PLC Network Instructions Section 6-2
Unit Address has been set to FE, commands will be sent to the SYSMAC
LINK Unit, Controller Link Unit, or Ethernet Unit with the relevant destina-
tion node address.
6. Response Bit
Usually set this bit to OFF (0: required). If no response is required, set the
bit to ON (1: Not required).
7. Communications Port Number
Set the communications port number that the CMND(490) instruction will
be sent to.
8. Number of Retries
Set the number of retries for unsuccessful transmissions. You can set the
number between 1 to 15. If 15 has been set, for example, the CMND(490)
instructions will be re-transmitted up to 15 times when the PLC does not
receive a response from the destination node.
9. Response Monitor Time (Unit: 0.1 S)
Designates the length of time that the PLC retries transmission when bit
15 of C+3 is OFF and no response is received. The default value is $0000,
which indicates 2 seconds.
Note If more than the Number of Bytes to Receive is received, no response will be
stored. If fewer bytes are received, the response data will be stored and the
unused memory area of the PLC will remain unchanged.
Range of Control Data The permissible ranges of control data are as follows:
Note (1) FE, or unit 10 (FE can be set when the destination is a SYS-
MAC NET Link, SYSMAC LINK Unit, Controller Link Unit, or Ethernet
Unit.
Destination Address (hexadecimal)
PLC (CPU) 00
NSB (computer) 01 (user application)
CPU Bus Unit 10 to 1F: Unit Number 0 to F (0 to15)
Inner Board E1
Unit connected with the network FE
Item Value
Number of bytes to send 0002 to 021E (2 to 542 bytes)
Number of bytes to receive 0002 to 021E (2 to 542 bytes)
Destination network address 00: Local network
01 to 7F: Destination network address
Destination node address 00: Transmission within local PLC
01 to 3E: Destination node address (1 to 62) (SYSMAC LINK)
01 to 20: Destination node address (1 to 32) (Controller Link)
01 to 7E: Destination node address (1 to 126) (Ethernet, SYSMAC NET)
FF:
Broadcasting
Destination unit address 00: PLC (CPU Unit)
01: Computer (NSB), user application 1
10 to 1F,
or FE:
CPU Bus Unit (see note 1).
E1: Inner board
FE: SYSMAC NET Link Unit or SYSMAC LINK Unit
Response Bit 0 (OFF): Required
1 (ON): Not required
Communications port number 0 to 7 (0 to 7)
Number of retries 0 to F (0 to 15)
Response monitor time 0000: 2 s (default)
0001 to FFFF: 0.1 to 6,553.5 s with 0.1-s increments (set by the user)
