4. IRC test 4, 5 (Data transmission test)
This test is intended to perform data transmission test in an actually
configured system. The system to be tested is composed of one set
of master machine (set by JOB #604) and max. 15 sets of slave
machines (set by JOB #603).
Note for starting the test:
•
When testing a set in which the IRC setting has been already
made, be sure to cancel the inline setting in the following proce-
dure before performing this test.
To cancel the inline setting:
SRV mode: 902
•
When testing an already configured system, cancel the inline set-
ting of the set which are not to be tested in the above procedure or
disconnect their signal lines. (Disconnect the inner cable and the
joint connector.) If the test is executed without cancelling the inline
setting of a set which is not to be tested, the data in the set may be
destroyed.
•
Cancel the inline setting of all the sets in the system before per-
forming the transmission test (JOB #603, JOB #604) setting. Per-
form the satellite machine setting (JOB #603) before performing
the master machine setting (JOB #604).
Note for terminating the test:
•
After terminating the test of all the sets used in the test (by the
program resetting), perform setting of each set.
•
For the set whose inline setting was cancelled before the test
because its IRC setting had been made, perform the inline setting
in the following procedure. This test will not affect the other set-
tings.
To set the inline setting YES:
SRV mode: 902
1 Satellite machine setting (JOB #603)
