A PIC, assuming that you are talking about a AB 1747-PIC, is a Personal computer interface converter. It is used to connect a computer to a SCL 500 AB PLC. Some of the processors didn't have a rs232 port and it was used mostly for hooking up a laptop to the PLC for program downloading and...

I am currently using a DH 485 network to link several plc together using ABKF2 driver for our wonderware application that is communication to all of the plc's. I am needing to change over to ab device net for my plc communications and will need a different driver for the device net to...

Turned out it was being caused by the Open TC detection scan. I disabled this and it is working fine now. Thanks djs and everyone else who took the time to give it some thought. I have used this forum several times and have yet to be dissappointed. Daymond

Oh yea, its a k type TC reading a temp of approx. 235 deg. C

When I say that they are parallel, I mean that we have one TC coming in to the prowers controller and it is daisychained over to the PLC. We have TC's daisy chained at other parts of the plant to several devices with out any trouble. We only use it for a lolo alarm and several degrees of...

I have several Powers 535 controllers controlling verious Processes using a k type thermocouple as the pv. I am needing to input these temp. signals into a AB 5,03 PLC. My plc is located close to the controllers so I just paralled the TC's over to a 1746-NT8 Thermocouple/mV Analog Input Module...

Thanks alot. I did get a macro wrote that would log the data on a time basis but I had not got the auto run working. This will be helpful and I am new to VB but I think I can fumble my way through making any changes that I need to make. Thanks again. Daymond

That sounds great. I will look into your advice on having wonderware create a historical data base.

I'm trying to do this all through excel. We do have wonderware poking some infomation into excel but it is a lot of data and already slows down the system everytime it does this (every 5 minutes). The formula I have in excel is very simple.It is VIEW|TAGNAME!b_fce3_CoolingValveOutput I was...

I have excel getting data from my wonderware program. Every time my data changes in wonderware it is updated in excel. My problem is that I have a formula in one cell to gather this data. Each time the value changes in my wonderware program it changes the value in that cell. What I am trying to...

Thanks for directing me to the proper forum. I will try inserting a new line above that one and recording a macro to do this every time. Daymond

Wondering if anyone uses excell to gather data from wonderware instead of using wonderware to write to excell? I have been told it can be done but have not ever seen it. If I remember right, excell and wonderware can either one be the client or server. I'm no expert in excell by any means and...

I got it working. Its wasn't that hard once I quit trying to use the network to set up th processor and used the laptop to get the node right. thank for all the help. Daymond

I am adding a plc 5/03 to an existing network that has 4 other plc's communication through a DH-485 communication interface. My plc's are adressed nodes 1-3, I have added a plc and it is now my first plc from the DH-485. Its the first one in the daisy chain. I thought when I added one it would...
