Function Modules
Typical Application as "On-Delay Timer"
A timer module is mounted at slot 5. A time of 270 s is set on channel "0" of this module by means
of the time-range selector and the potentiometer. The timer is started when input 0.0 is "1".
A lamp lights up (output 4.0) when the timer has run down.

Terminal Connections
No process peripherals are connected to this
module.
Unlike the internal timers, times can be set or
modified using a timer module without
making any program modifications.
The timer must not be scanned in the program scan cycle in which it was
enabled since the CPU would not receive the acknowledgement that the
timer had started until one program scan later.
If flag 65.0 is "1" and the timer has run down (AN I 5.0), output 4.0 is set
to "1".
If the "Timer started" message has been sent to the CPU, the flag is set.
If I 0.0 is "0", the lamp is switched off.
The timer is started if I 0.0 is "1".
