Section 4-4
Specify, in hexadecimal, the number of bytes of test data to be sent between
nodes.
0000 (Hex): 1,996 bytes
0001 to 07CC (Hex): 1 to 1,996 bytes
Internode Test Response Monitoring Time (CPU Unit to Ethernet Unit)
Specify, in hexadecimal, the amount of time to wait for the internode test
response.
0000 (Hex): 2 seconds
0001 to FFFF (Hex): 0.01 to 655.35 seconds
Internode Test Status (Ethernet Unit to CPU Unit)
Internode test results are reflected here. (The bits all turn back OFF when the
internode test is started.)
Bits 0 to 5 turn ON when their applicable error occurs.
The error code for the error that occurred is stored in bits 13 to 15. The mean-
ings of the error codes are shown in the following table.
Note When a routing table error or a sent parameter error occurs, the number of
internode test runs is not incremented.
Number of Internode Test Runs (Ethernet Unit to CPU Unit)
Internode tests are executed repeatedly as long as the Internode Test Start
Switch, one of the Unit Control Switches in the CIO area, remains ON.
In this word, specify in hexadecimal the number of times that the internode
test is actually to be executed.
0000 to FFFF (Hex): 0 to 65,535 times
