Product overview
2.1 Properties
Properties
The technology module SIMATIC ET 200SP TM ECC PL ST serves to control and monitor
the conduction current charging of electric vehicles in accordance with the standard DIN
SPEC 70121, Charging mode 4. To this purpose it provides a charging outlet.
The module generates and monitors a CP signal (Control Pilot Signal) according to
IEC 61851-1.
Communication between the vehicle and the charging station takes place based on
"Powerline Green Phy" (HPGP). This overlays the "Control Pilot Signal". In accordance with
the standard the "duty cycle" of the PWM signal is set fixed to 5%.
Its TRIP function (Page 17) is intended to ensure that the charging voltage (dangerous to
touch) is only applied to the charging cable when:
● The charging cable is connected correctly
● The vehicle is ready to be charged or is charging (Charging state C or D)
In addition this TRIP function ensures that voltages dangerous to touch on the charging
cable (caused for example by the charging connector) are switched off.
In addition the proximity contact PP (Plug Present) is monitored by means of the PP function
(Page 18). As soon as the button is pressed at the charging plug or the plug is removed from
the vehicle, the associated DQ P is set to "False". This means that the Open Collector output
is high-impedance (see "Example circuitry of the switching contacts (Page 30)" in the section
"Switching contact DQ T and DQ P").
You have to use the function block DIN_70121 (Page 39) to integrate the SIMATIC ET
200SP TM ECC PL ST technology module into the TIA environment. The function block
monitors the respective breakers, initiates the cable check and makes the corresponding
current and voltage specifications of the vehicle available to the associated frequency
converters.
If an insulation monitor exists, it is evaluated (warning/fault). If a fault occurs at the insulation
monitor, the frequency converter is shut down in a controlled manner - in as far as possible.
The CP voltage level changes to -12V.
If an emergency shutdown is required, the frequency converter is shut down in a controlled
manner - in as far as possible. The CP voltage level changes to -12V.
