Press Release CamCon DC190

At Siemens, the change from the Simatic S7-300 and Simatic S7-400 controller generation to the next generation called Simatic S7-1500 is imminent.

Although the latest generation of controllers will have a fast counter module, this will only have a very limited cam switch functionality. For time-critical tasks, manufacturers of packaging machines, filling and labelling machines, printing machines and presses still require the functionality of an electronic cam controller in the form of separate hardware with very fast and, above all, constant cycle time.

Digitronic's latest electronic cam controller CamCon DC190 offers an Ethernet interface for communication with PLC controllers from various manufacturers. For the exchange with the Simatic S7-1500 the protocol PROFINET is integrated in the CamCon DC190. This means that cams can be programmed, cam or product programmes can be changed, speed compensation values can be adjusted and, if necessary, the system parameters of the electronic cam switch unit can be read and written from the Simatic control. This is all done using the supplied handler and data modules.

The constant cycle time in the fastest application parameterisation is merely 80μs (microseconds). In these 80μs, the position and speed are recorded by the connected displacement encoder and the 32 digital outputs including channel-wise speed compensation are switched.

Since the Simatic S7-300 and Simatic S7-400 product lines will be replaced by Siemens in the future, machine builders will have to equip the next generations of their machines with the Siemens Simatic S7-1500 if they rely on the control system supplier Siemens. The transition will also be accompanied by a significant increase in the purchase price of the existing controls.

Digitronic now solves this problem for machine-builders with the CamCon DC190. It has 32 outputs 24 VDC onboard with a respective load capacity of 500mA per output, based on a simultaneity factor of 100%.

An additional 16 digital inputs are available to the user for direct linking in the DC190 with sensors, actuators, buttons, control elements and the like. These links have no effect on the cycle time and enable product queries in the production process using optical sensors, manual operating functions and safety interlocks. For path detection, 2 inputs for SSI absolute encoders or 1 input for incremental encoders 24 VDC are available.

The parameterisation and programming of the CamCon DC190 is done either by handling blocks in the Simatic S7 or through the Digitronic programming software Digisoft CamCon WEB.

Especially for production and packaging plants of hygienic products several angle synchronous shift registers are available to guarantee product tracking during the production process. A special software package for press control and punch automation with integrated digital and analogue cam outputs, press force monitoring and tool protection is also available.
