Title: Advanced TCP/IP Data Logger - how to specify data from different IP addresses? Post by: davidho on November 23, 2009, 01:07:44 AM Hi there,
I've purchased the enterprise verison of TCP/IP data logger and want to receive data from 4 data servers at different IPs, and my main purpose is to transfer these data, via OPC service, to Wonderware ArchestrA server. The Data servers are Wind Speed Sensors, constantly sending ASCII string out to a specified IP address (e.g. TCP/IP data logger). Questions: Should I specify 4 IPs in one single configuration, or 4 separate configuration with 1 IP each? And how to transfer strings into different OPC variable. (I know I can use FULL_DATA_PACKET, but how to make sure each wind sensor's data goes to a single item?) It will good to have some examples to follow with) Title: Re: Advanced TCP/IP Data Logger - how to specify data from different IP addresses?

1. To create 4 different configurations for each IP address and activate the OPC server within first configuration only; 2. To define a parser item that will contain all your data (look at an image); 3. To redirect data from 2-4 configurations to first configuration (second image).

I also found there is a tick box in "ASCII" parser function to add port number when received data.
It caused me a few hours of headache not knowing I was running both aipdlog.exe as service and as application, which causes problem on getting 3rd party OPC client to read OPC tags properly. |
