The optional redundancy of processor modules provides high availability solutions for process control. The automatic and seamless changeover of the processors, together with the live replacement of processor modules, prevents any interruption of the process.
The T940X supports peer-to-peer communications using LIN over ARCnet (ALIN) or Ethernet (ELIN) providing a real distributed control system.
The Process Supervisor’s support for Profibus (DP and DPV1) and Modbus RTU provides a truly open I/O network allowing connections to the process interface (2500) I/O modules and other third party devices.
Separating the processing from the I/O allows physical distribution of the modules which reduces wiring installation costs.
An extensive function block library is available that includes control, batch, timing, math, logic, conditioning and control modules, while Sequence Function Charts (SFC) can be used for more advanced sequencing.
Online reconfiguration of the database can be tried out and deleted as required - the final modifications can then be applied. All carried out without halting the application or the process.
