Memory Access
You can access (read/ write) to any of the internal memory of the V7i, the PLC
memory connected to the V7i, and the temperature control memory.
In this case, you need to set each parameter in the table (page 28-12) and
create an HTM (SHT) file for sending to the V7i. You can access (read/ write) to
the desired memory from this HTM (SHT) file by specifying the CGI function
(MemAcs.cgi) prepared in the V7i.
Memory Access Flowchart
The procedure of memory access is as follows:
CGI Function (MemAcs.cgi)
“MemAcs.cgi” is a prepared CGI function to read or write memory of devices
connected to the V7i. Specify the parameters with the SHT file to start the CGI
function. The CGI recognizes whether to read or write according to the received
parameter values. For read, it sends a monitor table to the Web browser. For
write, it sends its writing result to the Web browser.
