A hand held Remote Control is used to program the ALPHA sign to store messages for later use by the PLC. For example, let’s say we want to display any of three different messages that are stored in files A, B and C on an ALPHA sign. The message displayed is based on a “closed switch” input to the PLC. When a switch is closed, the associated message is displayed and remains until a different switch is closed. You can see the ALPHA Remote Control programming.
