Operation using Commuwin II

When operating using the Commuwin II display and operating program the Cerabar M is calibrated and operated:
· via an operating matrix or
· via the graphics operating mode.
The appropriate server (e.g. HART or ZA 672) must be activated. A description of the Commuwin II operating program is found in the operating manual BA 124F. Operating matrix The advanced functions of the Cerabar M can be accessed in this operating mode in the menu.
· Each row is assigned to a function group.
· Every field displays a parameter.
The calibrating parameters are entered in the appropriate fields.

Operating with the HART protocol via Universal HART Communicator DXR 271
