If the operating mode of the fieldbus is büS, then the CANopen status is set to Operational and the
PDOs are sent to büS.
If the operating mode of the fieldbus is CANopen, then the CANopen status is set to Pre-Op until the
CANopen network master switches the product to Operational .
8.7 Transmission speeds of cyclic data
The product transmits cyclic data at the following transmission speeds:
▪ once every 500 ms by default if the value of a PDO is constant. The transmission speed of each PDO
can be changed. Refer to
Change the transmission speed of a single PDO [
}
39]
▪
once every 100 ms by default if the value of a PDO changes. If the bus load does not exceed 50%, then
the transmission speed can be increased temporarily to 10 ms. Refer to
Temporarily increase the
transmission speed of all PDOs [ } 39]
8.7.1 Change the transmission speed of a single PDO
In the Bürkert Communicator software, select the product.

▪ If the bus load is higher than 45%, then do not increase the transmission speed.
▪ If the bus load is less than or equal to 45%, then the transmission speed can be increased. Do the fol-
lowing procedure:
In the Bürkert Communicator software, select the product.
The product status indicator flashes.
Go to General settings > Diagnostics > Inhibit time .
To increase the transmission speed, click Set diagnostic mode . The function Inhibit time switches to
