Is there any way I can get more than 24 characters into the symbol name on a S7416-2DP?I am using Simatic Step 7. Thanks in advance.

I am attempting to write a loss in weight program for feeding powdered material at a steady rate by user setpoint. I think I have confused myself and was wondering if anyone would mind checking out Ladder 8 of this program to see if I am on the right track or have just made a mess and need to start over. Any help or hints will be greatly appreciated. LOSS_IN_WEIGHT_TEST.RSS

Thank both of you very much for the speedy response and good info oh, probably an s7-400

I am thinking of trying to integrate some Siemen s7 PLC's into the location I work at and was wondering if there is a demo of the development software so I could get a handle on the programming of them. To make sure they are what I want to go with. Does anyone know where a demo copy of the software would be available I can not locate it on their website. Thanks.

I have always labeled the IO cards on the print 1,2,3,4 etc. and added the address to it slot 1 output 0 would be wire number 100. All of my DC is 50 - 99. AC misc and control is x1,x2,1-49. Hope this helpsand doesn't sound to silly.

I am using a Micrologix 1100 and a panelview 1000 2711-k10g20. Both are ethernet and i have updated my ab software but am unsure of what to select for the node in comms setup. The ML 1100 is not listed. Any help would be appreciated. Thanks.

I was digging through some storage boxes at work and found severl old Omron Sysmac c200h, C60k, and C28k PLC's. I was wondering if anyone knows what software and cables I would need to program these, and where I could find some more information on them. I am having trouble finding anything on the omron247 website. Thanks in advance.

I just tried the multiply and divide method that Ken Moore explained. It seems to be working ok, I am performing linearity and repeatability tests right now to see if it will pass Handbook 44. I would have rather used an onscreen button for print so I could use the pilot on the pushbutton but the recurring problem we have had with retail batch indicators is the operator pushing buttons with anything but their fingers so the pushbutton for print, zero, and tare are standard 800f pushbuttons. Thank you both for all your help.

I am using the 50 mV scale on a tc card to read a load cell. The value is read in raw/proportional and scaled across an scp with calibration values to check weights. The problem I was having was the Panel View would show 44.3 lbs which made it in the acceptable range for the operator to print. The problem with that was the panelview showing 44.3 and the plc actually has 44.2875 or something similar that would round up to 44.3 on the panelview. So the operator is pushing the print button at an acceptable weight and the plc is setting an intgeger to tell the operator thru the panelview that it is not acceptable.

It is rounding up the 1 decimal place on the panelview and making it different than the actual PLC. 44.297 shows up as 44.3 on the panelview. I need it to be the same on both so when the operator pushes enter the PLC doesn't reject when the panelview says it is right.

I need to change a floting point number from 44.3087 to 44.3. I have seen this on the forum before but can't find it again. I am also going to need to display it onto a panelview so I would need to know what integer the 44 and the 3 would be in. Thanks in advance for any help. I am using the SLC 5/04 processor

I am using a SLC 5/04 with a thermocuple card to read mV from the junction box on a floor scale. I am having trouble maintaining the proper zero after I do a calibration. It seems that the scale floats. I am planning on purchasing and installing a Hardy 1746-WS weigh module but was wondering if anyone has ever succesfully used the thermocouple card method for a scale, and if there are any options other than the Hardy module?

I can use a cable that is for dh485 I think. I have had to use it before. I usually connect my laptop thru DH+ ch1. I am trying to connect ch0 to a pc by serial port using Winwedge to capture everything into excel and notepad. I have ch0 system set to shutdown and ch0 user set to ASCII 9600 8,n,1.

I am setting up a SLC 5/04 with a PV 600 connected across DH+ as a batch weighing system. I have written the program with all of the AWA and AWT commands and would like to test it before installing on the floor. I read somewhere on here that I can do this through Hyperterminal but I can not get it to connect. Could someone tell me what cable I need and if I have to have an open port or handshake command in my program to do this? Any help will be appreciated and a lot will be appreciated more.

Thanks, never even though of moving the s files to an integer.
