Response Block
Parameters
Status flags (response): This byte contains flags providing information on
overall data link status, as follows:
Present and Max. refresh time (response): The present and maximum data
link refresh times in 4-digit hexadecimal in increments of 1 ms. The range is 0005
to 00FF (5 to 255 ms, in decimal).
Data link status (response): Four bits are allocated to each node number to
provide information on the status of the data links, as shown below. The function
of each of the 4 bits is shown in the diagram following the table.
Performs an internode echo test with the indicated node.
Test data (command and response): Up to 512 byte of test data can be
included in the command. This data is transmitted to the indicated node and
returned unchanged if communications are normal. If the data returned in the
