o
The internal bit is reset with the delay P.2904
– P.2905 from when the
“activation condition” becomes false.
•
2
– Pulse.
o
The internal bit is reset while
the “reset condition” is true.
o
The internal bit is set for the time configured with P.2902
– P.2903 each time
the “activation condition” changes from false to true.
o
The internal bit is set for the time configured with P.2904
– P.2905 each time
the “activation condition” changes from true to false.
•
3
– Free run
o
The internal bit is reset while
the “reset condition” is true.
o
The internal bit is reset while
the “activation condition” is false.
o
While the “activation condition” is true, the internal bit is managed as a square
wave: it is set for the time configured with P.2902
– P.2903, then it is reset for
the time configured with P.2904
– P.2905, and so on.
•
4
– Set/Reset
o
The internal bit is reset while the “reset condition” is true.
o
The in
ternal bit is set if the “activation condition” is true and the “reset
condition” is false.
o
The internal bit keeps its previous status if the “activation condition” is false
and th
e “reset condition” is false.
The following example manages a digital output related to the internal bit of the timer 1:
The controller can manage an analogue or a GSM modem. The modem can be connected to
the serial port JA.
The controller can perform/receive data calls (data over voice, not TCP/IP) and to send/receive
SMS. For a complete description of this feature see document [3].
The controller is always ready to answer incoming data calls and to receive SMS. On the
contrary, it must be configured to make data calls (on the other side a PC with a modem and
with SicesSupervisor software is required) or to send SMS. The related parameters are:
•
P.0456
– Plant name. You can set here an alphanumeric name for the plant. The
controller will include this name in all SMS sent; it must correspond to the name of a
plant into the SicesSupervisor software, in case of data calls (it must be unique).
