Indicator
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 upper 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 EC-PC502-00 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 EC-PC502-00 programmable expansion card provides 6 digital inputs, 2 relay outputs, 1 analog
