Internode Test Section 9-3

3. If desired, the test parameters can be changed while the internode test is
actually running. Use the same procedure as used in step 1.
4. Turn OFF the Internode Test Start Bit allocated to the FL-net Unit in the
CPU Bus Unit Area to stop the test.
Note 1. The test parameters are effected as soon as they are set or changed. It is
not necessary to reboot or restart. If the test parameters are changed dur-
ing the test, however, the new parameters will not be used until the Intern-
ode Test Start Bit is turned OFF and then back ON.
2. Line traffic on the Ethernet network will increase during the test, possibly
affecting system performance.
Setting the Test Parameters
Before starting the test, set the following parameters in the CPU Bus Unit
Area (in the CIO Area) of the PLC. The test parameters become effective
immediately after they are set. It is not necessary to reboot or restart the PLC.
Configuration of the test
parameters The software switches are stored at offsets from the first word calculated with
the formula: first word = 1500 + (25
×
unit offset)
Setting Range The parameter setting ranges are given in the following table.
Note 1. The test cannot run across a FINS network.
2. Broadcast transmissions (target node address = FF) cannot be used for
the internode test.
3. A timeout error will occur if no response is received within the set response
monitoring time.
Starting and Stopping the Internode Test
Bit 01 of the first word in the words allocated to the FL-net Unit in the CPU
Bus Unit Area is used as the Internode Test Start Bit. Turn ON bit 01 to start
the internode test and turn bit 01 OFF to stop the internode test. The address
of the word containing the Internode Test Start Bit is calculated by the follow-
ing formula:
Word = 1500 + (25
×
unit number)
The internode test run status can be confirmed using the TS indicator on the
Unit’s front panel.
