Data input/data output

For the input and output of data you will find a RS232C (V.24)/20 mA interface (=Interface 1,
with variable device connections possible) on the front of the operating panel.
A further RS 232 C (V.24) interface (=Interface 2, with fixed assignment for the connection of
a particular device) is located at the back of the control.
The second RS232C (V.24) Interface is only available
Fixed interface data are defined for the interfaces. These data can be modified by calling the
"SETTING DATA" function.
Modification of the interface data - especially for interface no. 1 - is necessary for example,
when a different device is interfaced to the SINUMERIK 810M (printer, tape reader,
programmer, etc.)
You will find the necessary information for setting/modifying the setting data bits in Section
3.1.15.1 (Setting data bits) and Section 6.3 (Assignment of the setting data for the connection
of peripheral devices).
3.1.15.1 Setting data bits
The setting data - from byte No. 5000 (to 5029) - each consist of 8 bits: No. 0 to No. 7.
These setting data serve for the matching of Interfaces 1 and 2, for the connection of different
devices.
Explanation of setting data - structure:
(e. g. for setting data (SD) 5011)
5011
1 1 0 0 0 1 0 0
7 6 5 4 3 2 1 0
Setting data no. Bit pattern of the byte
of setting data 5011
Using an input form on the CRT you can enter/modify the desired bit pattern for any byte in
the range 5000 . . . to 5029.
