With this setting, the Receive PDO is configured to overtake the received data coming in
by COB-ID 201 into the ID 503. The number of mapped objects is here 1.
Refer to ╚═▷ “9.2.9 Additional Data Identifier” for a list of additional
parameter groups.
CANopen message
The following table shows four data examples the device is receiving on the CANopen
bus. These data are sent as TPDO to the device (COB-ID 201). The settings above map
the received data to the easYgen address ID 503.
ID (hex) Description Data (hex)
201 Remote Start 01 00
201 Remote Stop 02 00
201 Remote Acknowledge sequence of:
0000, 10 00; 0000, 1000
Notes
The message 1000hex must be sent
twice to acknowledge an alarm
completely. The first rising edge
(0000hex followed by 1000hex) disables
the horn and the second rising edge
resets the alarm.
201 Remote Shutdown 00 02
6.4.1.1.2 Default SDO Communication Channel
Another possibility for a remote start/stop/Acknowledgment is to send the request via
default SDO communication channel. The device listens to the CAN ID 600 (hex) + Node-
ID internally to perform the desired control, the reply is on CAN ID 580 (hex) + Node-ID.
The following examples show the request format on CANopen with different Node-IDs.
The request on the bus is sent via the control parameter ID 503 of the device.
The value 2000 (hex) is calculated internally:
• 503 (dec) -- 1F7 (hex) •
• 1F7+2000 (hex) = 21F7 (hex) •
Please note that high and low bytes are exchanged in the sent address. The data (hex)
shows the state of parameter 503 to achieve the required control.
Node-ID 1 (standard value)
The following table shows exemplary request data for the device on the CANopen bus.
