Chapter 11 Motion Control in PR Mode
Arithmetic Operation PR Display
You can use arithmetic operations and statements in any PR command
(PR#1…PR#99). It is identified or indicated as ‘Statement’. When the condition
is fulfilled, an arrow pointing to the next PR command appears with a solid
line. If the condition is unfulfilled, an arrow pointing to the next PR appears
with a dotted line. You can choose to execute the next PR command and stop
once the execution is completed. See Figure 163
.
Figure 163 - Arithmetic Operation Display
1. Command execution type: an arithmetic operation command can
interrupt (INS) the previous PR command. If the Interrupt function is
enabled, it displays (I); if not, no information is displayed.
2. Statement number: displays the statement number used in the PR
command.
3. Execution time (Exe.Time): the time required to execute the arithmetic
operation.
Trigger Methods for PR
Commands
This section describes the four triggering methods for PR commands.
Digital Input (DI) Trigger
When you use PR Operation Mode, you can choose the PR command to be
executed by using Digital Inputs with a binary weighted equivalent values
(Register Position command Selection - Bit 0…Bit 6). Use DI Command
Triggered [0x08] to initiate the selected PR command.
See Description of Digital Input Functions
on page 433 for more information.
This can also be set in the Digital I/O and Jog Function dialog box in
KNX5100C software, as shown in Figure 164
.
