Printer Output of Error Messages Via a CP 521
If you wish, you can output S5-95F error messages to printer. To do so, you need a CP 521 and
two data blocks supplied with the COM 95F software. These blocks are on file CP521DST.S5D.
Note that blocks DB1 and DB10 are for the CP 521, and may not be loaded into the S5-95F.
DB1 contains the parameters for the printer. These parameters are pre-initialized for a printer with a
V.24 (RS232C) interface as follows:
•
Data signalling rate
9600 baud
•
Parity
Arbitrary
•
BUSY signal
Yes
•
Data format
7 data bits with parity
•
Hardware handshake
No
You must edit DB1 if you are using a printer with other features. You will find a detailed description
in the CP 521 Manual.
DB10 contains the message texts to appear on the printer. These texts are shorter than those used
in the COM 95F software, and consist of error number, primary information and auxiliary information
(see section 15.3.9). For corrective measures, please refer to the Manual (see Table 15-2).
When initializing the system parameters with COM 95F, you must initialize the CP 521 as signalling
module (see COM 95F Manual).
15.6
Forwarding Error Messages to the SINEC L1 Master
The S5-95F can automatically forward system messages to the SINEC L1 master of bus B, thus
providing you with a central point for evaluating, displaying and logging all messages.
When DB1 is initialized accordingly (see COM 95F Manual), the S5-95F forwards each error flagged
in DB254's error stack to the SINEC L1 master of bus B. Non-failsafe frames to the SINEC L1
master have a fixed length of 16 net data bytes. The SINEC L1 master can identify frames as
system messages on the basis of the source slave number and the frame length. (For this reason,
never send user frames with a length of 16 net data bytes from the S5-95F to the bus master).
