We are designing a telemetry system for a water plant and the systems utilizes various style water tanks. On our electrical drawings we would like to show a general picture of the water tank to show how the antennas are mounted. Does anyone know where we could download a couple of example...
I have two Machines say a moxel x and a model y
the PLC programs used in both are the same but the machines are diffrent sizes, the motor sizes and options are diffrent.
I have it set-up that all of the model spec's reside in F8 data.
when I download a program from model x via my laptop into...
I know that none of the HMI are of the touch type all have keypads, but the end customer would not go for applying a protective film over the displays. The end customer has seen these on a competitor’s equipment, and is dead-set on the displays being totally covered and lockable.
A touch...
Hello everyone
I have an OEM for whom we integrate their equipment lines coming into the US from Europe. Due to some of the environment and chemicals involved it has been request that we add a protective cover to the PanelView 600 plus displays.
Application:
Mutil- PanelView 600 and 600+
What...
I'm sure everyone has seen the access terminals that are on the mounted on the outside of an enclosure (NEMA 12 or 4 with Flip top cover) which allow you to plug in a laptop to 120VAC and has an other plugs for connecting to a network without opening the enclosure.
I have looked everywhere and...
As far as I know you cannot extract from an ST and move the value directly to a floating-point number.
I'm using an AEX and moving what I need to another ST word then converting the characters into an Integer with an ACI
Hey !!!! :-0 :-) I just figure it out thanks to your help
1 : - 0 0 0...
The string is in ASCII
I have another computer setup and monitoring the data as it comes into the MVI46-GSC card serial port via Hyper-Terminal. It is raw and before it is placed in the M0 area of memory then moved to the processor into a ST:
An exact example of what I see is...
I made a mistake it appears that converting a + or - to an integer does not return a value of 3356 and I had thought a : equaled 3320. I'm unsure of where or how I came up with these values. After testing more placing a text value of + in a text string and sending it to a integer returns no...
I have a project, which utilizes an MVI46-GSC that is basically a RS232 serial communications card. (RSLogic, SLC505 Processor) I'm receiving data from a multiplexer, which communicates to up to 4 other field devices. The multiplexer in only capable of sending the information in an ASCI format...
I have recently purchased a copy of Terrain Navigator 2001 and plan to use it to locate telemetry project sites. I probably should have asked for a recommendation here first but it's in the mail and should have it Monday. I selected the software for it's 3D effects and download ability of...
Does anyone know where I can find a Manual (on-line) for an old Fischer Porter Flow Meter Model 50US-3113ABB The meter is old but the customer wants it calibrate. ABB purchase Fischer Porter but no manuals to cover this model.
I hate to tell the customer "I can't help unless you buy a new...
After 4 days of work I have completed this part of the logic for the equipment. It only required 14 rungs of logic but I'll have to say, it is more complicated that one would think due to having to evaluate both the AP and DP thur the 51-1 point.
In order to keep the math straight I gave each...
I have been working for a couple of days to develop a PLC scheme. And I just can not work it out, the math is simple but has to change and it's hard to keep up with. Maybe some one can Help (or I maybe over complicating the scheme and re-inventing the wheel) This logic will coincide with other...
It would seam that if I could keep the pump running to maintain the level. There would not be as many start cycles and the second pump would not need to come on to assist in meeting the High demands. Them the utility peak would be lower for the month.
The system works off of a 3 min delayed...
An Application utilizes two pumps to fill a water tower. When the water level reaches the lower setpoint the first pump starts and runs until the high setpoint is reached at which the pump is stopped. (Just a typical pumping scenario.)
The cycle of the pumps appear to be a runtime of about 30...
I have done several projects of this type. In all cases the customer already had decided what PLC they wanted to use or were already using.
One project had 35 pump stations and 10 metering stations with a Main control center that gathers data and alarms and issues pages and cell messages to the...
I survived the prototype phase of the project. The drawings at this point are about 600 pages of 11x17. I ended up creating my own AutoCAD block based on the IEEE and IEC standards, but I still had to create some unique ones.
dpc's statement is also very true "My only advice is to make...
Has any one seen a chart, download, or website that shows a comparison of American and European Electrical Symbols? (I have looked almost everywhere) I have also searched the AutoCAD site, but it does not have what I'm looking for.
I have taken on a very large control design project and the...
