4. Turn OFF the Internode Test Start Switch allocated to the Ethernet 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 during the
test, however, the new parameters will not be used until the Internode Test
Start Switch is turned OFF and then back ON.
2. Line traffic on the Ethernet network will increase during the test, possibly af-
fecting system performance.
Before starting the test, set the following parameters in the software switches in
the words in the DM area allocated to the Ethernet Unit. The test parameters
become effective immediately after they are set. It is not necessary to reboot or
restart the PC.
The software switches are stored at offsets from the first word calculated with the
formula: first word = D03000 + (100 x unit number).
Offset
+0 Bits 8 to 15:
Remote network address
+1 Number of send bytes
+2 Response monitor time
The parameter setting ranges are given in the following table.
Parameter
Remote network address
Remote node number
Number of send bytes
Response monitor time
(Unit: 10 ms)
Note 1. The following limits apply to the number of bytes sent when running the test
through a SYSMAC NET or SYSMAC LINK network:
SYSMAC NET: 1,986 bytes
SYSMAC LINK: 512 bytes
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
monitor time.
Bit 01 of the first word in the words allocated to the Ethernet Unit in the CPU Bus
Unit Area is used as the Internode Test Start Switch. 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 Switch is calculated by the following for-
mula:
Word = 1500 + (25 x unit number)
