Operator control station
March 2013
PLCs, DCSs & Controllers
The operator control station (OCS) combines a controller, operator interface, network and I/O into a single product and is comparable with a mid-sized PLC in terms of performance. Programmed by a single, powerful ladder logic software package, users can develop HMI screens as well as the control functions within the same software. Cscape simplifies the programming task by eliminating the need for two software packages as commonly associated with programming PLCs and HMIs.
Most of the products also feature the CAN port which can be used in either CsCAN or CANopen mode. Horner standard, called CsCAN, provides a powerful network to other units or scada at a minimal cost and provides a single point of connection to the network for programming, monitoring and troubleshooting. CANopen is an industry recognised standard that enables the connectivity options to third-party equipment, like drives and I/O modules. In addition to the CAN protocols, support is provided for serial Modbus RTU Master and Slave. Ethernet versions are also available that provide three common protocols including Modbus TCP/IP.
Users can choose from small text-based screens to large colour TFT screens, all integrated with the controller as one product and easily programmed. Extensive I/O range encompasses both digital and analogue modules. Smartstack I/O Modules, controlled by Maths Script Language, can be added to our larger units thereby enhancing their capabilities.

Seven checks before replacing an obsolete industrial control component
PLCs, DCSs & Controllers
