When my company moved from VAX or PLC based systems to PC based automation, we carried some legacy hardware with us. For e.g. we still use a (microcontroller) based temperature controller and the PC communicates with it setting and
reading some parameters. I want to change the way this works in our company and use the PC itself for controlling the temperature. Most of our equipment needs a A/D and D/A cards and I could use an unused channel for interfacing.
My question to the community is wheter anybody has done this and if yes, are there any potential problems? I am confident, but I would be glad to forward your comments to my department for approving me to go ahead with the project.
Currently we use VC++ 5.0; NT 4-SP3 and the platform is a Intel pentium industrial computer with 256 KB RAM. Our scan time is 10ms which is not to be sacrificed.
Thank you for your inputs,
