You can add a remote PLC slave rack of productivity 1000 series modules using a P1-RX. Up to 4 remote I/O base controllers can be added to the P1000 system.
We will be updating our P1-540 CPU unit to a P1-550 CPU in order to take advantage of remote IO. A P1-RX remote IO-based controller will be added and configured. Let’s get started. Keep on Reading!
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 first part we will be looking at the following instructions:
Absolute Encoder (ABSE) – Encoder input using Gray Code or Binary Code
Compare Values (CMPV) – Compare two different tags and determine if equal, greater than, or less than.
Copy Data (CPD) – Copy tags from one location and place them in another.
FIFO / LIFO (FILI) – First in first out / Last in first out
First Bit On/Off (FIB) – Determines first bit on in a series of bit tags.
Inc / Dec (INC) – Increment or decrement a tag by a number.
Logical Bits (LOG) – Perform logical operations on Boolean input tags.
Logical Words (LOGW) – Perform logical operations on tags.
In part 2 of data handling, we will continue with additional data handling instructions.
Let’s get started with the Productivity 1000 Series PLC data handling instructions. Continue Reading!
