4.1.3 Changing the standard parameters
The interface module is automatically parametrized after the PLC has been switched on for the first
time. The following standard values are set:
•= Standard function (without a procedure/protocol)
•= Baud rate of 9600 baud
•= Even parity
•= Start bit
•= 8 Data bits
•= 2 Stop bits
•= All buffers are reset
•= Error-LED is switched off
The FB5 or the FB15 are required for changing the standard values. The FB102 or the FB103 are
required, if one wishes to set the internal clock..
4.1.3.1 FB5 (PARAMETR), parametrizing
With the FB 5 (PARAMETR) it is possible to alter the standard parameter.
It is advisable to load the FB 5 (PARAMETR) when restarting (OB 20 ... 22). FB 5 should be
reloaded once for each channel.
Please use FB 15 for peripheral addressing.
The FB is not required, if standard parametrizing should be used.
The following parameters are to be transferred when loading FB 5:
Des. Format Explanation
ADR KH Building block’s absol. base address
K/0 KY Number of channels
BAUD KF Baud rate code
ZEI KF Bit / Character
PARI KY Parity code
STOP KF Number of stop bits
FEHL BY Error byte
Tab. 4-2: List of parameters for the loading of FB 5
The following details are necessary for the abovementioned parameters:
ADR
(absolute)
Input of the physical start address, under which the module can be accessed by
the PLC. This start address can be set with the DIL switches S1 and S2.
In the case of peripheral addressing, enter the address, which you have set with
the S1 switch on the building block, into the FB 15. You can load the following
addresses: BG41: PY128-PY252, BG42 and BG43: PY128-PY248
