T4 - TIMER - Is a data type made just for the timer instructions and are made up of 3 integers organized so you can access parts of it as bits and parts of it as words. For how these bits are organized into other data types see the N7 - INTEGER below. All other data types are made up of combinations of binary bits. Your discrete inputs and outputs are binary bit address. Note that many times where the word is always 0, it will be omitted and stated as I:0/0.ī3 - BINARY - Are the most basic storage location that can either have a value of 0 or 1. 0/0 through 0/15 are the first 16 inputs of the slot, 1/0 through 1/15 are outputs 16-31 of the slot, etc.ĭiscrete inputs on the base PLC I:0.0/0 through I:0.0/9. If this is an analog module then 0 is the first channel, 1 is the second channel, etc.ī is the bit and is used for discrete inputs in combination with the slot. We'll go more into detail of what a word is in the N7 explanation below but for discrete inputs, 0 is outputs 0-15 of the slot, 1 is inputs 16-32 of the slot. 0 being the PLC base's built in inputs and 1 being the first expansion module, 2 being the second expansion module, etc.

I1 - INPUT - Stores the state of the PLC inputs. Note that many times where the word is always 0, it will be omitted and stated as O:0/0.Īnalog outputs on slot 1 O:1.0 and O:1.1.

0/0 through 0/15 are the first 16 outputs of the slot, 1/0 through 1/15 are outputs 16-31 of the slot, etc.Įxamples of outputs used on your trainer:ĭiscrete outputs on the base PLC O:0.0/0 through O:0.0/5. If this is an analog module then 0 is the first channel, 1 is the second channel, etc.ī is the bit and is used for discrete outputs in combination with the slot. We'll go more into detail of what a word is in the N7 explanation below but for discrete outputs, 0 is outputs 0-15 of the slot, 1 is outputs 16-32 of the slot. 0 being the PLC base's built in outputs and 1 being the first expansion module, 2 being the second expansion module, etc. O0 - OUTPUT - Stores the state of the PLC outputs. The data files are a way of organizing and optimizing the data storage in a PLC.
