(3) Ethernet / RS-232C communication command

(Print #, Input #, OpenCom, OpenNet, etc.)

All ports including the option RS-232C board are available in a virtual controller.

However, an Ethernet port requires configuration of the IP address and TCP/IP port.

Ethernet / RS-232C communication commands do not perform actual communication.

Output data from Print #, etc. is saved in the communication output file. In the input

by Input#, etc, the return value is 0 (numeric data) or blank (string). However, if you

create a communication response file, the return value depends on the file content.

Communication output file

When calling OpenCom or OpenNet command, a communication output file is created

in the \EpsonRC\Virtual\Mounted Volume\Project folder on the PC.

DummySend***.dat : Communication output file (*** is the port number)

When a communication output file already exists, the previous output data is deleted.

The file is deleted when you switch the project; save the file in a proper folder if you

need.

When executing the following program,

OpenCom #1

Print #1, 123

Print #1, "TEST DATA"

CloseCom #1

the DummySend001.dat file will contain...

123

TEST DATA

Communication response file

Copy the communication response file to the \EpsonRC\Virtual\Mounted

Volume\Project folder in before running a program. The file is deleted when you

change the project; save the file in another folder if you need to keep it.

When calling OpenCom or OpenNet command, the communication response file is

loaded.

DummyRead***.dat : Communication response file (*** is a port number)

When the following DummyRead001.dat file is used,

321

Test Data

and the following program is executed,

Integer i

String s$

OpenCom #1

Input #1, i

Input #1, s$

CloseCom #1

Print i

Print s$

the return values are i = 321 (numeric data), and s$ = "Test Data" (string).
