PLR605X ProLink5 Display Test Patterns

To start the ProLink5 test pattern mode, loop the
fiber cable from Port A to Port B on the ProLink6
ports, disconnect power, and reconnect power. The
7-segment display shows t p t to indicate it is in this mode.
Refer to Figure 26.
Test patterns are sent out to the ProLink5 display elements
in a repeating cycle as long as the PLR is powered on
and the fiber loopback connection remains in place.
Test patterns are listed in the following table in the order they are displayed.
Test Pattern Color
Solid red
Solid green
Solid blue
Solid white
Solid amber*
Solid magenta*
PLC51XX walking cyan pattern**
Blank
*All ProLink5 devices have a built-in redundancy feature, so the solid amber and solid
magenta test patterns are used to detect breaks in redundant links. Solid amber is
transmitted out of PLR Port A only and solid magenta is transmitted out of PLR Port B only.
**This sequence is shown only on PLC51XX ProLink5 nodes. The first PLC that is connected
to ProLink5 Port A will show cyan, followed by the next PLC, and so on. The pattern will
move to the next PLC at one-second intervals, up to 16 PLCs. This pattern is supported
with PLR release 2013-12 RP00 and later.
To exit the ProLink5 test pattern mode, disconnect the fiber loopback connection.
