Table 4: Example of Tagname for Non-batch Process Control
TAGS FOR BATCH CONTROL APPLICATIONS The Batch tag-naming format covers Control Modules and Equipment Modules.
Control Module HMI Tagnaming Conventions
Tagnames for the HMI generated use the following format: Where, CM pp u ext
Control Module PLC Number
tagname extension (Refer to the Device Control Modules Section) CM_ppu_xxx_ext
unit number related to Control Module
EQUIPMENT MODULE HMI TAGNAMING CONVENTIONS Tagnames for the HMI are generated using the following format: Where, EM pp u xxx ext
10.C.4. WINDOW NAMING CONVENTION
The following naming conventions are recommended for Intouch applications.
NAMING STRUCTURE
The window naming format is represented below. The Maximum number of characters per window name, including underscore characters, is 26.
AAAA_BBBBBBBBBBBBBBB_CC_DE
The following table describes the naming format for projects: Field AAAA Description 4 characters or less that describe the Area of the process or machine. This field is optional and can be deleted from tag names if there is no Area for an application. In this case the naming convention is BBBBBBBBBB_CCCC BBBBBBBBBB 15 characters or less that describe the Device. Examples are: FV2345, AcidPump, LIC54321, Mtr382 CC D E _ 2 characters describe Window type and location. 1 character to describe Window Application Class 1 character to describe Window Revision Number Underscore characters are Field Separators.
Equipment Module PLC Number unit number
three-digit Equipment Module number tagname extenstion EM_ppu_xxx_ext

10.C.5. WINDOW NAVIGATION METHODOLOGY
The standards and techniques for window navigation will be discussed in this section. Replacement Type Windows are to be used for all Default and normal operational windows for the Center and Bottom Window Areas. Pop-up type windows on the other hand, can be used for Default and normal operational Windows for the Top Window Area. Popup Type Windows can also be used for special applications in the Center and Bottom Areas.
STANDARD SCREEN LAYOUT
The window display or screen will be divided into three (3) window areas: ? ?
CENTER WINDOW
This area displays Overview windows that show the Process or Machine graphic display. ?
The window area sizes and locations are shown below.
BOTTOM WINDOW
This area is used for various functions such as Logons, Alarming, etc.
TOP WINDOW
This window is used to select different windows for the center window.
Figure 1: Standard Screen Layout
WINDOW NAVIGATION FOR REPLACEMENT TYPE WINDOWS The standard to be discussed below are for Center and Bottom windows.
1. Tag Required for Each Window
a. WindowName
Tag Data Type
Tag Value
Tag Name
b. WindowName ID
This tag is used to determine if each window is being displayed. Tag Data Type: Memory Discrete
Tag Value: Indicates Window State (Open = 1, Closed = 0)
c. WindowName_DateC
Tag Data Type: Memory Message
d. WindowName_DateM
Tag Data Type: Memory Message
e. WindowName_Ver
Tag Data Type: Memory Message
f. WindowName_WhoC
Tag Data Type: Memory Message
g. WindowName_WhoM
Tag Data Type: Memory Message
2. System-Wide Tags Required for Center and Bottom Window Area
a. Current Window Being Displayed
i. SYS_CenterCurrent_REP ii. SYS_BottomCurrent_REP
Tag Data Type : Memory Message Tag Value
:
Holds
Name
of
Current
Replacement Window being displayed.
How to Set
: Tag values set in Window Scripts for each window: “ON SHOW”
: Memory Message : Holds Window Name : Not Used
b. Last Window displayed before the current window
i. SYS_CenterLast_REP ii. SYS_BottomLast_REP
Tag Data Type : Memory Message Tag Value
Window
that was displayed. How to Set
:Tag values set in Window Scripts for each window: “ON HIDE”
: Holds Name of the Last Replacement
iii. SYS_CenterMain_REP
Tag Data Type : Memory Message Tag Value
: Holds Name of the Last Default CenterMain Replacement Window that was displayed.
Projects must determine this window name.
iv. SYS_BottomMain_REP (replaces old SYS_Bottom_Last)
Tag Data Type Tag Value
BottomMain
Replacement Window that was displayed.
For most projects there is only 1 Default Bottom window. This tag will always contain the value: SYS_BottomMain_BR_00
? ?
Tag value of “SYS_BottomMain_BR_00” typed into tag as Default value used on startup of InTouch application.
Tag value set in the ON SHOW script for Bottom Main Window. This allows flexibility for projects that need multiple Bottom Main windows. For most projects this will use the same value as step a.
c. Next Window to be displayed next
There will be no NEXT Window System-Wide tags for Replacement Type Windows. Scripts that call windows for display will use actual Window name, except for scripts that call the LAST window as described above
3. Default Windows
There are two options in setting this tag:
: Memory Message
: Holds Name of the Last Default
