Channel_n_ResMode BOOL Set channel n to resistance mode
Channel_n_Filter USINT
Set filter for channel n.
The arithmetic mean is output after n+1 conversions

Module-Specific Messages
Apart from the Module error messages, the set of messages below contains details about the current
state of the PACIO AI4-Pt/Ni100 16 Bit and PACIO AI4-Pt/Ni1000 16 Bit Modules. These messages are
automatically reset when the state concerned has returned to normal. They are combined into a single
"Specific_Error" state and output to the IO LED as "Module-
Variable Data type Explanation
Channel_n_Open BOOL
- Channel n load is gt minimum
- Broken wire of connector 0 *
- Broken wire of connector 3 *
- Broken wire of connector 0/3 *

Specific_Error = TRUE
Channel_n_Shortcut BOOL
- Channel n load is lt minimum
- Short circuit of connector 0-3 *
- Broken wire of connector 2 *

Specific_Error = TRUE
*The causes of 'short circuit' and 'broken wire 0.3' are shown for channel 0 (equivalent applies to other
channels).
Conversion Time
The analog signals are converted one by one down every channel. Disabling one or several channels will
shorten the entire analog-to-digital conversion cycle.
'Filter' in this case means to compute an average when the set filter time is over.
Analog value conversion runs cyclically and is not synchronized with the receipt of EtherCAT telegrams.
The cycle consists of the analog value conversion plus transmitting the values into the EtherCAT data area.
