Pneumatic equipment comprehensively catalogued
Festo has launched a customised new catalogue, entitled 'Premier Products and Services 2001', covering essential items from the entire Festo product range.
"With these additions we are liberating machine builders to disperse precise amounts and types of I/O exactly where they need them on the machine, for ultimate cost effectiveness," comments Jacqui Reid of Festo.
"This terminal's architecture gives machine builders a license to design networks how they want them.
It makes the automation components fit the machine, and not vice versa." One key new introduction is an extension interface to the CPX terminal's local bus that allows satellite I/O modules to be installed up to 10m away - but without the cost of an additional fieldbus communications module.

Cylinders offer zero rotation under torque
Automation specialist Festo has announced a new range of precision cylinders with integrated guides to offer zero rotation under torque loads and minimal deflection under lateral loads.
Called CP Interface, it supports both electrical I/O and pneumatic solenoid valves.
The interface can be used to provide a few I/O points needed in a particular remote location, or even for large-scale process and production automation systems as up to 512 I/O channels can be dispersed.
Satellite I/O subsystems can be fully environmentally protected, just like the host CPX terminal, to IP65 for the pneumatic valves and IP67 for the electrical I/O.
Diagnostics capability is also complete, with visibility right down to individual channels.
"The new satellite I/O capability can shave meaningful amounts from the automation bill of materials - saving around GBP 200 for every fieldbus interface eliminated for example" adds Reid.
"It also gives engineers the ability to install precisely-proportioned pneumatic valves just where they want.
A distributed CPX terminal can have one kind or size of valve for example, while its satellite I/O module has another." New industrial network communications options add a further dimension to the CPX I/O terminal's capability.
Already compatible with a wide range of fieldbuses including CANopen, CC-Link, DeviceNet, Interbus-S and Profibus-DP, Festo will be extending the choice of Ethernet networking protocols.
The existing TCP/IP and Modbus/TCP options will be joined by the EtherNet/IP protocol - for direct connectivity to the ODVA Ethernet environment.
This will be particularly popular with machine builders who use Allen-Bradley and associated equipment and controllers.
In addition to functioning as remote I/O modules, CPX terminals can be specified with local intelligence.
This option supports even further architectural freedom, with the choice of decentralised control or intelligence, for set up, diagnostics and recovery. Request a free brochure from Festo ...
Reid adds: "Festo valve terminals have led the machine building market for the last five years, and I believe this increase in flexibility of the CPX system will ensure that our terminals remain the machine builders' favourite.".
