2. Important safety informaon
2.1 General informaon
CAUTION: DATA TRANSMISSION ERRORS
Risk of transmission errors. Any aempt to simultaneously operate the gauge with
the RS232C serial interface and EtherCAT may result in incorrect data and data
transmission errors.
So do not simultaneously operate the gauge with the RS232C serial interface and
EtherCAT interface.

3. Descripon
3.1 Intended use
This communicaon protocol contains instrucons for operang EtherCAT secondary
interfaces together with a primary interface.
Note:
For safety informaon, specicaons and operaon instrucons of the vacuum gauges
refer to the respecve manual.
3.2 EtherCAT interface
The following descripon of the EtherCAT interface is compliant with the EtherCAT
specicaon of the EtherCAT Technology Group (ETG) and the EtherCAT Semiconductor
Device Prole.
This manual describes the funconality of an EtherCAT secondary interface and
supports:
▪ ETG.5003.1 S (R) V1.1.0: Part 1 Common Device Prole (CDP) and
▪ ETG.5003.2080 S (R) V1.3.0: Part 2080: Specic Device Prole (SDP) Vacuum
Pressure Gauge.
For operang the gauge with EtherCAT, prior installaon of the device specic ESI le is
required on the bus master side. This le can be downloaded from our website.
3.3 Validity
This document applies to products of the Barocel 7025, Barocel 7045 and Barocel 7100
series with EtherCAT interface. This manual is based on rmware version 1.3.0.0.

4. Interface connecon
Making an EtherCAT interface cable
For operang the temperature controlled Barocel 7045/Barocel 7100 gauge through
EtherCAT, two interface cables conforming to the EtherCAT standard are required.
If no such cables are available, make two as follows:
1. Cable type - Ethernet patch cable (CAT5e quality) with FCC68 connector.
2. Procedure:
▪ Pin assignment:

W60990880_A - Interface connecon

▪ Plug the EtherCAT (and sensor) cables connector into the gauge:
From the previous device, the cable connected to the OUT port must be
connected to the Barocel <IN> port. And the cable from the Barocel <OUT> port
has to be connected to the next device's <IN> port.

6. Operaon
CAUTION: DATA TRANSMISSION ERRORS
Risk of transmission errors. Any aempt to simultaneously operate the gauge with
the RS232C serial interface and EtherCAT may result in incorrect data and data
transmission errors.
So do not simultaneously operate the gauge with the RS232C serial interface and
EtherCAT interface.
Through the EtherCAT interface, the following data is exchanged in the standardised
EtherCAT protocol:
▪ Pressure reading
▪ Pressure unit (Torr, mbar, Pa)
▪ Zero adjustment
▪ Status and error messages
▪ Status of the switching funcons
▪ Set trip point for switching funcons.

6.2.5 Device address switch
During device inialisaon, the device address switches are read by the device rmware.
This device address is supported to the primary interface as Explicit Device
Idencaon.
Example: Value of the Explicit Device ID = 0xDDD (dec 3549):
0x100 * 0xD (dec 3328) + 0x10 * 0xD (dec 208) + 0x1 * 0xD (dec 13)

7. Object structure Barocel 7025, Barocel 7045, Barocel
7100
This chapter describes the CANopen over EtherCAT (CoE) object diconary.
7.1 Object diconary structure
The objects in the CoE object diconary can be accessed with SDO services and many of
the diconary objects can be mapped for cyclic communicaon in PDO's. Each object is
addressed using a 16-bit index and an 8-bit subindex.
The following table shows the overall layout of the standard object diconary.
Index (hex.) Object diconary area
1000 – 1FFF Communicaon prole area
2000 – 5FFF Manufacturer-specic prole area
6000 – 6FFF Prole Specic
Area
Input area
7000 – 7FFF Output area
8000 – 8FFF Conguraon area
9000 – 9FFF Informaon area
A000 – AFFF Diagnosis area
B000 – BFFF Service Transfer area
C000 – EFFF Reserved area
F000 – FFFF Device area
Explanaons for the abbreviaons are as follows:

7.2 Communicaon prole objects (0x1000…0x1FFF)
The objects of the communicaon prole describe the basic EtherCAT properes of the
Barocel and are common to all EtherCAT secondary interface using the CoE
communicaon protocol. The objects are described as follows:

7.2.1 Process Data Objects (PDO's)
Barocel gauges only: They consist of one vacuum pressure sensor with an addional
sensor measuring the ambient pressure (ATM). For each sensor module, a default
mapping is congured.
Or to meet other requirements the T x PDO's 1A01, 1A03 or 1BFF and the R x PDO 1601
are designated for user mapping. These PDO's do not have default values and can be set
up by the PDO conguraon.
