Object 0X2200 Activation - Leuze electronic BCL 338i Original Operating Instructions

BCL 338i in the EtherCAT system
11.4.4.5 Object 0x2200
The object 0x2200
for the control of the result output. It is possible to select between standard data output oper-
ation and handshake operation.
In handshake operation, the control must acknowledge the data reception via the ACK bit
before the new data is written into the input area.
After acknowledging the last result, the input data is reset (filled with zeros).

Note!
This setting can only be performed via CoE (startup parameter) in PreOp ESM state.
If multiple results are produced within an activation, the input data of the result data objects
is overwritten with the last generated result while in standard data output operation (without
ACK). It is possible - dependent on the cycle time - that only the last result is visible on the
bus.
In this case, handshake operation (with ACK) must be used. There is otherwise a risk
of data loss.
Multiple individual results can be produced within an activation, for example, if the bar code
reader detects multiple codes within an activation and interprets the result as valid.
