Earthing
The controller is grounded by the spring contacts on the underside of the product
by snapping it onto the grounded DIN-rail (see figure in “Mounting” > “Insert
Controller”).
7.2
Connecting Devices
The
ETHERNET interfaces
are used to connect to a LAN or to the Internet for
communication with the controller. Crossover or patch cables category 5e can be
used.
Do not use USB devices connected to earth!
USB interface shielding is not earthed directly, rather via interference-
suppression capacitor. Only keyboards, mice and USB memory sticks may be
connected. Do not connect devices that are earthed, e.g., printers, because they
bridge the interference-suppression capacitors and thus interference immunity is
reduced.
Insert
microSD
memory cards as far into the slot until they click into place. The
slot can be sealed to protect the card.
To remove, press the card further down until the lock releases. The card can then
be removed.
The USB service interface is designed as a USB-C socket. The interface
supports USB Specification 2.0.
The controller appears on the host device (PC) as a peripheral device in device
mode.
The controller uses the fixed IP address 192.168.42.42 to communicate with a
PC.
For more information about the interfaces, see section “Device Description” >
“Connectors” and “Technical Data”.
