input signals.
The CP 523 serial 1/0 module is an intelligent !/0 module, which can be used in the S5-1 15U,
special COM software and offers applications which until now could only be implemented with
expensive and functional y complex modules.
The CP 523 can be used in "Print mode" and "Communications mode". It has
clock, which can be backed up by the battery of the power supply unit. The clock data can be read
by the CPU and used in the user program for date-dependent and time-dependent tasks.
Print mode
Message texts can be printed out in this mode. This allows you to list process states and process
-
faults.
. Printers with TTY or RS-232-C (V.24) interfaces can be connected
The printer interface can be configured (baud rate, BUSY signal, etc.)
The format of the page to be printed can be configured (headers, footers, margins, etc.)
. Configuration of up to 4095 different message texts in data blocks on a memory submodule
You can provide for the following when configuring message texts:
Insertion of the date or time of day in the printout
Insertion of current variables in the printout (pressure, temperature, etc.)
Transfer of printer control parameters (double-width type on/off, boldface type, etc.)
