Pro II-SENT-4-Out Rev. E
ADwin
You can change the SENT message via software: Signals 1/2 (fast
channel), serial message and reserved bits. The CRC checksums are
calculated automatically.
– FIFO mode: You fill a FIFO array with SENT messages (max. 400), the
module reads the FIFO array, and outputs the SENT messages consec-
utively. As soon as the FIFO runs empty the SENT channel is disabled.
You prepare the bit order of SENT messages on your own. This refers
in particular to the bits of the serial messages.
Output parameters
For the output of SENT messages the following parameters can be set for each
channel:
– Clock tick
– Fixed total length of the SENT message via pause pulse or variable total
length without pause puls
– Calculation algorithm "Legacy" or "Recommended" of the CRC check-
sum. The algorithmrefers to both the signals 1 and 2 as well as to the
serial message.
– Length of low level at the start of a pulse.
– Sending format of serial messages:
• short serial message format: 4-bit ID + 8-bit data value.
• enhanced serial message format:
8-bit ID + 12-bit data value or 4-bit ID + 16-bit data value.
You can query how much SENT messages have been sent on an output chan-
nel.
Digital channels
There are 4 digital inputs (DIGIN 16…19) and 4 digital outputs (DIGOUT 24 …
27) on the 37-pin D-Sub connector; pin assignment see fig. 173.
The channel numbers 0…15, 20…23, and 28…31 are not available.
Please note: While using digital channels, no instructions for input fifo or output
fifo are allowed. Otherwise the SENT interface will work incorrectly.
Modul revision
Differences between revisions are described below. The revision number is
located on the front panel.
Different revision characters mean different module characteristics and are
documented separately. A counter number is added for internal purpose.
The interface version is not visible from outside but can be queried by software
with
