B–2 DL105/DL205/DL350/DL405 Application Example

In this manual a Cement Kiln System is the model for demonstrating the ladder logic

required to support the various OP-panel features. The programs provide ladder

logic which demonstrates controlling pushbuttons, lamps, messages and menu

operations.

Items listed in the figure below such as Hopper Selection, Kiln Speed,

Start/Stop/Run controls, and Kiln Zone Temperatures are monitored and controlled

by the OP-panel example programs.

These example programs and additional technical support information may be

accessed on PLC

Direct

’s worldwide web site:

http:\\www.plcdirect.com (website for general info/file transfers)

You may also find these programs on our 24-hour per day BBS system at:

770–844–4209

Direct

LOGIC and Compatible Example Program

The example program listed on the following pages is designed for

Direct

LOGIC

DL105, DL205, DL350, and DL405 PLC systems. The program supports the

OP–1510 Kiln Demo program.This program is included on the 3 1/2 disk labeled

“OP-1500/OP-1510 Example Disk” which is provided with this manual.

This example program (1510_105.PRJ) must be used with the OP–1510

configuration file 1510_105.OCF. Load these program files to the PLC and OP-panel

for connection and operation of the Kiln Demo application. You may also refer to the

Appendix A “Example Worksheets” to help understand how the OP-panel is

configured.

This program is designed to be used with the

Direct

Logic DL105, DL205, DL350,

and DL405 PLC and compatible systems. The following program is intended for

training purposes and

may not

resolve all possible OP-panel applications. Some

PLC programming knowledge is required to fully understand and implement the

following program examples.

If the CPU power cycles or machine and operator conditions are idle, this rung will

initialize OP-panel and display message #1 and message #2.

Memory Mapping

This rung is necessary for all

Direct

LOGIC CPUs which

do not

support bit-of-word

instructions. Mapping the Status and Control registers into Internal Control Relays is

necessary to have bit level access to this data. The Status and Control register bits

are used to monitor pushbuttons, control lamps, and perform asynchronous data

exchange between the OP-panel and PLC.
