Description
This block gets the requested data from another station using Sutron Standard Protocol (SSP)
communications. The properties for the block specify the port to use for the communications and
the path or station name. The port can be specified only if you have first set up ports in the Coms
(SSP/CL) entry on the Setup tab. The path can be a simple station name, or a station with full
path information included (such as \
patha \ pathb \ stationx ). When the Port selection is “TCP/IP”,
enter the URL to the destination. The Tag property must match the name specified in a COMS
Tag in the named station.
For example, Station 1 is measuring water level and Station 2 wants to get the water level for its
own use. Add a COMS Tag after the measure of the water level in Station 1. Set the COMS TAG
Name property as WaterLevel. In Station 2, add a GetTag block connected to a measure. In the
GETTAG properties, set the Tag property to WaterLevel. Also set the port and path for the link
between the two stations. Now, whenever the GetTag block runs, the code will communicate to
the named station and ask for WaterLevel. The station will reply with the data for WaterLevel
and then the GetTag block will provide the data to connected blocks.
