Application Examples of Ladder Sequence Program

Alarm Sequence Control Circuits Can be Reduced
The ladder sequence program is built in the UTAdvanced as standard. The ladder sequence function enables monitoring and controlling peripheral devices such as relays, thus making it possible to reduce costs.

[Conventional]
Alarm action was built by a sequence control circuit (relay, timer, etc.) outside of the controller.

arrow [UTAdvanced]
Alarm action is built by the ladder sequence program inside the UTAdvanced, thus making it possible to reduce costs.

Alarm Sequence Control Circuits can be Reduced

Example: Alarm annunciator

Host System Load is Reduced

[Conventional]
Action
Various types of analog data were captured into the host system (PLC, etc.) and calculated, and the results were processed by the field controller for control via a command.

[UTAdvanced]
Merit
The UTAdvanced with up to 4 analog inputs* enables various types of analog data to be captured directly into the controller and calculated by the ladder program, thus reducing the system-building load of the host. Action: Various types of analog data were captured into the host system (PLC, etc.) and calculated, and the results were processed by the field controller for control via a command.
* In the case of the UT55A

PC-Link

Peer to Peer

The use of the ladder sequence program makes it possible to exchange analog data and status data between communication-capable UTAdvanced.

Example: A UTAdvanced in which an input error occurs sends a signal to another UTAdvanced to enable that UTAdvanced switch to MAN operation, thus shifting the whole system into a safe mode. In such a case, the safety mechanism can be built into the UTAdvanced and is not required in the host system.

Peer to Peer

Coordinated Operation

In coordinated operation, a single UTAdvanced termperature controller is used as a master controller and multiple UTAdvanced or other UTAdvanced digital indicating controllers as slave controllers.

The slave controllers are operated in accordance with the actions of the master controller.
