NETWORK RECEIVE Instruction - RECV(98)
The RECV(98) instruction enables the local node to write to its memory, data
sent from a node either on a local or remote network.
Format
The format of the RECV(98) instruction is as follows:
Control Data
Set the source node address to $00 to send data within the PLC executing the
instruction.
Note
Transmissions cannot be received from the PLC executing RECV(98).
1,2,3...
1.
Number of Words
Set the total number of words to be transferred.
2.
Source Network Address
Set the Source network address to 00 if you send the data to within the lo-
cal network. If more than one SYSMAC LINK Unit, Controller Link Unit, or
Ethernet Unit is mounted on the PLC, the network of the Unit with the
smallest unit address will be considered to the local network.
3.
Source Node Address
Set the source node address to 00 for devices at the local node.
4.
Source Unit Address
Set the source unit address to 00 if the destination is a PLC. If it is a user
application on a computer, set the destination unit to 01 (user application
01). For a BASIC Unit, add 10 to the unit number (0 to F) so that the des-
tination unit address is from 10 to 1F.
5.
Response Bit (Bit 15 of C+3)
Always set this bit to OFF (0: response required).
