“I recommend the CTI 2500 Series migration solution for a 5TI PLC. We only had to replace the failed component and it was the most seamless control system migration project I have experienced”

Alan Wilkes

Managing Director

The 5TI was released by Texas Instruments in 1974, and thirty four years later a large number of units are still controlling machines around the world. One such installation is on a Husky injection moulding machine used by Queensland Blow Moulders in their Lytton factory. After decades of reliable service the 5TI processor has developed an intermittent fault that changes the preset values of certain timers resulting in machine malfunctions, wasted raw materials and production loss. Needing technical assistance they contacted CT Oceania.

The first solution attempted was to procure a second hand 5TI processor. CT Oceania used its network of contacts to locate a 5TI processor and assisted in the installation and configuration of this replacement unit. After only a few days production, the newly installed unit failed and the original unit with the intermittent fault was installed until another solution is found.

CT Oceania submitted a proposal to management to replace the 5TI processor with a new CTI 2500 Series processor. Managements’ main concern with attempting a migration was based on experience from previous control system migration projects that resulted in extended periods of downtime as bugs and issues are resolved before consistent full production can be achieved. CT Oceania presented to management that

Contact CT Oceania for information on the CTI 2500 Series migration solutions for 5TI, TI505, TI525, TI535, TI545, TI565, TI575 and Series 505 PLC platforms. Our customers’ experiences have proven that the CTI 2500 Series migration solution for these PLC platforms is the easiest, most automated, lowest risk, and typically a tenth of the cost of other solutions available today.

1974 to 2008 in 48 hours: A 5TI migration project

unlike other migration options available, the CTI 2500 Series based solution is very low risk and cost because:

1. Whilst the program conversion is manual it is simply a data entry exercise as the CTI 2500 Series supports the 5TI’s ladder instructions. This avoids the time, cost and risk associated with redesigning a program. PLC Workshop for 505 provides the rapid application development environment required to complete this task.

4. The existing timer/counter interface is easily replaced with a Parker XPR 6” HMI touch screen. The improved HMI interface will reduce the time it takes an operator to change machine settings.

The entire migration project took less than 48 hours to complete. The installation, commissioning and training stages took less than four hours and once the machine was warmed up it has been running at full production.

Queensland Blow Moulders are very satisfied with their new control system that offers all the benefits, performance and features expected of a modern PLC platform. They are looking forward to uninterrupted operation of their Husky machine well into the future.

2. The CTI 2500 Series interfaces with the 5TI’s I/O modules eliminating the risk, time and cost associated with modifying, testing and documenting new wiring. Should a 5TI I/O module fail in the future it will be replaced with CTI 2500 Series I/O, requiring changes to the PLC I/O configuration and wiring but not the program.

3. The four slot CTI 2500 Series rack will occupy the 5TI’s space in the cabinet so no cabinet modifications are needed.
