* Module 1 Graphics Builder图形组态工具及与点无关的图形 1. 读取Graphic Builder工具 2. Graphic Builder组态环境 3. 建立与点无关的图形 ARC Rubberband (BACKGROUND) LINE (BACKGROUND) CIRCLE ELLIPSE (BACKGROUND) POLIGON (BACKGROUND) RECTANGLE (BACKGROUND) DOT (BACKGROUND) OL_RECTANGLE (BACKGROUND) MULTI_TEXT (BACKGROUND) SHAPE (BACKGROUND) TIME DATE (FOREGROUND) OL_BUTTON FOR POKE TYPE 2 (KEYBOARD) 4. 使用图形中的线模式line patterns 、线宽line widths 、填充图形 fill patterns和文本属性text attributes： LINE_PAT LINE_WIDTH FILL_PAT Text attributes 5. 在二个GB组态界面拷贝图形。 图号范围: !!!!!!!!!!!流程图的类型!!!!!!!!!!!!!!! Module 2 建立与点有关的图形 1. 动态图的类型: PROCESS_PT: 模拟量记录区的读取 (AV, ED, EU, etc.) BAR OL_CYLINDER OL_GAUGE PLOT with shape TREND XY plot 2. 图形中的条件语句: Simple expressions Compound expressions CASE expressions QUALITY expressions SET expressions 3. 利用条件语句组态动态图: COLOR TEXT SHAPE BLINK PROCESS_PT LINE_PAT SHAPE_PAT 4. 生成激活区( Poke Type ): Poke Type 0 Poke Type 9 条件语句 ? Simple Expressions(简单句) ? Compound Expressions(复合句) ? Case Expressions(Case语句) ? Quality Expressions(质量句) ? Set Expressions(Set语句) 简单条件语句 Syntax: (operand1 rel_op operand2) [ logic_op (operand1 rel_op operand2) ... ] Examples: COLOR FG cyan (A100 AV 50) yellow COLOR FG red ((A100 AV 50) AND (A100 1W = HDWRFAIL) OR (D200 = ALARM)) blue 参数: A100 AV = 10 SET2 = 20 A200 LL 100.45 A100 AS = ALARM D200 DS = RESET A100 RT = LA D200 RT = LD Set5 50 Set20 = A100 GS A100 AV $CONST1 复合条件语句 Syntax: { simple_expression1 conditional_value1 simple_expression2 conditional_value2 ... simple_expressionN conditional_valueN } Examples: COLOR FG magenta {(A100 AV 50) blue (A100 1W = HDWRFAIL) red} BG white Case条件语句 Syntax: (CASE) pt_name rec_fld initial_val increment count cond_val Example: COLOR FG magenta (CASE) A100 AV 1 2 3 green blue red if A100 3 magenta if 3 = A100 5 green if 5 = A100 7 blue if 7 = A100 9 red if A100 = 9 ma
