PCAN-USB arriving continuously the same message

[Oprogramer]

Hello,

i have a probelm with the PCAN-USB Adapter. I have two PCAN-USB Adapter running on two computers, one is in listen only mode and the other one sends CAN messages.

My Issue is when i send CAN messages throw the PCAN-USB Adapter every 500 milliseconds and the modul which is connected to the Bus is in sleep mode then i get continuously every 0,2 milliseconds the same Message i have send. It is always the first message. When i send more messages then i only get the first which is been sending.

When i disconnect the modul from the CAN-BUS then it shows the same behavior. Even when i change the cycle time of sending message to something else it dosent change the arriving of the same message every 0,2 milliseconds.

But when i switch the PCAN-USB Adapter from listen only mode to normal mode and the modul is connected to the CAN BUS, then it works normal.

Is theire any configuration that i have forgot?

A CAN Network need minimum TWO active CAN nodes. If you set one of your two devices to Listen Only Mode, then it will not ACK the Message the other node try to send. So the other nodes send it again and again and again... This is a normal behavior of CAN Networks.
