General

The CP 521 enables the output of message texts to a printer in print mode:
• Output of message texts defined by you in the memory submodule in data
blocks (DB) 2 to 63.
• Insertion of the current time of day and date in the message text to be
printed out. The clock data is supplied by the integrated real-time clock.
• Insertion of current variable in the printout.
The variable values can be transferred from the CPU to the CP 521.

Prerequisites for Operating in Print Mode

The following conditions must be met in order to operate the CP 521 in print
mode:
1. Printer settings
The printer settings must agree with the your configured settings in the memory
submodule in the parameter blocks of DB 1. If you have set a baud rate of 1200
baud on the printer, for example, you must set the same baud rate in DB 1.
Note:
Set the parameters for the serial interface on your printer as desired and then
set the parameters in DB 1 in the memory submodule.
• See 3.5.1 for configuration examples with terminal diagrams.
• Parameter setting in DB 1 is explained in 6.3.
