Chapt.1 System Configuration
Operation:
When the instruction input is ON, one set of message which is stored in the
source table (from start character to the trailing code) is transmitted through
the link port. The execution status is stored in the status flag.
The instruction input must be kept ON until the transmitting operation is
complete.
Example:
Source designation Transfer size Destination designation
D0010 HOO H04 D0012 00012 D0015 HOO H30
D0011 00500 D0013 Execution status D0016 00000
D0500 (CPU register) Link port
When R0001 is ON, one set of message (ended by the trailing code) stored in
the range of D0500 to D0511 (12 words) is transmitted through the link port.
Execution status: HOOOO ... Normal complete
H0001 ... During transmitting the message
H0002 ... Communication busy (other receiving/transmitting
routine is executing)
H0003 ... During the reset operation
H0004 ... Send time-out (from start character to the trailing code)
H0005 ... Send message length error (no trailing code in the source
table)
Baudrate Time-out setting
300, 600, 1200 bps 30 seconds
2400 bps 15 seconds
4800 bps 7 seconds
9600 bps 3 seconds
19200 bps 1.5 seconds
Remarks:
The instruction error flag (S0051) comes ON in the following cases, (no
operation)
• The leading address for the link port designation is other than 0.
• Transfer size is out of the range of 1 to 256.
• Mode setting of the link port is not the free ASCII mode.
• This instruction is programmed in the sub-program #1.
