IO Modual
For example, if A=20, the recorded number of pulses counted by DI1
circuit of AXM-IO11 is 100 (4349H to 434aH registers), then the real
number of pulses is 20×100=2000.
The parameter setting is shown in gure 3-13.
3.3 Relay Output
Relays in IO modules can work in two different modes, one is controlling
mode, and the other is alarm mode. For controlling mode, relays can
be switched on and off directly. For alarm mode, action of relays is
controlled by whether the alarm is occurred or not.
There are two modes selection for relay output, one is latching, and the
other is pulse. For the latching mode, the relay can be used to output
two statues on or off. For the pulse mode, the output of the relay
changes from off to on for a period time Ton and then goes off. Ton can
be set from 50 to 3000ms.
Note: when relay is working in alarm mode, the default output mode is
latching mode.
1. Display of Relay State
If relay state is “ON”, it means that relay is switched on. If relay state is
“OFF”, it means that relay is switched off.
Figure 3-7 shows the states of relays read on screen.
Figure 3-1 shows the states of relays read by the utility software.
