Caution
Caution: data transmission errors
Any attempt to simultaneously operate the gauge via the RS232C
Serial Interface and a Fieldbus interface (DeviceNet or Profibus) or the
diagnostic port may result in incorrect data and data transmission
errors.
Therefore, it is inadmissible to simultaneously operate the gauge via
the RS232C Serial Interface and DeviceNet, Profibus, or the diag-
nostic port.
This Communication Protocol contains instructions for operating DeviceNet inter-
faces (slaves) together with a master.
This manual describes the functionality of DeviceNet for programming
purposes. For more information → "DeviceNet Specifications" of the
Open DeviceNet Vendor Association (ODVA).
For safety information, specifications and operation instructions of the
vacuum gauges refer to the appropriate documents (
→ [1], [2], [3]).
The following description of the DeviceNet interface is compliant to the DeviceNet
specification of the Open DeviceNet Vendor Association and to the "Interface
Guidelines for DeviceNet Devices On Semiconductor Manufacturing Tools".
