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.

Example:

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.

Overview:

The UTAdvanced Digital Indicating Controller comes standard with ladder sequence function. The ladder sequence function can handle measured and computed values from the controller. Using this function, the UTAdvanced converts outputs from other controllers such as YS1500 to time proportioning outputs.

Overview:

This introduces a system that uses Ethernet communications to acquire measured values, target values, and control output values from a controller installed on site into a PLC at high speed (ten units' worth within one second).

Overview:

Controls temperature in, and acquires data from, various internal components of plastic film manufacturing equipment. An easy to use, high cost-performance data acquisition and monitoring system can be assembled by using Ethernet compatible instruments and GA10.

Overview:

The TC series of temperature controllers is perfect for controlling the heating temperature of sealing parts and the temperature of sealing rolls (pre-heating) in a variety of different wrapping machinery.

Overview:

Load devices are sometimes used when evaluating (measuring) DUT performance. Depending on the parameter being evaluated, multiple controllers can be employed to control the performance of the load device, but there are also times when the load device uses only one actuator.

See the UTAdvanced Series Communication Interface (RS-485, Ethernet) User's Manual.
For communication errors, the left side decimal point of the symbol display on the main unit blinks. If the SD or RD indicators light on upstream devices, check whether both are blinking.
You can specify PID parameter groups for each SP number. Each PID parameter group includes PID, output limiter, hysteresis, and other items.
For controllers, the status detection minimum hold time is the control interval + 50 ms. Also, for indicating alarms, it's the input sampling interval + 50 ms.
It's time proportional PID. That means that in addition to relay output, it can support TRIAC and voltage output. With time proportional output, control calculation result is output using the pulse width of an ON/OFF signal proportional to time. ...
