CP 521
7.3
Setting the CP 521 Parameters in ASCII Mode
The CP 521 is supplied with default values for the parameter setting data.
•
Parameters for the interface to the peripheral device (baud rate, type of
interface, handshake mode ...)
•
Specifications of the XON/XOFF protocol
•
Parameter setting data for data transfer in ASCII mode (message length, end--
of-text character).
If you want to set other CP 521 data, there are the following other ways of
transferring parameter setting data to the CP:
•
Transfer the parameter setting data to the CP 521 in the user program
( 7.3.1)
No memory submodule is required for operating the CP 521
•
Store the parameter setting data on a memory submodule in data block (DB)
1 and plug the initialized memory submodule into the CP 521 ( 7.3.2).
•
Transfer the parameter setting data with the "FORCE VAR" programmer
function.
No memory submodule is requirerd to operate the CP 521.
In order to transfer the parameter setting data as simply as possible, the
parameter setting data are divided into parameter blocks. This subdivision is the
same as in print mode. Parameter blocks 1, 3, 4, 5 and 6 are not significant in ASCII
mode and are not included in the table.
