Channel changeover

1...n

The SINUMERIK 810T has 3 channels:

·By pressing this key once, you change to the next higher channel number compared with the number presently displayed.

·By pressing the key again, the next channel is selected, etc.

Channel structure:

The 3 channels mean:

Channel 1: Main channel for executing part programs and spindle programming

Channel 2 : Auxiliary channel for executing programs for

additional axes or for computational functions in the background., Channel 3 : Graphic simulation for program representation on the screen.

(Note: the ºGRAPHIC SIMULATIONº function can be ordered as an option.)

In addition to the other structural operations such as program editing and interface control parallel to processing, the channels make simultaneous processing of two different programs possible.

It is basically possible to operate all 3 channels at the same time. However, in the case of a few functions collision problems will occur.

· Blueprint programming · TNRC

·Auxiliary function display

·NC-PLC data

Channel 1

Channel 2

Channel 3

Except for the functions which are not implemented, the auxiliary channel (channel 2) is a full channel. The main task of this channel is to carry out calculations which are running in the background or to execute auxiliary movements. (e.g. tool change, ...)

One and the same axis can be moved in channel 1 and channel 2 if it can be ruled out that a drive command is given from channels 1 and 2 at the same time (....Alarm 180*:ºAxis programmed in both channelsº.)

The main function of the auxiliary channel (operated from the PLC simultaneously with the main channel) is however to operate loader axes. Under the above-mentioned conditions it is possible, however, to implement other concepts using the auxiliary channel, so that a wide range of applications is possible.

As it is only possible to transfer M-functions from channel 2 to the PLC, the possibilities for data exchange are limited.
