Name
Function
LED1
Power indicator (Green)
This indicator is on when the expansion card is powered
on.
LED3
Communication indicator
(Green)
This indicator is on when the expansion card is establishing
a connection with the control board; it blinks periodically
after the expansion card is properly connected to the
control board (the period is 1s, on for 0.5s, and off for the
other 0.5s); and it is off when the expansion card is
disconnected from the control board.
LED4
Error indicator (Red)
This indicator blinks when an error occurs (the blinking
period is 1s, on for 0.5s, and off for the other 0.5s). You can
query the error types on the controlling computer Auto
Station.
This indicator is off when there is no error.
LED5
Power indicator
This indicator is on when the expansion card is powered
on.
LED6
RUN indicator (Green)
This indicator is on when the PLC program is running; it is
off when the PLC program stops.
The SPC502-00 programmable expansion card can replace some micro PLC applications. It adopts
the global mainstream development environment PLC, supporting the instruction language (IL), ladder
diagram (LD), and sequential function chart (SFC). It provides a user program storage space of 16K
steps and data storage space of 8K words, and supports saving data of 1K words at power failure,
which facilitate customers' secondary development and meets the customization requirements.
The SPC502-00 programmable expansion card provides 6 digital inputs, 2 relay outputs, 1 analog
input, 1 analog output, 1 RS485 communication channel (supports master/slave switchover). It is user-
friendly, providing relay outputs through European-type screw terminals and other inputs and outputs
through spring terminals.
