Serial Communications
Section 6-3
Create frame in the host com-
puter and send the command to
the PLC. Receive the response
from the PLC.
Application:
Use these methods when com-
municating primarily from the
host computer to PLCs in the
network.
Remarks:
The FINS command must be
placed between a Host Link
header and terminator and then
sent by the host computer.
Send the command frame with
the CPU Unit’s SEND, RECV, or
CMND instruction. Receive
response from the host com-
puter.
Application:
Use this method when commu-
nicating primarily from the PLC
to the host computer to transmit
status information, such as error
information.
Remarks:
The FINS command will be
placed between a Host Link
header and terminator when it is
sent. The FINS command must
be interpreted at the host com-
puter and then the host com-
puter must return a response.
