Programming the IP 265 with COM 265
Note
The "Store" key (<F6>) must be pressed each time modifications are made in the list,
also after delete and copy.
The purpose of the IP 265 assignment list is illustrated below, using the initialization of timers as an
example.
Example: Initializing timers
Invoke the local operand assignment list (if not already done)
Make some entries in the list. Assign the symbolic identifier of the Preset value to the direct
address of an input word parameter, e.g.:
IW 66 TIMER
Press <F6> "Store" to store the operand reference.
Exit the symbols editor with <F8> "Return".
Call the editor in the COM 265 top menu with <F1> "Editor".
Position the cursor in the IP 265 user program to the input field for the timer's Preset value (TV).
Activate the input mode with < 1 >.
Enter the symbolic identifier referenced in the operand assignment list with the prefix "=", then
enter the time base (without pressing < 1 > first!), e.g.=TIMER.1
Terminate input with < 1 > or <INSERT>.
Additional information on the IP 265 assignment list:
Note
• If you assigned a symbolic address to an operand in the operand assignment list,
COM 265 will always display the operand's symbolic address in the control system
flowchart's margin bars.
• A symbolic identifier and operand commentary, once defined, may be overwritten
as often as desired in the operand assignment list.
• You can generate individual operand references or resolve and redefine existing
operand references in the operand assignment list quickly and easily whenever
necessary.
• The operand assignment list can be corrected before, during or after editing of the
control system flowchart.
The last entries must be made in the list, at the latest, before compiling the control
system flowchart.
• COM 265 automatically stores all addresses specified in the control system
flowchart (whether direct or symbolic) in the operand assignment list.
• Direct identifiers used in the control system flowchart cannot be deleted from the
operand assignment list.
