3.5.2 Diagnostic LED Panel
Use the matrix display on the CPU Module for diagnostics and testing of I/O-DC 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-DC slot LED is on. The LEDs will light in 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 3-10 shows indications from the module in slot number 2 (M2). 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 3 (OUT - 3)
Table 3-6 specifies the LED indications for the I/O-DC Module.
