3.8 Prerequisites for Certification
3.8.1 PROFINET
IO
Certification for IRT and SYNC0 Signal
3.8.1.1
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
3.8.1.2
Using the SYNC0 Signal at the Host System
Only valid for
PC Cards Mini PCI Express CIFX 90E-XX\MR\F or
PC Cards Mini PCI Express CIFX 90E-XX\MR\ET\F
If you forward the SYNC0 signal of your PC card cifX Mini PCI Express to
the Mini 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 Mini PCI
Express bus X2 of the PC card cifX Mini PCI Express at the host system
and provide it at the host system via a well accessible 2-pin connector.
The PC card cifX Mini PCI Express provides the SYNC0 signal
SYNC0
.
The SYNC0 signal is provided at pin 46 of the Mini PCI Express bus X2.
For the pin assignment of the Mini PCI Express bus X2, refer to section
Assignment for Mini PCI Express Bus / SYNC Connector (Bootstart), X1/X2
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.
