Selecting A Profibus Speed; Selecting Slave Parameters; Setting Module Hardware Options; Power Requirements - Control Technology 2500 Series Installation And Operation Manual

Selecting a Profibus Speed

The 2500-RBC supports Profibus speed from 9.6K bits/s to 12M bits/s. For more information on
selecting Profibus speed see Appendix A.

Selecting Slave Parameters

The 2500-RBC supports four parameterization options. These options are set using WorkShop, or
using the "properties" screen for the remote base in Com Profibus. For more information about these
settings, see "Setting Software Parameters in Com Profibus" in Section 2.4.

Setting Module Hardware Options

In addition to the Profibus address, the module includes a hardware setting for selecting the state of
the base discrete outputs in the event of a communications loss. The module can be configured to set
all outputs off, or to leave outputs at their last values.

2.2. Power Requirements

The CTI 2500-RBC module consumes 2.5 watts of +5 VDC power from the backplane. Before
installing the RBC, verify that your mounting base power budget can accommodate the required
power. A good tool for performing the verification is the CTI Replacement Guide and Power
Calculator, available from our website at
www.controltechnology.com
On the main page you will find a selection for the "Selection to CTI Replacement Calculator". This is
an excel file. Once downloaded you will open the file as a spread sheet. At the bottom of the spread
sheet you will find tabs for Instructions, Replacement Calculator and Power Calculator. Click on the
Power Calculator tab and follow the instructions.

2.3. Unpacking the Module

Open the shipping carton and remove the special anti-static bag that contains the module.
After discharging any static build-up, remove the module from the static bag. Do not discard the
static bag. Always use this bag for protection against static damage when the module is not inserted
into the I/O base.
CAUTION:
The components on the 2500-RBC module printed circuit card can be damaged by static
electricity discharge. To prevent this damage, the module is shipped in a special anti-static
bag. Static control precautions should be followed when removing the module from the bag
and when handling the printed circuit card during configuration.
