We are trying to connect with intouch 8 to comm port1 using modbus rtu. On the secondary side of the comm port we have a data radio connected. Our problem is configuring the intouch and also the scripting part in intouch. We have got 4 slave radios that needs to be polled.

 

don't use the modbus ioserver from WW there are better 3rd party ones that allow for polling.

like one from standard automation or software toolbox

here is the list of all servers known to WW:

keep in mind WW will make a tag(data point) active if:

A DDE topic is set to Advise All Items;
A tagname is displayed in an opened application window;
A tagname is used in a Window or Action script and the application window that is associated with either script is opened;
A tagname is actively being used by a Real-time trend;
A tagname is used for alarming purposes;
A tagname is event logged and Event Logging is enabled;
A tagname is being logged in an Historical Log file and Historical Logging is enabled;
A tagname is used in a Key, Condition, Data Change, or Application script;
A tagname is an Auto Collection tagname in InTouch SPC;
A tagname is currently accessed by a client application (such as Microsoft Excel) using DDE.

 

Sir,

When I worked for Siemens We used a dde serial driver for this purpose. Try Here
