Behavior of the PROFIsafe I/O module in the event of a failure
If an error is detected on a digital input or power output by the PROFIsafe I/O
module, the entire PROFIsafe I/O module is passivated by the process image of
all digital inputs being set to "0" and all digital power outputs being switched off.
For detailed information, read the section "Diagnostics".
7.4.5.3 Parameter Dual Channel Evaluation Ix & Ix+1
The Dual channel evaluation parameter is used to switch the dual channel
evaluation of the digital inputs on or off. The value of the parameter can be set to
"yes" or "no". If you have set the value of the operating mode parameter to
"Rotary table, you must set the Dual channel evaluation parameter to "no".
Depending on the value of the Dual channel evaluation parameter, the signal
states of the Ix and Ix+1 inputs are analyzed differently (normal, dual channel),
reproduced in the process image and transferred to the safe PLC.
If you have set the Dual channel evaluation parameter to "no", then the signal
states of the digital inputs are transmitted independently, i.e., single-channel
without analysis to the safe PLC (see Process Image section).
If have you set the Dual channel evaluation parameter to "yes", the respective
digital inputs Ix and Ix+1 are combined into an input pair by the PROFIsafe I/O
module. The signal states of the digital inputs are analyzed based on the rule set
using the Valence evaluation parameter and applied to the process image as 0
signal or 1 signal (see Valence Evaluation Parameter section).
The PROFIsafe I/O module can be used to create two input pairs from the four
digital inputs.
