2.1 Architecture and Function
The Human-Machine Interface (HMI) is mainly used to set the testing modes.
The Programmable Logic Controller (PLC) is mainly used to control the PCB I/O Board
Holder as well as exchange sampling or Pass/Fail signals (through the RS-232 cable);
usually when the machine is set to In-Line mode there will be a greater chance of I/O board
issues or loader/unloader error. The possible errors and solutions are introduced below.
1) If the PCBs to be tested are relatively long, when the testing is completed and the PCB
is unloaded and the next PCB loaded, the PCBs may cover Sensor1 (Loader Sensor)
and Sensor2 (Brake Sensor) at the same time. The current program logic of the PLC
requires that Sensor1 and Sensor2 must not both be triggered at the same time, or the
alarm buzzer will activate and the new board will automatically be unloaded. In such a
situation the relative positions of Sensor1 and Sensor2 should be adjusted to avoid
being simultaneously triggered and leading to abnormal operation. The exception is
when equipment is set for simultaneous In and Out.
2) Loader/Unloader Connection: Please install wiring according to SMEMA specifications.

The Human-Machine Interface (VPLC) allows you to control the machine by the program.
VPLC window should show up automatically when the main program starts.
