7.4 Communication interfaces
7.4.1 Fiber optic connections X10 and X11
The FO cables transmit the process data between the device and the connected iba
systems. The 32Mbit Flex transfer protocol also allows configuration data to be trans-
ferred via FO cable.
Connection Description
X10 output (TX) FO send interface
X11 input (RX) FO receive interface
Maximum distance of fiber optic connections
The maximum distance of fiber optic connections between 2 devices depends on various
influencing factors. This includes, for example, the specification of the fiber (e.g.
50/125
μm, 62.5/125 μm, etc.), or the attenuation of other components in the fiber optic
cable plant such as couplers or patch panels.
However, the maximum distance can be estimated on the basis of the output power of
the transmitting interface (TX) or the sensitivity of the receiving interface (RX). A model
calculation can be found in chapter 11.7.
The specification of the transmitter's output power and the receiver's sensitivity of the
fiber optic components installed in the device can be found in chapter "Technical data"
11.2 under "ibaNet interface".
7.4.2 Network interface X22
Ethernet interface 10/100 Mbit/s, no function.
7.5 Digital inputs X5
7.5.1 Connection diagram / pin assignment
You can connect eight input signals (0…7) here, each bipolar and electrically isolated.
Each channel is connected by means of two-wire connection. Due to the reverse polarity
protection, the measuring signal is indicated logically correct even if the connection is
polarity-reversed.
