Tc_Config For Changing Configuration Data Of The Cp - Siemens CP 1243-7 LTE Operating Instructions Manual

Program blocks

5.3 TC_CONFIG for changing configuration data of the CP

Length information at "LEN" and "DATA" for the blocks "TRCV" / "TRCV_C"
When receiving SMS messages via the blocks TRCV or "TRCV_C" if you enter length
information in the "LEN" parameter, this can lead to incorrect information in the data storage
of the received information.
Recommendation: Set LEN = 0 and enter the length information in the "DATA" parameter.
Character set for the SMS text
The CP supports the following ASCII character set (hexadecimal value and character name)
for SMS message texts sent via program blocks:
● 0x0A
LF (line feed)
● 0x0D
CR (carriage return)
● 0x20
Space
● 0x21 ... 0x5A
! " # $ % & ' ( ) * + , - . / 0 1 2 3 4 5 6 7 8 9 : ; < = > ? @ A B C D E F G H I J K L M N O P
Q R S T U V W X Y Z
● 0x61 ... 0x7A

5.3 TC_CONFIG for changing configuration data of the CP
Meaning
With the program block TC_CONFIG , you can modify parameters of a the CP configured in
STEP 7. The configured values are not overwritten retentively. The overwritten values
remain valid until TC_CONFIG is called again or until the station starts up again (cold restart
after cycling power).
If the STEP 7 configuration data of the CP needs to be changed permanently, the block
needs to be called again each time the station restarts (cold restart) or a modified project
must be downloaded to the station.
The CONFIG parameter points to the memory area with the configuration data. The
configuration data is stored in a data block (DB). The DB cannot be created with optimized
block access. The structure of the DB is specified by the system data type (SDT) IF_CONF.
The configuration data to be modified on the CP is put together as necessary in blocks in
IF_CONF "IF_CONF_..." for the individual parameters.
Parameters that are not intended to change as a result of the block are not entered in
IF_CONF. They retain the value configured in STEP 7.
