Note:

• In [Label] tab, if select [ON=OFF (use state 0)] check box, both state 0 and 1 follow the settings of state 0.

Overview

Word Lamp object displays the state according to the value of a designated word register. Up to 256 states are available. When the value of the register is 0, State 0 appearance of the object is displayed, and with the register value being 1 the object displays State 1, and so on.

Configuration

Mode / Offset	Word Lamp object offers the following three modes: Value The state is displayed according to the value in the designated word address and plus the [Offset]. As shown below, if the value within LW-200 is 3, since the offset is set to 3, the shape of state 0 is displayed. (value 3 – offset 3) LSB Convert the value from decimal to binary. The least significant active bit in a binary data word selects the state displayed. Bit Combination Lamp state depends on the states of bit combinations, where PLC 1 represents the least significant bit (LSB), PLC 2 represents the next LSB, and so on. Maximum number of bit is 4, for a total of 16 states. Changing [No. of states] in Attribute group box changes the number of read addresses. Change state by time The state displayed changes on a time basis. The frequency can be set.
Read address	Click [Setting] to select the [PLC name], [Address], [Device type], [System tag], [Index register] of the word device that controls the [Word Lamp] object. Users can also set address in [General] tab while adding a new object.
Attribute	No. of states The number of states is utilized by the object. The state is numbered from 0, so the number of states minus 1 will be the state number. If the value within the word register is ≥ [No. of states] defined in Attribute, the highest state will be displayed. If the number of states is set to 8, the valid states will be 0, 1, 2, …, 7. In this case if the word value is 8 or higher, the system will display the state 7 shape. Hide picture/shape if no corresponding picture for current state If selected, when there are not enough pictures to represent all the states, hides the picture. Otherwise, displays the last state.

Note:

• In [Label] tab, Language 1 determines the relevant settings of the font. For Language 2~8, only the font size can be changed and other settings follow Language 1.

Overview

The Set Bit object provides two operation modes: manual or automatic. Manual mode can trigger a designated bit address to change the state between ON and OFF when the object is touched. In automatic mode, the bit is automatically activated when a pre-defined condition occurs; touching the button will not be effective.

Configuration

Click [Object] » [Set Bit] icon on the toolbar to open a Set Bit object property dialog box. Set up the properties, press OK button, and a new Set Bit object will be created.

Set OFF when backlight off (N/A for cMT-SVR) Set the bit OFF when the backlight is turned OFF.
Macro	Set Bit object can trigger the start of a Macro routine when the Macro has been created in advance.
Trigger mode	If [Set style] is set to [Toggle], there is a further selection to make of whether the macro operates after Off to ON, ON to OFF transition, or at both the changes of state.

Note:

• In [Label] tab, if select [ON=OFF (use state 0)] check box, both state 0 and 1 follow the settings of state 0.
• Using address types other than PLB or PLW_Bit for Set Bit objects with [Periodic Toggle] attribute is not supported by cMT-SVR.
• The Set Style setting in the General tab determines which settings are available in the Security tab. When the Set Style is [Set ON / OFF when window opens], there will be no settings available in the Security tab.
• When [Execute macro] is selected, the sequence in which the object’s write operation and the macro execution is determined by the HMI runtime. In order to exactly arrange the write operation and the macro execution in the desired way, specify the sequence by configuring a Combo Button instead.

Overview

The Set Word object provides two operation modes: manual or automatic. Manual mode can change the value in a designated word address when the object is touched. In automatic mode, the word register is automatically activated when a pre-defined condition occurs; touching the button will not be effective.

Dynamic address	LW-n	LW-n	LW-n
Bottom limit	LW-n	LW-n	LW-n
Upper limit	LW-n+1	LW-n+2	LW-n+4

When Dynamic Address is LW-100, the rule of setting Upper / Bottom limit is:

Description

Interlock

Use interlock function When this option is enabled and [Word] is selected, whether the object is operable depends on the condition of a word address specified in [Trigger if value is:]. In the settings above, the object is operable only when the value in LW-1 is greater than 1. Hide when disabled The object is hidden when the specified condition does not occur in the specified word address. Grayed label when disabled The label of the object turns gray when the specified condition does not occur in the specified word address. Trigger if value is: This setting is for specifying a trigger condition. The available options are: >, <, ==, <>, >=, and <=. A tolerance value can be set for conditions == and <>. For example: When Hide when disabled is selected, Trigger if value is is set to == 10, and Tolerance is set to 1, the object will be hidden and is not operable when the value in the specified word address is greater than or equal to 11, or smaller than or equal to 9.

Note:

• Using address types other than PLW for Set Word objects with automatic attributes such as [Periodic set up], [Periodic set down], [Automatic JOG++], [Automatic JOG–], and
• [Periodic JOG++]…etc, is not supported by cMT-SVR.
