Warren Postma's Embedded Systems Development Projects embed@geocities.com   Things I am currently working on at ZTR Control Systems.

NEWGEN Remote Monitoring Kernel: An embedded driver written with Borland C++.  Runs on an Octagon 6012, 6040 or 4000 CPU which have Datalight Systems ROM-DOS in ROM.  The systems have no video card,hard drive or floppy drive.  In a 100K program it monitors analog and digital inputs, sends numeric and alphanumeric pages out when alarm conditions occur.  With the addition of a voice modem, it can be used to send out digitally recorded voice alarms, and you can dial in and listen to the alarms and acknowledge them as well.  It can historically trend analog points. It's data storage is provided by SRAM and FLASH chips. These are mapped by ROM-DOS to look like regular disk drives (drives C:, D:, and E:) just like in DOS. There is 128K of battery backed SRAM memory (small but quickly rewriteable) and 512K to 1MB of Flash memory (rewriteable up to 10,000 times, and slower). These systems can also have Cellular modems if no phone line is available.

NEWGEN AutoDialer: A Windows program that dials up the NEWGEN RTU and lets you view and download information from them.  While on site you can also connect directly to the controller with a serial cable.  Eventually it will become a complete remote site management tool for field service personnel and central site management personnel. If you have a remote site with process control, electrical generation or switchgear monitoring, or unmanned pumping and treatment stations, this is a cost effective solution.     back to main page
