DOLD bus modules

Increasing complexity of control systems in machines and plants and a strong tendency to decentralization induced by an increasing use of intelligent subsystems explain the boosted communication needs between control and peripheral systems in todays machine and plant control. Ever-growing data amounts require a high-performance bus system which is able to transmit large bulks of data between intelligent control elements in a reliable and quick manner. 

Input and output modules (I/O modules) are peripheral modules of a PLC in the bus system: Input modules collect information on the processes to be processed. Via the bus system data items are transmitted to the control unit where they are processed. 

Again via the bus network control commands are transmitted to the output modules which pass them on to the actuators. Both analog and also digital DOLD bus modules for the CANopen field bus system are available. We also offer Suconet-compatible devices.
