Thanks for that, I'll see if i can apply that on Monday

Hi all, Can someone show me an example of an efficient way to manipulate data, Scenario; I need to capture a product [count] (no problem) and then move the total into a tag after a set time.(again ok). Lets say this tag is called [last_hours_total] and has a value of [7533], here is where I need a little help, when the next hour is up , yes you guessed it I need to move the [count] value into [last_hours_total] and move the value that was in [last_hours_total][7533], into [previous_hours_total] and so on... and so be able to present a record of production over, lets say 12 hours, on a HMI I dont have logix software on this PC so would appreciate an office compatable format, like .pdf or .doc Help much appreciated !!!

Thanks for that idea, I have had a look at Scooters BC2 and this could very well be the answer to get files in order on this site. Unfortunatly I have inherited a culture where Contractors have been allowed to come and go as they wish, and no set protocols for storage or changes to software.

I have various .apa files on the hard drive of my laptop. How can i be sure that I have the up to date or correct one when I want to edit a panel View page. Is there some way of varifying the apa with the mer.

No, anything reasonably priced,what would you recommend. resolution is not an issue and the operation is multi turn, my thought was to use an Incremental, do you agree,

I am using a compact logix processor with a 1769 HSC card and am unsure which encoders to buy. The application is for a shelf loading carousel system. Consider a ferris wheel with 50 cars for the first encoder, I will want to re zero the value when each car hits a datum point. The second encoder is on a drive which pushes product into the path of each car prior to the car arriving at the loading area. This is mechanically cammed and a motor drives continually in the same direction while an arm pushes product in and retracts to home in a continuous move. One further consideration is either drive could be inched slowly in reverse from time to time to escape a jam I would like to keep it simple and hopefully deal with just a numeric value each time Thanks

Yeah, thanks. I'll try this one tomorrow when I get to work. I did manage to upload the .mer but when I tryed to run it , it started Station up and after about 2 minutes of egg timing came up with some error about not enough memory !!. I didnt persue it though

I am wondering if there have been any recent developments in the fight to modify RS View 32 programs when I dont have the .apa file

I dont think its the SO DIM RAM, as the supplier offers 128, 256 or 512MB at approx £200, £400 and £800 respectively, after reading your reply I checked the Manufacturers part no. and it looks genuinely expensive when I google it. I don't mind paying good money for good gear but this looks like an AB rip off compact flash

Have had a compactflash card go down on a Panel View plus 700, looking for a replacement on RS there are regular makes like Fuji at around £10.00 for a 512MB or Allen Bradley at £800.00. Do I need to use the AB or can I format a standard one or something ???

Thanks to all, setting the subnet mask and IP did the trick. Your input is very much appreciated CH+

Thanks, Have set up IP on my laptop, Subnet mask 255.255.0.0, IP 190.190.191.99. Will try that this morning

what should my Laptop IP/TCP be set to

ping times out, I have no reason to doubt the IP address document that I found, I have also tried to add the driver and getting the big red x, ihave tried the HMI IP with the same results. Just to re itterate, there is a 5 way ethernet switch with the PLC and HMI plugged in (and this is where I am attempting to connect too)

Thanx for that I'll give that a go.
