8.4 Input/lDutput diagram for machine parameters
Machine parameters are either keyed or read into an empty memory (commissioning or control exchange) or
altered at a machine with the control installed (e.g. switchover DIALOG/ISO).
Machine parameters should always be stored on an external data medium so that they can be read-in via the
RS-232-C/L/.24-data interface at any time.
With an empty MP-memory, the control displays the following message after power-on:
OPERATING PARAMTERS ERASED
After cancelllation of the message via
0
CE , the request for the entry value MPO is displayed
MACHINE IPARAMETER MPO ?
Entry is now performed either manually or via the RS-232-C/V.24 data interface.
Please note
With read-in, the data transmission mode ME-FE-EXT is to be set corresponding to the external storage
unit. This is carried out via the
0
MOD -key.
8.4.1 Readl-in of machine parameters when memory is erased
Read-in of machine parameters is possible in the ME-mode with the ME 1 Ol/ME 102 magnetic tape units
or the floppy disc unit FE 401.
Before data transmission, check MOD-function for correct operating mode.
With FE 401 read-in of machine parameters is also possible in the FE-mode, if these can be called-up via
a program number.
If another peripheral unit is being used instead of the ME or FE, the adaptation as per ME-operation is
performed in the EXT-mode, however, another Baud rate can be programmed via the MOD-function.
If the check-sum of the machine parameters is erroneous, the optional dialogue language is always selected
as per the NC-software number after "Reset".
The memory in which the machine parameters are stored can be erased via the following code number:
Code number 531210 - Erasing of machine parameters
Simultaneously, PLC-markers M 1000 to M 2000 are reset.
Read-in of machine parameters via the RS-232-C/V.24-interface
When reading-in machine parameters, comments which are designated by "*" or ",I' are ignored.
