Module of the PA sensors

For the cyclic data traﬃc, DPT10 provides the following modules:

l AI (PA-OUT)

- PA-OUT value of the FB1 after scaling

l Temperature

- PA-OUT value of the FB2 after scaling

l Additional Cyclic Value

- Additional cyclical value (depending on the source)

l Free Place

- This module must be used if a value should not be used in the data telegram of the cyclical data

traﬃc (e.g. replacement of the temperature and Additional Cyclic Value)

Max. three modules can be active. By means of the conﬁguration software of the Proﬁbus master,

you can determine the conﬁguration of the cyclical data telegram with these modules. The procedure

depends on the respective conﬁguration software.

The modules are available in two versions:

l Short for Proﬁbus master supporting only one "Identiﬁer Format" byte, e.g. Allen Bradley

l Long for Proﬁbus master only supporting the "Identiﬁer Format" byte, e.g. Siemens S7-300/400

Examples of telegram conﬁguration

In the following you will see how the modules can be combined and how the appendant data telegram

is structured.

Example 1 (standard setting) with pressure value, temperature value and additional cyclical value:
