Check For State Of Connection (Line Test) - Mitsubishi Electric AJ65BTS-RPH User Manual

(4) Connect the included 110Ω terminating resistor to the module
located at the end of a segment when the branch line side of the
AJ65BTS-RPH is connected to the segment.
For the connection of terminal resistor, refer to the manual of the
module connected.
(5) For the branch line side of the AJ65BTS-RPH, use the incorporated
110Ω terminating resistor.
In addition, connect the shielding wire of the CC-Link dedicated
cable to "SLD" of each module, and ground both ends via "FG".
Note that SLD and FG are connected to each other in the module.

4.5 Check for state of connection (line test)

Connect all modules including the AJ65BTS-RPH module through the
CC-Link dedicated cable. Then, check that the CC-Link system is in the
state capable of performing a data link normally.
Because whether or not a master station can establish a data link with a
particular slave station can be checked by the connection status check
(circuit test), an error module can be identified.
For the connection status check (circuit test), perform the circuit test 1 of
the master module. If an error is detected, perform the circuit test 2 of
the master module.
For the details of circuit tests 1 and 2, refer to the user's manual of the
master module used.
Perform the test following the steps shown below.
POINT
Perform the circuit test 2 of the master module by selecting the target
stations as described in (1) to (3) below.
(1) In the segment including the master module, select slave stations
in order from the nearest to the master module to the farthest.
(2) In the segment (1st stage), select slave stations in order from the
nearest to the AJ65BTS-RPH to the farthest.
(3) In the segment (2nd stage), select slave stations in order from the
nearest to the AJ65BTS-RPH to the farthest.
