Driver dialog PVI
|Show all Hide all|
The checkbox "with Eventmode" allows to switch the driver from polling mode to spontaneous mode. The driver always communicates spontaneously with PVI ! The checkbox has the effect, that the data transfer between PLC and PVI is also spontaneous (the PLC will only send a value to PVI if the value has changed). Attention - this has to be supported by the PLC. You may need a new firmware for that. If you are not sure, please contact Bernecker & Rainer. If you want to use hysteresis, you have to switch to Eventmode.
