To use a global variable as a local variable, it is necessary to declare it as EXTERN before use. Local variable is available only in a designated program. Direct variable (variables with user specified address) can be used in the program. In addition, a comment can be entered to the direct variable.

5.2 Global/Direct Variable Global/Direct variables consist of global variables, direct variable comments and flags. A Global variable declare the variable to be used for a program or displays a list of the declared variables, based on the available variables. Direct variable comment declares the direct variable comment available in a program or displays the comment. The Flag displays a list of flags provided by the declaration. The following are the different types of flags:

System flag

High Speed link flag

P2P flag

PID flag.

Global Variable

Global variables are declared and the list is displayed.

4 Device Area setup tab: used to specify the area to preserve (latch area) of

[Basic Parameters] information even when PLC power is off.



Step Action


Select latch area Used to specify data area to preserve. It is the representative flag to control area 1 and area 2 of the right latch area table. If the check box is not selected, value specified in the right latch area table will be ignored.

It is used to specify desired latch area for each device, to decide to use the respective device and to select the area. Area 1 and area 2 cannot be used as overlapped, and the maximum size of each latch area is the maximum size of the device area.

Timer boundary Timer areas are divided into 100ms, 10ms, 1ms and 0.1ms. This area can be selected as the latch area within the specified value of the left timer limit area. Like other devices the areas cannot be set as overwritten. The number of timers to use can be adjusted, and the value specified will have a great influence on the timer of LD diagram or IL program. Default for setting value of each timer is as follows;



Step Action

T100ms Start: 0 End: 999



T0.1ms Start: 2000 End: 2047

When the timer limit specified is the default, the timer will be automatically in 100ms unit with T100 if used in LD diagram. It is because T100 is in the area of T100ms. In order to use the timer with a cycle of 10ms in basic setting, optional address among T1000 ~ T1499 needs to be used. You can specify the timer area of each cycle to assign more memory areas to the cycle desired to apply more.

In timer limit setting, different cycles can be set as overlapped. In addition, since Start and End of the area are always 0 and 2047 fixed, their modification is unavailable. Each cycle needs to be used with its size divided in this area.

5 Error Operation Setup tab: Specifies the operation method when an error

occurs on the PLC.



Step Action

SOE History Reset with recent history: use this to save the most recent event.

If the events exceed 300, the oldest event is deleted and the last one is saved.

Retain initial history: use this to retain the first event.

If the events exceed 300, the last one will not be saved.

Event setting details

Set up the input condition of the event.

Type: Rise, Fall or simultaneously, Rise/Fall of event can be set up.

Event conditions can be set up for each input contact point.

Chattering: Abnormal signals not related with event can be processed as chattering.

(Setting range: 2~127)

Example of input filter setting

Condition is as follows.

Input filter: 1ms

Detail event setting: ‘Rise/Fall’ events simultaneously

Sequence diagram of event occurrence is as follows.



Chatter Setting

Chatter setting enables the module to identify an event repeated many times during a short period of time as chattering, and not an effective event. Some sensors using mechanical contacts may cause chattering, which can be eliminated with this function.

Setting items

1. Number of events: 2~127 (‘0’: detection is disabled)

2. Event number: Enter the number of the events including the first effective signal (min. 2)

3. Chatter detection time (duration): If this chatter detection time is passed from the time the first effective event was detected, the chatter detection function for the specific event frequency is terminated, even if the set-up number of chattering is not completed.

4. Min. chatter detection time (duration): Co-related with the set up chattering event number.



In addition, since an event has passed the input filter, it should satisfy following criteria;

(Number of Events × Input Filter Value) ＜ Chatter Detection Time (Duration)

or,

Input Filter Value ＜ (Chatter Detection Time (Duration) / Number of Events)

For example,

If, chatter detection time = 30ms, number of chattering events = 5,

30ms ÷ 5 = 6ms,

Therefore, the input filter must be less than 6ms.

Example of chatter setting

Condition:

Input filter: 1ms

Detail event setting: ‘Rise’ event

Chatter event: 4

Chatter time: 8ms

Sequence diagram of event occurrence is as follows.
