Redundancy Link Interface
When using two LD 810HSE Ex Linking Devices as a redundant set, the
redundancy link interfaces (RDL) of both Linking Devices (primary and second-
ary) must be connected by a cable, thus forming a “redundancy link”. If the
redundancy link is not installed during start-up (power-on), the LD 810HSE Ex
will operate in non-redundant mode.
The interface is not galvanically isolated. Thus make sure that there
is no potential difference between the two connected devices.
The maximum cable length is 0.5 m according to EMC requirements. The pin
assignment is as follows:
Pin
Signal
Description
4
GND
Ground
5
TX
Transmits data to redundant device.
6
RX
Receives data from redundant device.
