How the Program Works

A basic Series 1600 Touchpanel SIMPL program is shown after this paragraph in

block diagram form. For this example, the CT-1600 is the user interface in a control

system containing a CNMSX-PRO. Assume that the CT-1600 is used to control the

state of Zone 1 in a lighting system. Zone 1 can either be turned ON or OFF or can

be ramped UP or DOWN. This example program is designed expecting that the only

serial strings input for Zone 1 are those in the COM port definition.

NOTE: If an earlier SIMPL Windows version is being used to program a system

with the LC-1600 as the user interface, the 'LC-1600' target type may not be

available. Instead, use a 'CT-1600' model or any other wired touchpanel.

To turn the lights on, 9 bytes are sent (\x02Z-01-ON\x03). When join #1 on the

touchpanel is pressed, the signal "Lights-Z1-On" goes high. When this signal goes

high, the data is sent out the port to the lighting system. A similar approach is taken

for "Lights-Z1-Off". These buttons have true feedback from the lighting system (i.e.,

when the 16 bytes (\x02Z-01-STATUS-ON\x03) enter the port, the digital signal

"Lights-Z1-On-F" goes high and drives the feedback of join #1 high). In turn, this

lights the feedback for the OFF button on the panel.

In order to ramp the zone, the appropriate command is sent to start the ramping

operation when the UP or DOWN button is pressed. When either button is released,

the output of the NOR gate goes high. This, in turn, sends the STOP command to the

lighting system, telling it to halt the ramping operation in progress.

As shown in the block diagram above, it is important to note that the user does not

have to define the [TX$] or [RX$] for the port. If strings are being triggered and

matched only in the port, the string assignment is taken care of by the compiler. If

the TX$ is defined, it can be driven by other string creation symbols (i.e., an Analog

to Serial or speed key: TXA). If RX$ is defined, it can be routed to other string

processing symbols (i.e. Serial Gather or speed key: GATHER). Another typical

usage would be if a macro were to drive the port, then the TX$ and RX$ would come

from/go to the macro definition. Refer to the help file in SIMPL Windows. From the
