UP351 Program Controller

Meter alarms are for outputting alarms regardless of the operation mode. PV and time events are used only during program operation. Local events are action events used only during local operation.
By design, UP350/351 program patterns are set by using the parameter setting tool.
In the controller specifications, communication and LOCK parameters cannot be set with the LL100/LL200.
Yes, by setting RET=3(OUT). (Note that this is position proportional only.)
Yes. The selection in the OT=0 to 3 setting in the setup parameters will be 1 output.
This is a function in which output occurs a specified time after an alarm set point is exceeded. If you clear the alarm point during operation of the timer, the timer is reset.
Can I perform CC-Link communication?
Yes, by using the UTAdvanced series.
Once input is set, IN is not displayed when you turn the power ON.
You can use the conversion tool. You don’t have to do anything after you create it. The steps are as follows: Perform the Green conversion using the conversion tool. Write the converted file to the UTA (with the CC-Link option) main unit. ...
This function supplies power to 2-wire transmitters. It differs depending on the specifications of the transmitter, but the input accepts 100 Ω resistors. 100 Ω resistor (model: X010-100-2, sold seperately)
These are used when 2-wire transmitters are used in the field. They provide cost savings since they do not need to be purchased separately. 24 V (21.6–28.0 VDC, 30 mA MAX) sensor power supplies can be specified with the following models: UT551,...
I can't switch the SP.
Check whether you are trying to switch it via communication, or whether it is the zone PID.
Yes, if it is a heating/cooling type.
The DO206 items are used when in cascade control mode. For other modes, use DO201.
Set the following: P=100, I=D=OFF, DR=DIR (direct action), MR=0, SP=0.
Even when you expand the applicable range of the PID constant, the process states fluctuate, or response is unstable and hunting occurs (control responses fluctuate), this function is effective for stabilizing control and suppressing hunting. Normall...
With the UT300 series, only use 1PID. With UT400/500/700 models, the PID used just prior to switching to remote input is used. When using SP switching during remote input, only the PID switches.
Output stops when the status is STOP.
When RET=1 or 2, the STOP has no effect.
Why don't PID items appear?
They don't appear with OT=3 ON/OFF control.
The UT300/400/500/700 series, and the UP350/351/550/750. However, the LL200 custom computation function is only compatible with the UT750/UP750.
Ladder communication is used when communicating with the Computer link unit/Serial communication unit. Modbus/RTU is used for communication with the Modbus communication module.
Sample programs and dedicated communication materials are available for MELSEC-A/MELSEC-Q.
What are direct and reverse action?
Generally, reverse action means heating control and direct action means cooling control. When output is reverse action, output is ON during PVSP.
Almost all items can be accessed, including PV reading, SP writing, and PID setting.
This is a limit on the number of times you can write to the element used (EEP-ROM).
If the operation mode is STOP or MAN, they are not displayed.
It depends on the model. The following lists the readable registers by model. UT100 series: D0001–D0009 UT300 series: D0001–D0008 UT400/UT500/UT700 series: D0001–D0025 UP350: D0001–D0008 UP550/UP750: D0001–D0025 ...
Set both item P on the heating side and item Pc on the cooling side to 0.0.
If you set + dead zone in the settings, you can get an area where no outputs occur. If you set - dead zone, you can get an area where both outputs occur at the same time.
Yes, the Auto tuning function.
The common for all GREEN series alarm relay outputs are shared. In the UTAdvanced series, each alarm relay output has its own common. If used the same way, use external wiring to connect common to common.
Program changes for reading PV and OUT, writing SP, and other basic parameters are not necessary. There are registers and relays that support the GREEN series. For details see the UTAdvanced series communication interface (RS-485, Ethernet) user'...
Yes, you can use the GREEN-UTAdvanced parameter data conversion tool (available as free download). Using the LL100/LL200 parameter setting tool, save the GREEN series parameters to a file, convert them using the conversion tool, then apply the settin...
This is an overshoot suppression function that uses fuzzy logic. It constantly monitors deviation, and if it detects the possibility of an overshoot, it automatically changes the set point to a somewhat lower temp value (sub set point SSP). When y...
Ladder communication is a protocol for communication with PLCs. Aside from Yokogawa PLCs, you can communicate with Mitsubishi MELSEC-Q/A series calculator link units (using A1SJ71UC24-R4 or A1SJ71C24-R4). ...
This is a protocol for communication with general purpose PCs and graphic panels, and also the FA-M3: You can communicate with Yokogawa PLC range free controller UT link modules and serial communication modules. Also, you can easily connect with PLCs...
The output is 0% if there is a hardware failure such as an internal microprocessor.
This is a protocol for communication with general purpose PCs and graphic panels. The UT130/UT150 can communicate with standard PCs. ...
As for individually writing parameters via CC-Link, changing OUT area values constitutes a write request. In your case, since the OUT area value hasn't changed from the previous value, the SP value is notoverwritten. As a fix, periodically copy t...
There is no current input range.
Use a resistor to input current as voltage. A resistor is available: X010-250-2 (250 Ω).
Do Green series controllers support Ethernet?
Yes. This requires an RS-485/Ethernet converter such as VJET. The controller must also have a communication option. Some models can be connected directly with the UTAdvanced series.
The PV value can be written by using the ladder sequence function of UTAdvanced series. However, when communication is interrupted, the PV value is retained.
600 Ω.
Yes, but if you change some parameters, others will be initialized. We do not recommend that you make changes while in operation.
These cannot be set when in Custom Computation mode.
There are 2 types of output available, FAIL and "failure diagnosis."
PCBs (polychlorinated biphenyl) were banned from manufacturing and imports in 1975. The GREEN series began to be manufactured in 1997, and do not include PCBs.
Check whether the wiring to the power supply terminal is correct. If only the LCD on the UT/UP700 does not display, a custom computation may be set for no display. If the PV display is also blank, this may indicate product failure. Please contact you...
The sensor wire on the input side might be broken or disconnected.
How do I change the input type?
If you change the input type, parameters will be initialized. We do not recommend that you make changes while in operation.
No. When an alarm occurs, it automatically recovers if values enter the normal range.
What are energize/de-energize alarms?
For energize alarms, ON contact results when an alarm occurs. For de-energize alarms, OFF contact results when an alarm occurs. Note that OFF contact also results when the power fails.
The are set with a real number. For temperature, it is set in degrees Celsius.
