6. Destination unit address: Set the destination unit address of the Host Link
Unit that is connected to the host computer.
7. Response designation: Usually set this bit to 0 (OFF). If no response is re-
quired, set this bit to 1 (ON).
8. Communications port no.: Set the port number of the PC sending the
CMND(194) instruction.
9. No. of retries: Set the upper limit of the number of retries for obtaining a re-
sponse after the CMND(194) instruction is sent.
10. Response monitor time: Set the response monitor time, during which the
Host Link Unit waits for the response.
Note If the response data returned is longer than the designated length of the recep-
tion data, the response data will not be stored. If the response data returned is
shorter than the length of the reception data bytes set, the response data will be
stored and the unused area will remain as it is.
The setting range of each control data item is as follows:
Item Range
No. of transmission data
bytes
0002 to 021E (2 to 542 bytes)
No. of reception data
bytes
0002 to 021E (2 to 542 bytes)
Host Link Unit
communications port no.
00 to 01: Communications port 1
01: Communications port 2
Destination network
address
00: Local network
01 to 7F: Network address (1 to 127)
Destination node number 00: Within local PC
01 to 7E: Node number (1 to 126) (SYSMAC NET)
01 to 3E: Node number (1 to 62) (SYSMAC LINK)
Destination unit address 10 to 1F:Host Link Unit (unit numbers 0 to 15)
Response designation 0 (OFF): Response required
1 (ON): No response required
Communications port no. 0 to 7 (0 to 7)
No. of retries 0 to F (0 to 15)
Response monitor time 0000: Default (2 s)
0001 to FFFF (0.1 to 6,553.5 s with 0.1-s increments)
Note In order to execute the CMND(194) instruction properly, it is necessary to pre-
pare a program on the host computer so that the host computer will execute the
command that the host computer has received and transmit data.
4-5 Communications Timing
The transmission timing of commands sent to the host computer is explained
below. The transmission timing varies with the communications system (i.e., the
transmission timing in full-duplex communications (such as Xon/Xoff control)
and that in half-duplex communications are different). Full-duplex or half-duplex
communications is set in the CPU Bus Unit System Setup.
