ISPSoft User Manual

ISPSoft User Manual
The users can type a device name or a symbol in the box. If they type a symbol which is not
declared, the Add Symbol window will appear after they press Enter on the keyboard. (Please refer
to section 2.3.1 for more information about declaring a symbol.)
After users click a network and press Enter on the keyboard, they can edit a box. The users can edit
the next box in the network after they press Enter on the keyboard. Besides, the next network will be
selected after the users press Tab on the keyboard. The users can edit a box with the keyboard. If
the users have declared symbols, they can press Page Down on the keyboard when they edit a box.
The users can select a symbol by the up/down key on the keyboard. After the editing is complete,
the users can press Enter on the keyboard to jump to the next box. If the users want to end the
editing, they can press Esc on the keyboard.
Additional remark
(a) If users want to use constants in a function block diagram in ISPSoft, the constants must be
represented in the following ways.
‣ Decimal value: 23456 (A value which is not preceded by any mark will be regarded as a
decimal value.)
‣ Hexadecimal value: 16#5BA0 (A value is preceded by 16#.)
‣ Octal value: 8#55640 (A value is preceded by 8#.)
‣ Binary value: 2#101101110100000 (A value is preceded by 2#.)
‣ String: “XYZ” (Characters are put in double quotes.)
‣ Boolean value:
AH500: SM400 (normally-open contact), or SM401 (normally-closed contact) is used.
DVP: M1000 (normally-open contact), or M1001 (normally-closed contact) is used.
(b) If users want to use a symbol whose data type is ARRAY, the expression format is
Identifier[Index]. Generally speaking, an index is a decimal constant. The indexes in a function
block diagram can not be symbols. The minimum index value for a symbol whose data type is
ARRAY must be 0, and the maximum index value for a symbol whose data type is ARRAY can
not be larger than the number of elements in the array.
9.2.3 AND Block and OR Block
Contacts in a function block diagram can be connected in series/parallel by means of an AND/OR
block. The input nodes and the output nodes of an AND/OR block must represent Boolean devices
or symbols whose data types are BOOL. An AND/OR block have 32 input nodes and 32 output
nodes at most. Besides, an AND/OR block has at least one output node, or is connected to the next
object.
• Graphical representation
• Example
Example 1: The contacts M0, M1, and M2 are assigned to the OR block, and the result of the
operation is sent to M3. In other words, after M0, M1, and M2 are connected in
parallel, the coil M3 will be driven if M0, M1, or M2 is ON.
