CONTROL WITH CAN COMMANDS

The load valve can be fully controlled via the CAN bus.
Various data are defined and transmitted to the control box via CAN bus. The load valve is able to follow a pre-

defined load curve (ramp or sine). In addition, it is possible to process the load curve cyclically, i.e. identical

loads can be run several times in succession.

CAN - Setup

Baud rate: 125 kB (not changeable)
Node ID:

0x20 (cannot be changed)

TPDO1:

0x1A0 Valve voltage

TPDO2:

0x2A0 Status information

Heartbeat:

0x720 (every 1000ms) DLC=8

Heartbeat

The current operating mode is transmitted in byte [0]

0x02: Configuration parameter not loaded
0x03: Calibration data for DAC not set
0x04: Standby (OFFLINE)
0x05: Connected (ONLINE: Parameter are activated, waiting for START)
0x06: Activated (LoadValve is running)
0x07: ConfigMode active
0x80: TimeoutCounter

In operating mode "2", and "4" the firmware version is transmitted as ASCII text in Byte [1..7]

.B. "1.4 011".

The operating mode can be queried specifically via object 0x2050/1.

Answer: 4 Bytes:

Byte [0]: Operating mode
