4-4-5 Commands from PCs
The SEND(192), RECV(193), and CMND(194) instructions are used in the PC’s
user program to execute data communications or controlling the host computer
via Host Link System commands. This can be done either to a host computer
connected to the local PC or to a host computer connected to a PC linked to the
local PC via one or more networks. To send commands using SEND(192),
RECV(193), and CMND(194) instructions to the host computer, the control data
must be set as explained below. Refer to the CV-series PC Operation Manual:
Ladder Diagrams for details.
