Caution
 
Caution: data transmission errors 
Any attempt to simultaneously operate the gauge via the RS232C 
Serial Interface and EtherCAT interface 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 EtherCAT interface, or the diagnostic 
port. 
 
 
 
 
 
This Communication Protocol contains instructions for operating EtherCAT inter-
faces (slaves) together with a master. 
 
  For safety information, specifications and operation instructions of the 
vacuum gauges refer to the appropriate documents (→  [1], [2]). 
 
 
 
 
The following description of the EtherCAT interface is compliant to the EtherCAT 
specification of the EtherCAT Technology Group (ETG) and to the  "EtherCAT 
Semiconductor Device Profile". 
This manual describes the functionality of a EtherCAT slave and supports 
•  ETG.5003.1 S (R) V1.0.0 : Part 1 Common Device Profile (CDP) (→  [11]) 
and  
•  ETG.5003.2080 S (R) V1.0.0 : Part 2080: Specific Device Profile (SDP): 
Vacuum Pressure Gauge (→  [12]).
