7.3 Modules
There are nine modules available for configuring the PUC 28 as a Profibus slave (combining
the input and output data). Any combination of modules is permitted. The only thing to keep in
mind is that module 33 (“command byte”) must be a component of the configuration.
No. Conf. Description
1
0xD0 1 word input; consistent over the entire length; signed int
“Measured value, internal pressure” (in 1/10 Pa)
2
0xD0 1 word input; consistent over the entire length; signed int
“Measured value, temp/pressure IN-1” (in 1/10°C or 1/10 Pa)
3
0xD0 1 word input; consistent over the entire length; signed int
“Measured value, humidity/pressure IN-2” (in 1/10%rH or 1/10 Pa)
4
0x10
1 byte input; consistent over byte/word
“Warning States”
Bit = 1 → outside the limits
Bit = 0 → within the limits
If a measured value is outside the limits, it may also be outside the valid
measurement range. The transferred value could therefore be invalid.
Bit
Description
0
Value lower
than the low
limit
IN 2
1
IN 1
2
Internal pressure (if at least one bit =1)

IN 2
5
IN 1
6
Internal pressure (if at least one bit =1)
7
5
0x10
1 byte input; consistent over byte/word
“Status”
Byte.0 = 0 → ZPCC is not being performed at this time
Byte.0 = 1 → ZPCC is being performed at this time
