5-2-6 Table Registration Function (1 | REGS)
Functionality to registers the configuration of the connected SmartSlice I/O Units in a table within the
Communication Unit. This table can then be used to compare the registered table with the information
of the Master.
 ON (during power up) = Compare
The registered I/O table will be compared automatically with the actual configuration each time the
power of the EtherCAT Communication Unit is turned ON.
The red blinking TS LED indicates a verification error. A verification error will occur if a registered I/O
Unit is not available or an unregistered I/O Unit is detected.
The verification error will prevent the Communication Unit to change from init to pre-operational.
For communication state details refer to "2-5 Communication State Transitions" in page 2 - 7.
Pin 1 ON when power
was turned ON.
Registration table
Reference
A mismatch (verification error) with the registered table is indicated at the EtherCAT
Communication Unit's TS indicator (flashing red).

Unit
The actual configuration is compared to the registered table.
Units that do not match the registered table do not participate
in I/O communications. I/O communications start with the other
I/O Units.

There are the same number of
Units, but the I/O data size does
not match, so a verification error
occurs and this I/O Unit does not
participate in communications.
