5.3.15 Module 14
– analogue input master 1
Data content
Analogue input data of the analogue slaves to AS-I master 1
Note
With module 14 the data of the analogue input slaves on AS-i master 1 with the following AS-i
slave addresses can be directly read:

1...31 (setting 4 channels per slave),

1...31 (setting 1 channel per slave).
Change of the setting "Channels per slave" (
→ page
93 )
If an analogue input channel is to be read outside the ranges indicated above, module 9
(analogue multiplexed input) must be used for reading these data.
Direction of data
Data from the controllerE to the fieldbus interface
Module settings
Value range 0…31
4 words of data for 4 channels per slave
2 words of data for 1 channel per slave
0 module is deactivated
1…31 module is activated (details → data interpretation)

The following table shows an assignment example of analogue data within the PDOs under the
following conditions:

setting 4 channels per slave

start address of the module is on the first byte of a PDO (bytes 0, 8, 16, 24, ...within the
DP RAM)

Example for module 14
Task 1:
The value 12 is specified for module 14. The setting for channels per slave in the CoDeSys
configuration window is equal to 1. What is the highest AS-i slave address whose data can be
transmitted with this setting and how many words are transmitted in total?
Solution: The highest AS-i slave address is 12. 24 words are transmitted.

in the table "table for input data for 1 channel / slave"
Task 2:
To which minimum value must module 14 be set so that the data of the analogue input slave
with the AS-i address 10 can be read (setting 4 channels per slave)? In which word in the range
can the data of channel 3 of the said slave be found?
Solution:
The value to be set for module 14 is 10. The data of slave 10, channel 3 can be found in word
38 of the range.
