4.6 Programming the Ident profile
The following diagram illustrates the running of the Ident profile over time. A command is
always started on the positive edge of "EXECUTE", "INIT" or "SRESET".

Parameter assignment for starting up and restarting

The communications module and the reader are restarted by setting the "INIT"
parameter. With the parameter, the CM or the reader and the Ident profile are
reassigned parameters and synchronized.
An "INIT" is necessary after
• Switching on or restarting the controller
• Switching on the power supply of the CM/reader
• Plugging the reader into the CM
• Interruption in Ethernet/IP communication
• An error message by the "STATUS" parameter

The function/instruction is started by setting EXECUTE (EXECUTE = 1). If the job was
completed successfully (DONE = 1), you need to reset EXECUTE. DONE is reset at the
same time.
EXECUTE is set for only one cycle. As soon as BUSY is set (and DONE is reset), you can
reset EXECUTE again. If the job was completed successfully, DONE is set for one cycle.
Handling as in Case 1, however with error output. As soon as ERROR is set, the precise
error code is available in the STATUS output. ERROR and STATUS retain their value as
long as EXECUTE is set.
