Siemens SIDOOR ATD4 W Series - Cyclic Process Values Via Fieldbus; Parameter Checksum (as of V1.12)

This way the accumulation of contamination does not result in an "escape" of the door from the
closed position.
4.2.10 Cyclic process values via 󹪝eldbus
As of 󹪝rmware version V1.09, cyclic process values can be transferred to a higher-level controller
using PROFIBUS or PROFINET by means of the technology status words TZW3, TZW4 and TZW5.
The content of these technology status words can be con󹪝gured with the parameters p4700,
p4701 and p4702. The following process values are available:
• Digital inputs, D-IN
• Digital outputs, D-OUT
• Button
• Door position in mm
• Door setpoint speed in mm/s
• Door actual speed in mm/s
• Motor current in mA
• Motor current limitation in mA
• Voltage of the motor output stage in V
• Remaining power capacity of the braking resistor in J
• Currently displayed operating status (as of V1.12)
The default values of parameters p4700, p4701, p4702 correspond to the settings for TZW3,
TZW4, TZW5 in 󹪝rmware versions prior to V1.09.
To use the technology status words. see also Appendix TZW3, TZW4, TZW5 - Technology status
words 3, 4, 5 (Page 327).
4.2.11 Parameter checksum (as of V1.12)
Description of function
Firmware version V1.12 or higher:
To ensure that certain parameter ranges have not been changed, it is possible to read out a
checksum:
• r200: Checksum for the default parameters
• r201: Checksum for the learn run/basic parameters (p2101 to p2111)
As soon as a parameter of the respective range changes, its checksum is recalculated.
A retentive change counter (r202) is incremented by one every time a parameter from the
default range is changed. After resetting the parameters to the factory setting with p91, the
change counter is set to zero.
