DAP (Device Access Point) of the Coupler Box
The device model chosen for PROFINET is the distributed periphery, which is familiar from PROFIBUS DP.
The slots of the modular devices are represented via slots and sub slots.
Slot 0 is designated as device access point (DAP). This is where writing to the module takes place.
The current value of the control bit is returned in the status bits. Also, in bits 8 - 15 an IP-Link counter or the current IP-Link cycle time is displayed, depending on "S" in control bit 6.
