CP 523
System Overview
System Overview
Intelligent
modules (1/0s) expand the application area of 51
programmable
controllers.
They are technology-oriented and offload the central processing unit by preprocessing
input signals.
The
523 serial
module is an intelligent
module, which can be used in the
15U,
S5-150U, S5-155U and
15F programmable controllers. It can be operated without
special COM software and offers applications which until now could only be implemented with
expensive and functional y complex modules.
The
523
can be used in “Print mode” and “Communications mode”. It has
a
built-in real-time
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
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
●
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.)
