RS-232 Send Message Structure (Asynchronous)

Below is a description of the possible message fields for the send structures.

with synchronous mode. The order of the message fields does not matter.

However, the field names are case sensitive.

Timeout Time, in seconds, the driver block waits for data to be

returned. Default value =

0.049.

EOM Character at the end of a message.

•

Send_Receive_struct(index).inputports — Defines

the number of input ports for the driver block.

•

Send_Receive_struct(index).recdata — Data received

through the serial port. Default value =

[ ].

Description

SendData Data and format sent to the RS-232 device. Default

value =

’’

InputPorts Number of input ports for the driver block. Data from the

input ports is sent to the RS-232 device with the message

field

.SendData. Default value = []. The highest number

you enter determines the number of input ports on the

driver block.

For example, the following message creates two input ports

on the driver block,

RS232_Send_Receive(1).InputPorts= [1 2];
