GE Fanuc Series One PLC

[Lesleh]

I just purchased a Brown and Sharpe surface grinder with a GE Fanuc Series One PLC and cannot get the machine to run correctly

I have the ladder drawings and thru those I determined which output should be activating the solnoind I want

Here is my problem the ( Output )PLC card lights up on the correct terminal BUT there is no voltage at the wire terminal, I switched out the card with one I just purchased as tested and good with the same results

I am not a PLC expert just a machine shop guy trying to make a living, I cannot find anyone in the Pittsbugh PA area who seems to have knowledge of this PLC

Any help would be appreciated

So do you have correct power source for the solenoid running to the PLC output? The LED is probably running off the PLC power supply. It's telling you the output contact is closed. But there may not be any voltage across the output contacts.

The PLC output is just a contact. You've got to power it up to do anything with it.

Lesleh,

The following excerpt from

http://web1.automationdirect.com/ad...standard&OVADID=5035173022&OVKWID=28928683022

says it all.


" This PLC design has been marketed by various name-brand PLC manufacturers for over 20 years. It has masqueraded as the General Electric Series One, the Texas Instruments Series 305, and the Siemens SIMATIC TI305.

DL305 PLC features include:

* Four standard CPUs to choose from, including the D3-350, with PID control and two communication ports
* Standard CPUs programmed with handheld programmer or Windows-based software
* Specialty CPUs convert a DL305 system into an RTU for Optomux, Pamux, or allow BASIC programming for custom applications
* Five, eight, and 10-slot bases
* 110/ 220 VAC or 24 VDC power supply
* AC, DC inputs
* AC, DC, and relay outputs
* Eight or 12-bit analog input/output
* Specialty modules include an ASCII/ BASIC module, high speed counter, and communication interface module"





Finding some local expertise shouldn't be at all difficult.

The name GE/Fanuc may be confusing to some however, as GE is a name not to be trusted. Remember that GE (General Electric as opposed to Good Enough) is a company started by a man credited with inventing the lightbulb, and now is a leasing company that also produces jet engines and locomotive traction engines. Their name and logo are used by all sorts of companies, making or marketing all sorts of items, that have paid big money to use that name.

HCBFlash,

I have no connection with GE and have no love for them, but your assertion that it is a name "not to be trusted" is a bit over the top. GE actually owns all the companies you are talking about. Like most multi-national corporation, they do some things well, some things not so well and often their left hand and right hand do not communicate. But they still have some decent, useful products.
