3.10 Prerequisites for Certification
3.10.1 PROFINET
IO
Certification for IRT and SYNC0 Signal
3.10.1.1
Providing SYNC0 Signal at SYNC Connector of the PC Card cifX
Note:
A PROFINET IO certification for PROFINET IRT requires
(mandatory) that your PC card cifX offers the synchronization signal
(SYNC0), in order to allow e. g. connecting an oscilloscope. Therefore the
SYNC connector of your PC card cifX must be accessible.
Information about where the SYNC connector is placed on your PC card
cifX, you can find in the chapter
3.10.1.2
Using the SYNC0 Signal at the Host System
Only valid for PC Card CIFX 100EH-RE\CUBE:
If you forward the SYNC0 signal of your PC card cifX 100 EH-RE\CUBE to
the PCI Express bus X2, you must adhere to the following design
specification:
Note:
A PROFINET IO certification for PROFINET IRT requires
(mandatory) that the host system offers a connector for the
synchronization signal (SYNC0), in order to allow e. g. connecting an
oscilloscope.
For this purpose you must use the SYNC0 signal and mass of the PCI
Express bus X2 of the PC card cifX 100EH-RE\CUBE at the host system
and provide it at the host system via a well accessible 2-pin connector.
The PC card CIFX 100 EH-RE\CUBE provides the SYNC0 signal
SYNC0
. If
at the SYNC connector (J1) the jumper is set on Pin1-Pin2, the SYNC0
signal is provided at pin B24 of the PCI Express bus X2. For further details
on the pin assignment of the SYNC connector and on how to set the
jumpers, refer to section
Pin Assignment SYNC Connector, J1 (CIFX
on page 112. For the pin assignment of the PCI Express bus X2,
refer to section
Pin Assignment for PCI Express Bus CIFX 100EH-
The SYNC0 signal has LVTTL level (3.3 V). A maximum load of 6 mA must
not be exceeded.
You should keep the cable length for the sync signals below 50 mm and
take into account EMC aspects.
