Discrete I/O modules
By software configuration, specific functions can be assigned to certain inputs. The
first four inputs of a discrete I/O module located in slot 1 of a TSX Micro PLC can be
configured as discrete inputs, latching inputs, event-triggered inputs or up/down
counter inputs.
These are inputs %I1.0 to %I1.3. The principle is that, on a pulse which is shorter
than the PLC scan, the pulse is stored and processed on the next PLC scan. The
pulse is taken into account when the input changes state (rising and/or falling edge
depending on the selected configuration).
These are inputs %I1.0 to %I1.3. On command events, the application program is
diverted directly to the event processing associated with the input causing the event.
The event is taken into account when the input changes state (rising and/or falling
edge depending on the selected configuration).
These are inputs %I1.0 to %I1.3. Depending on the software configuration, these
inputs enable the creation of up to 2 up/down counter channels, each of which can
execute one of the following functions independently: upcounting function,
downcounting function, up/down counting with or without direction discrimination.
Input %I1.8 can be set to control the RUN/STOP command on the PLC. This is taken
into account on a rising edge. At STOP command via an input has priority over the
RUN command via the terminal or network.
Input %I1.9 can be set to back up the application program in the Flash EPROM
memory (in the internal RAM) and the first 1000 words %MWi maximum on a rising
edge.
On a PLC base, output %Q2.0 can, after configuration, be assigned to the ALARM
function. When setting the PLC to RUN and if no blocking fault is detected, the alarm
output changes to state 1. It can be used in safety circuits external to the PLC, for
example to control the output preactuators power supply, or the TSX Micro PLC
power supply.
