Input 1 and input 2

The digital inputs Input 1 and Input 2 (terminal points 2 and 6) only work if the 24 V supply voltage is connected and the K-bus voltage supplied is switched on.

Input 1 and input 2, effect on automatic mode

The digital inputs Input 1 and Input 2 (terminal points 2 and 6) have priority over automatic control through the PLC program. If the digital inputs are operated, other PLC-controlled SMI commands are blocked. To enable them a rising edge is required at the bResetInactiveProcessImage input of FB_KL6831KL6841Communication.
