Programmable
Logic Controllers manufactured for
Industrial Automation

Our 2500 Series® PLC system is a compatible replacement for the former Simatic® 505 PLC system, and includes state-of-the-art enhancements in functionality and performance. Products in the family include controllers, power supplies, bases, remote base controllers, analog and digital I/O, ethernet TCP/IP, Modbus, DeviceNet networking modules and specialty I/O modules. CTI 2500 Series® products are installed in the plants of major industrial companies throughout the world.

And with the New Janus CPU and the ACP Modules CTI is moving into industry 4.0 with communications using Ethernet/IP, OPC-UA, MQTT, Modbus TCP and Profinet (Future) covering all the major communications along with still being able to use Camp, Profibus and Modbus Serial (as always being backwards compatible).

CTI has also developed new software called Workbench which can be used to program the Janus and ACP cards. Using more modern programming languages (IEC 61131-3 Languages

Instruction List (IL), Structured Text (ST), Ladder Diagram (LD), Function Block Diagram (FBD) and Sequential Function Chart (SFC)) this will now bring CTI up to date with current programming techniques and communications whilst still keeping the fundamental aspects of what CTI stands for of always being backwards compatible.

Frequently asked QUESTIONS

Our Systems Integrators told us that Siemens 505 and 500 Series were obsolete and we would need to replace them?
CTI took over from Siemens for making 505 and 500 series modules. In the 2000’s CTI had developed replacement cards for both Siemens Series 505 modules as well as 500 modules which includes an adaptor (2500 Series). This series is not obsolete and will continue to be supported and developed into the future. We also have a conversion tool to determine which replacement part is required. Please contact to discuss further
Does CTI product have chip supply issues?

There have been no real effects to supply due to the modules being manufactured in the USA.

How often should a Power Supply be changed?

Power supplies should be changed every 7-10 years for a processor or when a new processor is installed and every 10-15 years for remote base rack.

Can you program CTI 2500 series (Siemens 505) using the IEC 61131-3 Languages

CTI has developed and released the Janus CPU which can be programmed in any of the IEC Languages using the new Workbench Software. The new CPU is still backward compatible with existing IO
