Basic Demonstrations 4-1
MN1917
4.1 Introduction
This section demonstrates the basic controls and introduces the PLC Task and Presets modes.
During some tests there may be a small delay before WorkBench v5 responds to control panel input. This is not caused
by the Flex+Drive
II
, but is a deliberate system refresh delay built in to WorkBench v5. To adjust the refresh rate, choose
Tools, Options from the menu and select the System tab. Using short delays will improve WorkBench v5’s response, but
will reduce the performance of other applications running on the PC.
4.1.1 Basic controls - input switches
The Flex+Drive
II
has a minimum of 8 digital inputs accessed on connector X3 pins 10 to 17.
On the demonstration unit, switches 0 - 7 on the control panel are already wired to this connector, so they can be
used to simulate digital inputs.
1. In the WorkBench v5 toolbox, click Application then
click the Edit & Debug icon. This will ensure that the
Spy window is displayed.
2. At the bottom of the Spy window, click the I/O tab.
This will display virtual LEDs indicating the state of
the digital inputs (and outputs).
3. Operate the control panel input switches. The corresponding Spy window LEDs will show the inputs being
recognized by the Flex+Drive
II
.
4.1.2 Basic controls - output LEDs
The Flex+Drive
II
has 3 digital outputs available on connector X3 pins 18 to 20. Output LEDs 0 - 2 on the control
panel show active digital outputs.
1. If Edit & Debug mode is not already selected, in the
WorkBench v5 toolbox click Application then click
the Edit & Debug icon. This will ensure that the Spy
window is displayed.
2. At the bottom of the Spy window, click the I/O tab.
This will display virtual LEDs indicating the state of
the digital outputs (and inputs).
