Compact controllers integrate displays and up to 64 I/O

02 March, 2015

At next month’s Hannover Fair, Siemens will be launching a pair of compact industrial controllers with integrated I/O and displays, as well as built-in measuring, metering and positioning functions. The Simatic S7-1511C, with 32 digital I/O ports, is just 85mm wide and offers a 60ns bit performance, while the S7-1512C, with 64 digital I/O, is 110mm wide with a 48ns bit performance.

The controllers are aimed at applications such as series-production machines. They are said to cost less than modular controllers with separate processors, as well as being easier to stock. Both models have Profinet connections with two ports and an integrated Web server, making them easy to integrate into networks. If required, extra connections be added by using expansion signal modules.

The controllers are configured using Siemens’ TIA Portal, which has been updated to v13 with Service Pack 1. The latest version offers high-performance functions such as variant management. Automatic address adjustment and option handling – centrally, locally, and via networks – are said to open up new opportunities for machine manufacturers wanting to design modular and expandable machines.

The new controllers are the latest additions to Siemens’ Simatic S7-1500 family, which made its debut in 2012. There are now 14 different S7-1500 central processors (six of which have built-in safety functions), covering applications from small series-production machines to complex plants. At the SPS IPC Drives show in 2014, Siemens also unveiled a software controller based on Simatic S7-1500, for use in PC-based automation.
