Info and Help with PLC and Programming

A Few questions for you guys.

Anyone have any input on the Array (FAB) Plc Controler
http://www.oceancontrols.com.au/plc/fab_plc.htm
Good, bad, or a OK unit ?

What im Planning,
Im Setting up a hobby green house for the other half and
want to use this plc for controling the greenhouse.
Turning on/off water pumps, fans, ect ..

My experiance is a AOS Degree in Electronics but have been out
of the field for a few years so im very rusty at this.

Here is the problem im working on now thats just has me baffled.
i need a cycle a water pump say 30 minutes on, 1 hour off

I got this to work but when i turn on the Input there is a 30 minute
delay before it starts working. what i want is when input 1 is on the
pump is on timed for 30 minutes, then goes off for 1 hour then repeat
the cycle.

[CPG] Clock Pulse Generator Details
Pin: ... Description

IN: --- Make clock pulse generator ON and OFF via Input EN Enable.

R: ---- Reset, Make Output Q be 0 via Input R

Output: --- Every time EN changes from 0 to 1, the internal timer
begins to time, and when Time T is up, the output is 1.
If EN is held on 1, timing can be started again, and when
Time T is up again, the output is 0. The cycle operation
is continued in this way until EN is 0 and Output Q is 0.
When R is 1, the output Q is 0. And when R changes from 1
to 0 and EN is 1, all the initial status of Q changing
from 0 to 1 will start its cycling change.

Like most members of the forum, I can say: Never heard of it!

It looks like another repackaged and private labled Moeller easy.

The specs look a lot like the Moeller units too.

The software is a little different, but then the A-B version is a little (LOT) from Moellers.

The networking of 256 units doesn't sound familiar.

Overall, I'd say stick with something domestic. Since almost every plc manufacturer is relabling Moellers (A-B really shocked some of us), I would stick with one of them.

I don't know what the exchange rate is. I can pick up a basic easy with a clock for about $125.

thanks for the reply.

The last plc i used was by A-B (ladder logic)

All the PLC's i looked at are just to pricy. 300.00 and up
and then you have to buy the software, add another 200 and up.

I came across this unit and found it for 100 bucks (US) and
the software is free. i said WOW. this just might do it.

AS Casey wrote I never heard about this name.
This smart relay divided to 2 groups .
1.programming with ladder diagram. Easy Pico or Zen.
2.programing with logic gates like Crouzet and others.Many others.
I guess logic gates is very cheap to manufacture.I saw many types from the far east.

It up to you, what you prefer.The familiar ladder or something unique.
About the price most of them it a same.

If you need sophisticated smrt relay with Modem,SMS,expansion I/O.
Crouzet will give you that and more.

look for Millenium 2

look also for DL05 of automation direct 100$

BTW ML1000 is about $100 and free software for that.
You will need cabel that about $50.

Yup, never heard of it myself either. I downloaded the program and played around with it. Very frustrating for a PLC programmer, but fun to play with logic gates once in a while...

Based on your what you're trying to do, here's what I came up with...

[attachment]

This makes the output cycle on and off indefinately (with separate on and off times), as long as the input #1 is ON, and input #2 os OFF.

Thanks for the replies guys,

I knew this could be done with 2 time delay realys.

Man i have been out of this field to long .. LOL
but it slowly comes back like riding a bike.
