10.1 Application
The monitoring module can be used in the expansion units of the
programmable controllers S5-115U, S5-135U and S5-155U.
programmable controllers S5-115U, S5-135U and S5-155U.
The module monitors the data bus, the address bus and the control signals
MEMW/, MEMR/ and RDY/. Faults are displayed via four red LEDs on the
front panel. A group signal is output at the same time via a floating contact.
Following a fault, the module can be reset by means of the RESET key on
the front panel or the RESET input (see Section 10.2.3).
