“Over” event

A start event 1 occurs when the measured value rises above the

threshold value for event detection.

- unr[Under]

“Under” event

A start event 1 occurs when the measured value falls below the

threshold value for event detection.

1. Over and Under current events consist of start and end events.

Details on Over Event settings are as follows.

Description

Threshold value – Hysteresis

Start event of Over event

A start event occurs when the measured value exceeds the Over threshold value. A

start event occurs again only if the measured value rises above the threshold value

again after the value drops below the end level and an end event occurs.

End event of Over event

An end event occurs when the measured value drops below the end level.

Hysteresis

When the measured values often exceed and fall below the threshold value for event

detection, it can cause multiple events to occur. Thus, for effective event

management, it is necessary to set up a proper hysteresis level. The default value is

0.4 mA, and it can be configured.

Details on Under Event settings are as follows.

An end event occurs when the measured value rises above the end level.

When the measured values often exceed and fall below the threshold value for event

detection, it can cause multiple events to occur.

Thus, for effective event management, it is necessary to set up a proper hysteresis

Uint16

PRW

Base register for accessing registers 3802-4000

By reading this register, the data collected from the module ID

assigned to register 1261 can be fetched to registers 3802-4000.

After a successful fetch, the Bit[15] is indicated as 1.

By writing 1 to this register, data on registers 3802-4000 are

applied to the designated module.

Detection code for the IDC module: 3

By writing the detection code 3 to the register, device setup for

the IDC module can be performed. If the detection code is not

entered properly, device setup for the IDC module cannot be

performed.

channel 1

Uint16

PRW

Sets up the method of displaying the measured current value

ranging from -20 to 20mA

If it is set to 1, the negative sign of current is removed and only

the positive current value is displayed.

0 : -20 to 20 mA positive or negative value available

1: (default) 0 to 20 mA only positive value available

Measured current values can be converted to a value the user

wants to use. For data conversion, the minimum value in the

current range should be entered. If register 3804 is set to 0(4-

20mA), the converted value for 4 mA should be entered. If set to

1(0-20mA), the converted value for 0 mA should be entered.
