DL PLC QUERY
DL PLC QUERY
(OP)
I have migrated over from the motor controls forum to get some insight on DL micro PLC's.
I am product hunting and having a bit of trouble choosing between the DL205 and the DL405. I have seen the spec sheets and other threads but need to know the practical and fundamental differneces between them...
I am going PLC + OIT route and have chosen the EZ touch primarily due to driver support. Some of my issues are:
a. choosing relevant part numbers for the application
b. compatability
c. sofware support
d. opitons
Say I have 16 each of AO,AI,DO,DI, what would be the process of choosing part numbers to support this?

RE: DL PLC QUERY
Most of the I/O modules that for 405 series are avialable for the 205 series (the general use ones). If the 205 can satisfy your need you gain 1) price difference 2) space saving. However it is not always the case specially for big systems.
Start with your requirement.
-I.e state what is your I/O (quantity & type)you may find that your I/O is not aviable in certain PLC.
-state your peripherals you may interface with (serial coms, printers etc...
- what is the programming capabilities you are looking for (does it include real number, etc. some instructions are available for certain CPU only.
- Does scan time matter!
and so on state all your needs and constrains.
Then see if you can satisfy the needs with the following:
1- series 205 2) series 305 and 405
The reason for including 305 that in some cases the system build in 305 is cheaper than both 405 and 205. for small size projects 205 is best for bigger system 405 much suitable
Each PLC has its pros and cons. Also do not forget that in each you have a good selection of CPU power.
For your I/O count
This is general selection only (no power supply checked etc…)
D2-250-1 @249$
D2-09B-1 @180
D2-16ND3-2 @ 78
D2-16TD1-2 @81
F2-08AD1 @233 (x2)
F2-08DA1 @289 (x2)
D2-FILL @7 (x2)
Total 1646$
D4-440 @518
D4-RAM-1 @97
D4-04B-1 @103
D4-16ND2 @93
D4-16TD1 @115
F4-AD1 @516
F4-16DA1 @580
Total 2022$
As you can see one module in D4 can handel 16 analog I/O vers 8 only in the D2.
you can install max 8 modules in one D4 base but for D3 you can have up to 9 modules
$ value is not the correct way to select a PLC, if the 205 satisfy your need go for it if not drop it.
what I do is state my requirments and constrains and size a complete system from all avilable PLC (D4, D3, D2 etc)
Hope that this clear it a bit
if you have specific question just ask.

RE: DL PLC QUERY
the most I like about the 440 and 450 that I can have the memory cartirdge in my bocket, plug it in and the modification is done. In this regard the UV is very useful to prevent field program modifications!!
I build a system with full redundant scheme for more than 600 I/O and I found that the 405 is more suitable.
Another point: if you build panels for clients; FOR SOME SITUATION, some client would like to see some thing BIG in the panel and they compare the AB PLC size to the small 205!! So each application is kind of unique.
RE: DL PLC QUERY
D2-09B-1: 9 slot base, local I/O expandable. This is what I start with which means there are 9 slots that can accept 9 modules one of which would be the cpu. Voltage 110/220VAC
D2-250-1: cpu that would reside in 1st slot of base above. Why the D2-250-1 cpu and not say a D2-260?
D2-16ND3-2: 16 point DC input module
D2-16TD1-2: 16 point DC output module. What would be a practical example of using this module?
F2-08AD1: 8 channel analog input module Isn't this operated @24VDC? How would this reside in the base stated above? Would a D2-09BDC1-1 be used intead?
F2-08DA1: 8 channel analog input module. Sink or source output configurable
* What is win PLC
* What about PC-PGM-205 and D2-DSCBL for the programming aspect with DirectSoft32?
Are manuals included in the purchase of the various modules? For example for the modules listed above are the following manuals provided: D2-ANLG-M, D2-INST-M, D2-USER-M
This is quite alot to start with so I will reserve my ethernet questions until the next time..........

Browsing thru the site I seemed to have answered most of my initial questions. I guess I should have spent more time dowloading and reading those manuals before I started the thread. Anyhow I feel much more comfortable with the hardware side of things.
In terms of software, I have downloaded demo versions of DirectSoft 32 and EZTOUCH-EDIT. Are these tools the most effective way of programming the PLC and OIT respectively...............................
If not what is the preferred tool by consensus..I am a bit curious about how tedious the software aspect will be..
RE: DL PLC QUERY
I don't want to sound flip; but, unless you sure nuf have a large application, I imagine you can do it all it 1 day or 2 at the most, unless PLC programming is brand new to you.
Anyone here can help you with any technical questions about development and you'll be in good hands.
RE: DL PLC QUERY
You will be hearing on project progress as soon as it gets off the ground....
RE: DL PLC QUERY
Could this be achieved directly by PLC to printer without the PC interface? I would imagine so...
I was thinking of the PC for archival purposes. Maybe 3 months down the road a person would like to see process data for a particular batch...Does this make sense?
RE: DL PLC QUERY
Estimate the memory needed for your report data and memory locations needed for the program usage and see if the 205 variable memories can satisfy this. (not the program size)
Dumping the data into PC is more practical but only if the project is not overburden.
See also their DDE package that allows you to communicate with the 205 with EXCEL or VB.
If you plan to work with AD PLCs I would recommend to buy the full version of Directsoft, the reason is simple: you will have a feeling of other CPUs capabilities even without buying them, you can experience the differences in instructions.
If you will be connected to PC all the time, think of PC control also.
The options are unlimited; it depend on what you want to build, at what cost and your future plans.
Good Luck.

If I am going to buy a $3000 15" EZtouch panel why not get the LOOKOUT DIRECT PACKAGE. It seems that it will handle all I require and more..(datalogging, trending, historizing, report generation..) and even seems a whole lot eaiser, doesn't it?
Not too late though. Anyway how has it worked for you? What kind of support would I need apart from a PC?
I guess the following would suffice: PC-LKD-DEV, PC-LKD-RTE and PC-DL-PLUS..........................................
