Button String Commands (Cont.)
WORKING?
Verifies the com-
munication
between touch
panels through
the use of the on-
panel editor.
Responding touch panels tell the sending touch panel to change its Main page to the color
white.
Syntax:
"WORKING?"
Example:
• MCP panel serial port is connected to TPI program port.
• MCP panel wants to verify communication between the TPI and itself.
• MCP panel issues "WORKING?" to its serial port. It will be sent as $SP "WORKING?".
• TPI receives the command and responds to the MCP panel by telling it to set the Main
page background to white. Thus communication is verified.
