Table 43: Necessary Signal States for Acknowledgement if the Restart Inhibit is Set to "yes"

Input Pair
I1 & I2
I3 & I4
If you have set the Restart inhibit parameter to "No" acknowledgement of a
discrepancy error is successful once the deviation from the valence rule on the
digital inputs concerned no longer exists. You can set the value of the Restart
inhibit parameter for each input pair separately.

Operating Mode Parameter

Evaluation of the input signal state in the "Rotary table" operating mode!
If you have set the Operating mode to the "Rotary table" value, the temporal
logic evaluation of the signal state must be performed by a suitable function block
in the safe PLC. Under certain circumstances, you can use the process image of
the digital inputs without the suitable function blocks.
An overview for using F I/O modules in combination with a safe PLC is
summarized in an application note. This application note is available on the
Internet at
Notes..." .
You can use the Operating mode parameter to choose between safe standard
analysis of the digital inputs (single-channel, two-channel) and the specific
"Rotary table" operating mode.
If you want to use the digital inputs single-channel or two-channel, you must set
the Operating mode parameter to the "Standard" value.
The choice of operating mode only affects the digital inputs and clock outputs of
the F I/O module.
To connect the cam switch on a indexing table or one or more mode selectors to
the digital inputs of the F I/O module, set the parameter to the "indexing table"
value.
If you set the Operating mode parameter to "Round table", the F I/O module
behaves as follows:
The two-channel parameter is only accepted by the F I/O module with the
•
"no" value.
