Configuration
For efficient communication between DP master (higher-level controller (PLC)) and DP slave, the
DP master has to know how many bytes it sends to the DP slave, and how many bytes it receives
from the DP slave. The values for the outputs and inputs are specified in the configuration.
The configuration of a DP slave is specified in the GSD file. Before the DP slave can exchange user
data with a DP master, the valid configuration must be transferred from the DP master to the DP
slave and confirmed.
Each DP slave has slots . Each slot can be a module. The SIDOOR ATD420W controller is designed
as a modular DP slave and has exactly one slot. The standard module is available for this slot.
The configuration for the standard module consists of 22-byte inputs and outputs, and a
manufacturer-specific byte.
The 22-byte inputs and outputs form the process image which, as standard, consists of 7 words
for the process data (PZD) and 4 words for the parameter identifier value (PKW). The reserved
manufacturer-specific byte is currently used only as a placeholder.

Cycle time (high byte)
Cycle time (low byte)
The cycle time is given in [ms]. The cycle time de‐
fines the minimum time intervals at which the slave
is queried by the master.
Time range = 10 to 60000 ms.
Factory setting = 100 ms (0x0014)
