PLC-5 Channel 0 Simplex Example
This example demonstrates how to use the RS232 Channel 0 of supporting
members of the Allen-Bradley PLC-5 family to trigger a Dataliner DL50
display. In the example, a counter is used to simulate changing variable data,
which could be a motor speed or a temperature. This will demonstrate how
variable data may be incorporated into messages.
The program below will display the message “Temp ##” in green (red on
F11J or F21J), where ## represents the sample variable. The text size will
depend on the character size setting on the DL50 display.
Temp ##
Channel 0 Configuration
The first step is to configure the PLC channel 0 port to communicate with a
DL50 slave. Table 6.C shows the user mode configuration of the PLC
channel 0. Note that the baud rate should match that being used by the DL50.
