Introduction

Data in Idec Micro PLCs is stored in different locations depending on the intended use of the data. For example there are separate locations for I/O, Timer Values, Data Registers and so on.

The Idec Micro PLC Data Address Format is a string that defines the location of data in an Idec Micro PLC. It consists of device type letters, followed by four decimal digits:
