Specification of the CAN-bus-interface

8.1. Bus interface

The smart-E high voltage generator is a CAN slave and to be factory provided with
Node ID 2 and set to a baud rate of 250 kBit/s. 50 kBit/s and 125 kBit/s can also be set.
Node ID and baud rate are set via co-called SDOs (see below) and always assumed
after a restart. All other parameters are immediately assumed.

8.2. Application interface

8.2.1.
8.2.2.
This generator uses the CAN open protocol for communication. After the 24 V CPU
supply has been applied, the recording processor starts and sends a boot up message.
The generator is now controlled via the receive-PDO "RXPD1" with the COB ID
"0x200+Node-ID".
Status information and measurements are saved by the generator in send-PDO
"TXPDO1 with the COB ID "0x180+Node-ID". These must then be requested by the
superordinate controls using SYN objects.
Other parameters are transferred via SDOs. Details are described in the object directo-
ry.
Operating manual 810378-BAL-EN-170330
CAN bus system always requires a connection resistance. This is
not integrated into the HV generator.

EDS-Files

Use our standardized "EDS" files to load the applications interface
to your control software.
EDS files are simple text files that use network configuration tools
to support the identification of products and their simple equipping
in a network.
SCHNIER provides an EDS file with all parameters and format in-
formation of the HV generator. It can be obtained on the smart-E
website www.smart-E310.de.
