Outputs
Table 2: Type and number of outputs
The transistor outputs are provided with a short-circuit monitoring
function. In the event that a short-circuit occurs at one of the
outputs, this is indicated via the diagnostics inputs I15/I16. I15 is
set to 1 if a short-circuit occurs at the outputs Q1 to Q4. Input I16
is toggled if a short-circuit occurs on Q5 to Q6.
Memory card (MCC)
The memory card is used for data storage and supports the FAT16
file system.
Memory card data
On the memory card you can save the following data:
A brief description of the browser commands is provided from
page 59.
Data access on the memory card
Functions such as FileOpen or FileRead allow you to access the
files of the memory card from the user program. These functions
are provided in the library EC_File.lib and are described in the
Function Blocks manual (MN05010002Z-EN; previously
AWB2786-1456GB).
RUN/STOP/SF and CAN/NET LEDs
After power up, the CPU can switch to the following states, as
indicated by the LEDs:
Table 3: LED status indicator
If the CPU is in RUN status, the CAN/NET LED indicates the
following states:

Caution!
Scan I15/I16 in the program. In the event of a short-circuit
set the outputs to 0 in order to prevent the thermal
overload of the output circuit.
