RCC controllers combine control, I/O, and networking into a single, integrated package.  They are equipped with a range of digital and analogue built-in I/O. Additionally, most RCCs contain RS-232 & RS-485, CAN and 10/100 Ethernet – which provides you with serial connectivity, I/O expansion, Ethernet communications and advanced functions such as e-mail and web serving.

Use the RCC’s built-in serial and Ethernet ports for Cscape programming. Utilise Horner’s user-friendly, ladder-logic based PLC software, our IEC 6-1131 options, and application defined communications. Data logging, application updates and advanced recipe handling are made easy via the built-in removable microSD memory card.  Log process based on individual events or specific times; everything is completely customisable – create virtual black box functionality for your machine.

Register RCC controllers with Horner webOCS products to monitor and control plant data from the palm of your hand. Published directly from the OCS Controller, the webOCS line allows the same or unique web pages to be monitored and controlled from your computer, tablet or other mobile device.
