New: Webserver with EnOcean-Monitor
Examples / Data access by MODBUS TCP
Our DBA driver for building automation
For sure you can use any third party PLC to read from and to write to the EnoDisc using the ESP3 standard (EnOcean Serial Protocol 3).
In a more convenient way, you can do this with our own control units.
On any device of our series VL-BASE, VL-SMART and VL-STYLE, you can easily setup the data communication channel to the EnoDisc using the pre-installed DEUTA DBA (Driver for Building Automation) on the device.
The DBA driver for building automation in detail – chapter EnoDisc
Besides many other functions, the DBA supports for sure also the EnoDisc. To read data from and to send data to EnOcean, a set of dedicated MODBUS TCP registers is used.
To be ready to receive data from an EnoDisc, you only have to setup the IP address, the EnOcean ID and the type of EEP of a sensor into the registers.
Then you have immediately direct access to the EnOcean data of the sensor (for more detailed information, please check the DAB driver’s manuak an the application notes).
The DBA driver for building automation in detail – abstract from the MODBUS register table
For your better understanding, below you will find an overview of the relevant MODBUS register tables for the EnoDisc. For more details, please check the DBA users manual.
|Receive / Rx||Transmit / Tx|
|9000 – 9063||IP addresses of the up to 32 EnoDisc||9000 – 9063||IP addresses of the up to 32 EnoDisc|
|9200 – 9263||EnoDisc EnOcean BASE ID’s||9200 – 9263||EnoDisc EnOcean BASE ID’s|
|9996 – 9999||LRN and Tech in support||11000 – 11999||EEP type of sensors / actuators in registers 10000+|
|10000 – 10999||EnOcean-ID’s of sensors / actuators||12000 – 12499||Index of the EnoDisc, which should send data n (0-31)|
|11000 – 11999||EEP type of sensors / actuators in registers 10000+||12500 – 12999||EnOcean ID for TX:|
EnOcean TX ID = BASE ID + value;
if value = 0x100 then EnOcean TX ID = BASE ID
|13000 – 13499||TX data according to EEP|
|9000 – 9063||Telegram counter of EnoDisc 0..31 (Reg. 9000 – 9063)|
|9100 – 9131||EnoDisc communication status|
|9200 – 9263||EnoDisc EnOcean Chip ID|
|10000 – 10999||Received sensor data acc. EEP (max. 500)|
|11000 – 11499||Telegram counter for each EEP (max. 500)|
|11500 – 11999||RSSI Level for each EEP|
Simpliest installation and bring-up
The power supply of the EnoDisc is realized by the communication interface cable (Cat. 5 or better) using Power Over Ethernet (PoE). In this way, you do not need line voltage to supply the EnoDisc, and you can reduce the effort for installation, bring-up and maintenance.
