About SYSMAC NET Link/SYSMAC LINK Operations

This example is for a SYSMAC NET Link System. When 00000 is ON, the
following program transfers the content of IR 001 through IR 005 to LR 20
through LR 24 on node 10.

ER: The specified node number is greater than 126 in a SYSMAC NET
Link System or greater than 62 in a SYSMAC LINK System.
The received data overflows the data area boundaries.
Indirectly addressed DM word is non-existent. (Content of *DM word
is not BCD, or the DM area boundary has been exceeded.)
There is no SYSMAC NET Link/SYSMAC LINK Unit.
SEND(90) and RECV(98) are based on command/response processing. That
is, the transmission is not complete until the sending node receives and ac-
knowledges a response from the destination node. Note that the
SEND(90)/RECV(98) Enable Flag is not turned ON until the first END(01)
after the transmission is completed. Refer to the SYSMAC NET Link System
Manual or SYSMAC LINK System Manual for details about command/re-
sponse operations.
If multiple SEND(90)/RECV(98) operations are used, the following flags must
be used to ensure that any previous operation has completed before attempt-
ing further send/receive SEND(90)/RECV(98) operations

OFF during SEND(90)/RECV(98) execution (including
command response processing). Do not start a
SEND(90)/RECV(98) operation unless this flag is ON.
OFF following normal completion of SEND/RECV (i.e.,
after reception of response signal)
ON after an unsuccessful SEND(90)/RECV(98) attempt.
Error status is maintained until the next
SEND(90)/RECV(98) operation.
Error types:
