3.4.2 Diagnostic LED Panel
Use the matrix display on the CPU Module for diagnostics and testing of the I/O-AC
Module. The top row indicates which module (CPU, M1, M2 or M3) the LED panel is set to
display and the blue numerals on the LED panel are the I/O indications.
Press the pushbutton (P.B.) once momentarily to activate the LED panel. Then, press the
pushbutton until the I/O-AC slot LED is on. The LEDs will light in the following order: CPU,
M1 (I/O Module 1), M2 (I/O Module 2), and M3 (I/O Module 3). Verify that the relevant
LED is lit.
For example; Figure 3-7 shows indications from the module in slot number 1 (M1). LED
number 1 is on, indicating that the module is reading signal from Input number 1 (DI - 1).
LED number 11 is on, indicating that the module is energizing Output number 9 (OUT - 9)
Table 3-4 specifies the LED indications for the I/O-AC Module.
