The Acromag range of Profibus I/O modules feature universal input/output ranges and an intelligent micro controller offering flexibility and powerful monitoring and control capabilities.
The modules provide direct network interfaces for I/O signals. Unlike 'block I/O' devices that combine a large and expensive processor block with snap-on I/O terminal blocks, the Acromag 900PB modules handle the network interface and I/O processing in a single, compact multichannel module. This space-saving approach (only 26 mm wide for six channels) is cost-effective for systems that need to add some I/O channels at an existing control site or new network, remote sites. Isolated input, output, power, and network circuits increase noise/transient immunity and prevent ground loops. Status LEDs provide diagnostic feedback.
Self-diagnostics and watchdog timers simplify maintenance and troubleshooting. The watchdog timer invokes a failsafe condition if host communication is lost. For further security, a second watchdog monitors the micro controller for failed operations or a lock-up condition and automatically resets the unit.
Introduction to Part 2 loop signatures and process transfer functions
Fieldbus & Industrial Networking
The previous series of loop signature articles dealt with the basics of control loop optimisation, and concentrated on troubleshooting and ‘SWAG’ tuning of simple processes. In this new series, consideration will be given to dealing practically with more difficult issues like interactive processes, and with processes with much more complex dynamics.
