Table 29-5 shows the bit number of each parameter in instance 11 and an example packet returned from
a DECS-250. Reading a value of 0xA4 06 (1010 0100 0000 0110) for instance 11 indicates that contact
outputs 2, 5, 7, 9, and 10 are closed. The first byte is 1010 0100 and the second is 0000 0110.

Setup
The following steps are provided to assist in setting up the DECS-250 as a slave on a PROFIBUS
network. Please refer to the documentation included with your PLC configuration software for installation
and operation instructions.
1. Download the DECS-250 GSD file from the Basler website: www.basler.com
2. Using PLC configuration software, import the GSD file. This allows the DECS-250 to be included in
the bus configuration as a slave.
3. Assign a unique PROFIBUS address to the DECS-250. This allows the master to exchange data with
the DECS-250.
