4. Indicates a Unit as shown in the following table.
PC
SYSMAC NET Link, SYSMAC LINK,
or Controller Link Unit
SYSMAC BUS/2 Master, BASIC Unit,
or Personal Computer Unit
SYSMAC BUS/2 Group 2 Slave
5. The destination node number can have the following values:
System
SYSMAC NET Link System
SYSMAC LINK System
Controller Link System
Set a value of $00 to transmit within the local PC (to/from CPU Bus Units).
Set a value of $FF to broadcast to all nodes in the network.
6. Designates the length of time that the PC retries transmission when bit 15 of
C+3 is OFF and no response is received. The default value is $0000, which
indicates 2 seconds.
7. Transmissions cannot be sent to the PC executing CMND(194) (i.e., the
Unit cannot be specified as $00 and the destination node number set to
$00).
C through C+5 must be within the values specified below. To be able use of
CMND(194), the PC must have a SYSMAC NET Link, SYSMAC LINK Unit, Con-
troller Link Unit, or SYSMAC BUS/2 Remote I/O Master Unit mounted.
Do not change the control data during a transmission (i.e., while the correspond-
ing Port Enabled Flag in A502 is OFF).
The Execute Error Flag for the designated port will be turned ON if no response
is received in the response monitoring time (C+5), the amount of command data
transmitted exceeds the maximum for the system, or the response data exceeds
the number of bytes specified in C+1.
The amount of response data can be less than the "number of bytes to receive"
in C+1 without causing an error, but the amount of the command data must
agree with the "number of bytes to send" in C or a command length error will oc-
cur. Be sure that the command data and response data do not go over the end of
a data area.
CMND(194) only starts the transmission of command data. Verify that the trans-
mission has been completed with the Network Status Flags in A502. If data is
changed before transmission is completed, the data might be transmitted while
data is being changed.
Note Refer to page 101 for general precautions on operand data areas.
Content of *DM word is not BCD when set for BCD.
