genslread - Generate Simulink OPC Read block from MATLAB group object
Syntax
BlkPath = genslread(GrpObj)
BlkPath = genslread(GrpObj, DestSys)
Description
BlkPath = genslread(GrpObj) generates
an OPC Read block from the dagroup object GrpObj,
and places the block in a new Simulink model. The OPC Read block
has the same name, update rate, and items as GrpObj.
If all items in GrpObj have the same data type,
the OPC Read block's Value port indicates that
data type. BlkPath indicates the full path to the
new OPC Read block.
BlkPath = genslread(GrpObj, DestSys) generates
the OPC Read block and places it into the system defined by DestSys. DestSys must
be a model name or a path to a subsystem block. The OPC Read block
automatically takes a location that attempts to minimize overlap of
lines and blocks, however, the block might appear over an existing
annotation.
Examples
Create a group object with two items, and then construct an
OPC Read block from the group:
da = opcda('localhost', 'Matrikon.OPC.Simulation');
grp = addgroup(da, 'ExOPCREAD');
itm1 = additem(grp, 'Triangle Waves.Real8');
itm2 = additem(grp, 'Saw-Toothed Waves.Int2');
% Set update rate to 2 seconds:
grp.UpdateRate = 2;
% Construct OPC Read block:
blkPath = genslread(grp)
