Data transfer was completed successfully.
SEND(90)/RECV(98) instruction operands are not within specified ranges.
The System was reset during execution of the instruction or the destination
node is not in the System.
The destination node is busy and cannot receive the transfer.
The line server token was not received.
An error occurred in the transmission loop.
Destination node does not exist or response was not received within the

Incorrect response format.
SYSMAC LINK/SYSMAC NET Link Data link status is output to SR 238
through SR 241 for the operating level 0 data link, and to SR 242 through SR
245 for the operating level 1 data link in the SYSMAC NET Link or SYSMAC
LINK System.
The meaning of each bit in these areas differs depending on whether the
data link is in a SYSMAC LINK System or SYSMAC NET Link System, as
shown below.

When the PC belongs to a PC Link System, words 247 through 250 are used
to monitor the operating status of all PC Link Units connected to the PC Link
System. This includes a maximum of 32 PC Link Units. If the PC is in a Multi-
level PC Link System, half of the PC Link Units will be in a PC Link Subsys-
