General Information
•
To reduce the risk of losing information stored in files on the µSD-card, especially when writing
to the card during a power failure event, consider the use of an external UPS (uninterruptable
power supply). Alternatively, mount the µSD card as read-only, in combination with a RAM-file
system overlay.

CODESYS Control for Raspberry Pi SL Information
NOTICE
Without further agreements, Janz Tec AG does not provide support for configuring and
running CODESYS Control for Raspberry PI SL on the emPC-A/RPI3!
CODESYS control runtime system is a soft PLC created by the company 3S-Smart Software Solutions
GmbH and is available for Raspberry Pi based devices. Using this IEC 61131-3 programming system
in combination with our emPC-A/RPI3 system is ideal for testing and educational applications,
because the control can make use of the additional interfaces the emPC-A/RPI3 offers (digital IO,
CAN, RTC and RS232/RS485).

NOTICE
Always consult the official “CODESYS Control for Raspberry Pi SL” documentation,
product description, features and licensing terms.
The following summary of features is only for your information and might not be accurate.
Even with the standard Raspbian operating system without any modifications, the CODESYS Control
for Raspberry Pi SL can control all digital IOs on the emPC-A/RPI3 by using the GPIO device already
included in the CODESYS device repository. (Red and green LED also controllable by this GPIO
device). The serial console (RS232) is also support by default. *2
When the optionally available emPC-A/RPI3 driver package is installed, the CODESYS control can
also access the CAN port for CAN/CANopen as well as the serial console (RS232) and the
RS232/RS485 ports for serial and Modbus RTU communications. The RTC support is especially
useful when you do not have a network time server connected, but you want to use date and time in
e.g. log files.
