Productivity 1000 Series PLC Drum Sequencer Instructions

The productivity series of PLCs has a Drum and Sequencer instruction.
Drum instructions are great tools. They mimic an electromagnetically drum sequencer. Have you ever seen the mechanisms of a music box? Ok so it’s a little drum with pegs that catch and flick the chimes in a particular sequence to play whatever tune is on the drum. So in the PLC you can have a drum driven by an event, (input from a limit switch or button), or by time.

Sequencers are similar to the drum instruction. The sequencer output can have up to 16 Boolean, Integer or Numerical Tags per step. Drum instruction outputs are limited to the same 16 bit (Boolean) outputs. Each step in the sequencer can be defined by time or /and event and specified outputs can be set going into and out of the step.
We have done similar Drum instructions for the BRX Series PLC and the Click PLC.

We will be discussing the drum and sequencer instructions in the Productivity Series PLC. Simple examples will be done to demonstrate the power of these instructions. Let’s get started. Continue Reading!

C-More Micro HMI Object Numeric Entry

The C-More Micro HMI Panel software uses virtual components called Objects. These objects are programmable to simulate the functions that you require on your automation project. Several of these objects can be placed on one panel screen and you can have multiple panel screens. This helps you produce simple, intuitive looking human machine interfaces.

Continuing from last time we will now look at the numeric entries that we can use with our HMI micro panel. Let’s get started. Continue Reading!

C-More Micro HMI Object Buttons and Indicators

The C-More Micro HMI Panel software uses virtual components called Objects. These objects are programmable to simulate the functions that you require on your automation project. Several of these objects can be placed on one panel screen and you can have multiple panel screens. This helps you produce simple, intuitive looking human machine interfaces.

Productivity 1000 Series PLC Array Functions Part 3

An array is a storage area for a group of common data type tags. They usually have some relationship to each other and need to be manipulated as a group.

Previously we defined an array and use this in an indirect addressing program. It sequenced bits in an output card indirectly. We then looked at the following instructions: Array Statistics (STA), Copy Array (CPA), Fill Array (FLA) and Shift / Rotate Array (SRA). We will now look at the final four array instructions:
Pack Boolean Array (PBA) – Pack an Array of Boolean tags into a destination Word Array
Pack Word Array (PWA) – Convert one 8 bit or 16 bit array into a 16 or 32 bit Destination Array tag.
UnPack Boolean Array (UPBA) – Unpack an Array of Word tags into a destination Boolean Array.
UnPack Word Array (UPWA) – Convert one 32 or 16 bit array source tag into four 8 or 16 bit array tags.
Let’s get started with our final look at arrays in our Productivity 1000 Series PLC. Continue Reading!

C-More Micro HMI Object List Shapes

The C-More Micro HMI Panel software uses virtual components called Objects. These objects are programmable to simulate the functions that you require on your automation project. Pushbuttons, switches, meters and graphs are just a few of the objects that are available to you.

We can place several of these objects on one panel screen and have multiple panel screens. This helps you produce simple, intuitive looking human machine interfaces.
We will be looking at our program we have so far developed (Simulate Project) and add shapes to our blank page. The navigation of the objects and additional information will also be discussed. Let’s get started. Continue Reading!

Productivity 1000 Series PLC Array Functions Part 2

An array is a storage area for a group of common data type tags. They usually have some relationship to each other and need to be manipulated as a group.
Last time we defined an array and use this in an indirect addressing program. It sequenced bits in an output card indirectly. In this second part we will be looking at the following instructions:
Array Statistics (STA) – This will perform operations such as Summing, Averaging, Minimum Value and Median Value on an Array.
Copy Array (CPA) – Copy a block of 1 or 2 dimensional arrays into a destination array.
Fill Array (FLA) – Copy a value to a block of array elements
Shift / Rotate Array (SRA) – Concurrently Shift or Rotate values in an Array.
Let’s get started with the Productivity 1000 Series PLC arrays part 2. Continue Reading!

C-More Micro HMI Simulate Project

The C-More Micro HMI Panel software has a simulation mode. This simulator will allow you to test your project before transferring it to a panel. Testing your application is a vital step in HMI program development. This feature of the software will save you time and money especially if your hardware is not available.
The simulator will display two windows. There is a graphical display of your HMI panel and a simulation control window. The control window will allow you to control variables in the project similar to a PLC.

We will be looking at our program developed last time (Common Control Menu) and use the simulator to mimic how the PLC and HMI Panel will communicate in the field. This will help to detect any problems before we transfer to our panel. Let’s get started. Continue Reading!

Productivity 1000 Series PLC Array Functions Part 1

An array is a storage area for a group of common data type tags. They usually have some relationship to each other and need to be manipulated as a group. We can use arrays for motion control, recipe management, sequencing (indirect addressing), math, etc. The Productivity 1000 Series PLC uses arrays which are programmed using the Productivity Suite Software.

We will be defining an array and use this in an indirect addressing program. This will sequence bits in an output card indirectly.
Let’s get started with the Productivity 1000 Series PLC arrays. Continue Reading!

C-More Micro HMI Common Screen Menu

Allowing operators of your HMI (Human Machine Interface) panel to easily navigate all of the information available is a vital part of programming. We want to present the information to the operator so they will clearly understand the programmed operation of the unit. Common menus on the HMI panel pages will allow the quick navigation, understanding and control that your operators want. When programming operator interfaces I have always heard to use the KISS method. (Keep it stupidly simple.) Your HMI program interface could contain hundreds of pages containing vital information for operator understanding and control, but you must make it easily accessible and intuitive. This is how you design and program a good HMI panel display.

We will be creating a common screen menu for our C-More Micro HMI Panel using the C-More Micro programming software. Using our previous program created we will be making a background screen to act as our menu system. Let’s get started. Continue Reading!

Productivity 1000 Series PLC Data Handling Instructions Part 2

Data handling instructions are used to perform movement and manipulations of the memory in the programmable logic controller. The Productivity 1000 Series PLC has fifteen different data handling instructions that can be used in a wide variety of applications. In this second part we will be looking at the following instructions:
Lookup Table (LKUP) – Find a value within an XY Table by looking at the intercept of a referenced X Axis value and Y Axis value.
Pack Bits (PKB) – Convert up to 32 Boolean Tag Bits or Constant Bits into an Output Integer Tag.
Pack Word (PKW) – Convert up to four 8 bit tags or two 16 bit tags, or four Constants into a 16 or 32 bit Destination Tag.
Shift / Rotate Bits (SFR) – Shift or Rotate Bits of a Tag or Constant value.
Sign Magnitude (SMAG) – Convert Sign Plus Magnitude data type values to 2’s Complement or Convert 2’s Complement data type values to Sign Plus Magnitude.
UnPack Bits (UPKB) – Convert up to a 32 Bit Integer Tag or Constant into Boolean Tags.
UnPack Word (UPKW) – Convert one 32 bit or 16 bit source tag into four 8 bit tags or two 16 bit tags.
A review of data handling instructions part 1 can be found here. Here is a link to the video.
