4.4. Connection of s88 feedback modules
Info
The mc² regularly initiates read-in cycles in which the levels of all registers in the clock are
"passed through" from one register to the next to the central unit according to the bucket
brigade memory principle. Like most modern central units, the mc² compares the read-in data
with those of the previous read-in cycle and evaluates only the changed data or passes only
the changes on to the control software.
Connection: RJ45 (according to s88-N)
Connection options
You can connect a total of up to 52 s88 feedbacks or s88-compatible modules (with max. 832
contacts).
!
Notice:
Do not plug s88 bus cables into the BiDiB connector! This can cause severe damage to the
mc².
Note:
!
There are s88 feedback modules available with RJ45 connections where the contact
assignments do not correspond to the s88-N standard. These are not suitable for connection
to the mc². Damage to the mc² and/or the connected modules may occur during
commissioning!
Configuration
Before starting operation, you must enter the number of connected s88 feedback modules.
