SYSTEM DESCRIPTION
In order to adapt the 16-channel digital modules to the data format of the control there is the opportunity to
switch the byte position for channel 1-8 and 9-16. By default, channels 9-16 (slot 3.x and 4.x) are on byte n
and channels 1-8 (slot 1.x and 2.x) are on byte n+1.
The format is switched with bit 4 in the control byte (parameter telegram, byte 11, see Parameter telegram
section ). Channels 1-8 (slot 1.x and 2.x) are then on byte n and channels 9-16 (slot 3.x and 4.x) on byte
n+1.
Default (Bit 4=0)
Switched (Bit 4=1)
In order to adapt the 32-channel digital modules to the data format of the control there are opportunities to
switch the byte position of channel groups 1-8, 9-16, 17-24 and 25-32. By default, channel 1-8 (slot 1.x) are
on byte n+3 and channels 9-16 (slot 2.x) on byte n+2, channels 17-24 (slot 3.x) on byte n+1 and channels
25-32 (slot 4.x) on byte n.
If bit 6 is set in the control byte (parameter telegram, byte 11, see Parameter telegram section ), switch the
format. Channels 1-8 (slot 1.x) are then on byte n and channels 9-16 (slot 2.x) on byte n+1, channels 17-24
(slot 3.x) on byte n+2 and channels 25-32 (plug 4.x) on byte n+3.
