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], [3]).

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 Part 1: Common Device Profile (CDP) V0.9.0 (→[12]) and

•ETG.5003 Part 2080: Specific Device Profile (SDP) Vacuum Pressure Gauge

V0.4.4 (→[13]).

2 Interface Connection

For operating the temperature controlled CDGxxxD gauge via EtherCAT, two

interface cables conforming to the EtherCAT standard are required.

If no such cables are available, make two according to the following indications.

Ethernet Patch Cable or Crossover Cable (CAT5e quality) with FCC68 connector.

Pin assignment of the D-Sub 15-pin sensor connector according to the

respective operating manual (→[1], [2], [3]).

Plug the EtherCAT (and sensor) cables connector into the gauge: From the

previous device the cable connected to OUT port has to be connected to the

CDGxxxD <IN> port. And the cable from the CDGxxxD <OUT> port has to

be connected to the next device's <IN> port.

3 Operation

Via the EtherCAT interface, the following and further data are exchanged in the

standardized EtherCAT protocol:

•Pressure reading

•Pressure unit (Torr, mbar, Pa)

•Zero adjustment

•Status and error messages

•Status of the switching functions

•Set Trip Point for switching functions

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.

During device initialization, the device address switches are read by the device

firmware. This device address is supported to the master as Explicit Device

Identification.

Example: Value of the Explicit Device ID = 0xDDD (dec 3549):
