R. STAHL enhances IS1 remote I/O system

May 12, 2010 - R. STAHL's IS1 remote I/O solution is now capable of EtherNet/IP communication. The solution, which was limited to the Modbus TCP protocol up to now, has become more flexible. EtherNet/IP paves the way into the world of Rockwell- and Allen Bradley-compatible systems and interfaces, which are supported by most PLCs and control systems. Fulfilling strict real-time requirements, the protocol has a key advantage over Modbus TCP. Users can configure and parameterise the system by means of a high-performance DTM which also provides a wide range of diagnostic functions and enables condition monitoring.R. STAHL now also provides more installation flexibility for the proven IS1 PROFIBUS versions. Due to great demand, the company had already developed proprietary solutions with line and system redundancy. Additionally, IS1 is now also available with a system redundancy compliant with the “PROFIBUS Slave Redundancy” specification. In automation systems which support this standardised solution, IS1 runs as a redundant slave. Today, these systems mainly include controllers from Siemens and ABB. In order to provide a driver-independent, standardised redundancy solution for users employing other control systems, R. STAHL has designed a universally applicable implementation. Virtually all other systems can be operated with IS1 in a fully redundant layout with a so-called “Flying Master” redundancy. Successful tests have already been carried out with the Delta V control system from Emerson Process Management and with Centum VP from Yokogawa. The IS1 remote system for hazardous areas, which has been claiming market leadership in zone 1 installations for a long time, asserts its technological leadership position with its new extended functions. The Ethernet platform will also ensure support for the upcoming high-performance process automation protocols PROFINET and FOUNDATION fieldbus HSE. Furthermore, R. STAHL will also pursue up-to-date developments for standard PROFIBUS DP installations.
