Remote operation

9.2 Status

Cyclic data transmission
Cyclic data transmission transfers the user data relevant for process automation between the
Class 1 Master (control or automation system) and the transmitter.
When you configure Pointek CLS200/300 on the PROFIBUS PA bus, there is one slot available
for modules, and the Level Status module is automatically inserted.
Transmission of user data via PROFIBUS PA
The user data is continuously updated by the cyclic service of PROFIBUS PA. The user data is
the OUT parameter of the Discrete Input Function Block and is composed of the Logical Level
and Status bytes.
The 2 bytes must be read consistently
by byte, and must not suffer an interrupt. If you are using an S7-300 / 400, you will need to
use SFC14 DPRD_DAT: Read Consistent Data of a Standard PD Slave.
