Click&Go User’s Manual Examples and Applications

OFF-Delay

Conversely, OFF-Delay keeps the action on running for a period of time from when the IF function

is triggered to when the THEN action is executed. For example, after pushing a button to switch

off the light in a lobby, the light stays ON for an additional 10 seconds before turning OFF so that

the user can have enough time to walk out of the building.

Using Internal Registers

Soft-key

The Internal Registers can be used to ensure that the output is under control. For example, an

output can only be triggered when the local push button is attached to a digital input and the

internal register is set.

In this example, the logic between the two IF conditions is “AND.”

Remote Control

If an output channel is coordinated by an IF condition, it is limited to the Click&Go logic and can

not be controlled by a remote PC. Users must use Internal Registers to set local and remote control

for a designated output channel. For example, an emergency alarm siren is triggered remotely by a

SCADA system when detecting high pressure or leaks. If the network is down, a local shutdown

button can also be switched ON to sound the alarm.

In this example, the logic between the two IF conditions is “OR”.

NOTE

Inter Register can be controlled by Modbus/TCP protocol, refer to the appendix for the addressed

list for all the Internal Registers.
