Introducing Transition Networks' new RS485 remotely managed copper to updated RS422/485 converters for the Point System chassis fibre media converters. These products are a complete re-design to our old RS485-CF-0x series of converters.

The new product includes the following updated features:

* Standalone or Point System card form factors.

* Remote management of standalone converter.

* Single-mode transmissions distances up to 40 km.

The serial RS422/485 to fibre media converter allows you to extend the distance between serial connections with the use of fibre-optic cable. This full-featured converter operates in 2-wire mode for RS422 and either 2-wire or 4-wire mode for RS485 and supports full or half-duplex data transmission at speeds up to 1,25 Mbps.

These are suitable for linking a remote terminal to a host computer, connecting multiple devices, such as security scanners, POS devices, remote terminals and building access/alarming systems to a host computer. These converters are also suitable for campus or business environments where remote devices can be networked in either a point-to-point or point to multi-point configuration. Note that the new converters are not a direct replacement for the old RS485-CF-0x series - the different optical transmission wavelengths, and updated features have meant that the new products are not backward compatible with the old.

Case history 189: Poor furnace temperature control.
Michael Brown Control Engineering Editor's Choice PLCs, DCSs & Controllers
Many process engineers do not appreciate the importance of flow loops in their unit controls. A senior process engineer once told me that flow loops need not be tuned well, as they generally have little effect on the more important and much slower loops like temperatures and pressures.

PLCs and PACs simplify data acquisition
PLCs, DCSs & Controllers
Data acquisition, data logging and data analysis are required functions for most modern industrial control systems. The simplest and lowest cost way to provide these functions is often by using the same platform that’s providing real-time control, namely the PLC or the programmable automation controller.
