Inhibit Time

For "Transmit PDOs", the "inhibit time" for PDO transmissions can be entered in this 16 bit field. If data is

changed, the PDO sender checks whether an "inhibit time" has expired since the last transmission. A new

PDO transmission can only take place if the "inhibit time" has expired. The "inhibit time" is useful for

asynchronous transmission (transmission mode 254 and 255), to avoid overloads on the CAN bus.

Event Timer

The "event timer" only works in asynchronous transmission mode (transmission mode 254 and 255). If the

data changes before the "event timer" expires, a temporary telegram is sent. If a value > 0 is written in this
