I have another problem that I can not find the information/answer for. I looked in the manuals and at the Siemens site, and done every Google I could think to write. But alas, no guidance.
We have over 80 Durant Totalizers, model #57601-401, that we use to count parts made. We run at least three of these per line for redundancy. Due to some recent events management now wants to know if they can get this information without it having to be taken down by hand at the end of every shift/day. Stupid me says I think that should be possible, one of the reasons my mouth out ran my brain was I thought this is the perfect vehicle to get them to fork over the funding for a SCADA package. I have been learning how to transfer data through the 2572A card thanks to guidance from this site.
The Durant Totalizers use the ASCII code with the RS485 specification, this got my attention as I send messages to a marquee in ASCII. According to the Durant manual the Totalizers can be addressed 0-99 for polling reasons and the Totalizer will respond with what information you are requesting. All sounded just great and fairly easy to do until I tried to find out how to send/recieve messages from port 2 on the 545-1101/2/4/5. I figured this would be the correct port since it can be configured for RS485 by dipswitch #1 set to the right according to the manual (I really have been reading the manual before I had to ask you guys. I always feel like an idiot when you guys have the answers so seemingly easy).
So I ask, is there a way to program two-way communication through port 2?
Next, from the information I have given, is there a better way to do this? I have an un-used BASIC Module (505-7101) and read a little on these and wondered if this would be a better option. If there is different card that I could/should use, please mention it, there might be one laying around this place.
Thanks for taking the time to read this and thanks for any replies!
