Operands in a Control System Flowchart

The operands in a control system flowchart are placed in "margin bars" (with the exception of
connectors, which may also be placed in the logic field).
The following operands are allowed in a control system flowchart's input bar:
• IP 265 inputs
• Input parameters
• Connectors
• Constants
The following operands are permitted in a control system flowchart's output bar:
• IP 265 outputs
• Output parameters
• Connectors
Input and output parameters enable communication between the IP 265 user program and the CPU
user program. You will find detailed information on the interchange of parameters between CPU and
IP 265 in the manual in Section 4.3.3 "Parameters of the IP 265 User Program" and in Section 6
"Control of the IP 265 by the CPU User Program".
The operands are written with direct or symbolic addresses (identifier) in the margin bars.
Note
In the control system flowchart, symbolic identifiers have the prefix "-", the exception
being the parameters. Direct and symbolic identifiers for input and output parameters in
a control system flowchart have the prefix "=".
In this Product Manual, symbolic operands are covered in detail in a separate section (i.e.
Section 9.4.2).
