Tool Routing Service for AC 800M
In order that field devices can be accessed with DTM via the AC 800M controller, the communication path (Tool Routing) must be enabled in each controller.
In 800xA system, communication with field devices through DTMs is possible, only when Tool Routing is enabled.
Tool Routing is disabled by default. In order to activate it, the processor module of the AC 800M controller, e.g. PM860/TP860, is selected in Control Structure.
The Control Properties aspect appears in the aspect window. Select the aspect to open an overview of the various properties of the module in the main Plant Explorer window. One of the property entries is TOOLROUTING.
Set this Property Valueto Enabled and click Apply.
Increase TOOLROUTINGNBRCON to 50, if more than 20 HART and PROFIBUS devices containing a DTM are placed below the connected AC 800M controller.
