0 – offline; 1 –
online). n is the node number starting at 1.
Noden.address (R) – address of the nodeFor TCP/IP Receiver, the address
is the IP address. n is the node number starting at 1.
