3. Using drag-and-drop, move the associated CiR object from the hardware catalog onto the
master system. The CiR object then appears in the upper part of the station window as a
placeholder slave. The CiR object has the following default values:
– Number of guaranteed additional slaves: 15 on DP master system, 6 on PA master
– Maximum number of additional slaves: 45 DP slaves, 36 PA slaves
– Number of input bytes: 1220 for a DP master system, 80 for a PA master system
– Number of output bytes: 1220 for a DP master system, 80 for a PA master system
4. The default settings of the CiR objects are the same for all CPUs. For this reason, after
definition of a CiR object, you should check whether the CiR synchronization time of the
associated master system specified in the properties window of the CiR object is
compatible with the CiR synchronization time of the CPU.
5. If you want to change the number of additional slaves and/or the number of input/output
bytes, proceed as follows:
Open the properties window of the CiR object (double-click the CiR object or select CiR
object, right-click and select "Object properties ..." or select CiR object and "Edit > Object
properties ...").
You can change the guaranteed number of additional slaves. The lower part of the station
window displays the resulting bus parameters: Target Rotation Time, Typical Target
Rotation Time and watchdog time.
You can also change the number of input bytes and output bytes. To do so, select the
"Advanced settings" check box.
Adding a CiR module in a modular slave of type ET 200M / ET 200iSP
For a modular slave, proceed as follows:
1. Select the relevant slave in the upper part of the station window.
2. Open the "Hardware catalog" window.
