PROFIBUS is not in the data transfer condition
The PROFIBUS is not in a data transfer status (data exchange) or data
transfer was interrupted.
Causes:
– The master has not yet run up, or has not yet established a
connection to the slave.
– The bus addresses differ in the master configuring and slave
parameterization.
– The bus connection has been physically interrupted.
– The master is still in the clear condition.
– An illegal parameterization or configuration was received.
– A PROFIBUS address was assigned several times.
Master, check the assignment of bus addresses and bus connection.

PROFIBUS not clock-synchronous with the master
The PROFIBUS is in a data transfer status (data exchange) and has been
selected via the parameterizing frame of synchronous operation. It could
not yet be synchronized to the clock preset by the master resp. to the
master sign-of-life.
Causes:
– The master does not send an equidistant global control frame
although clock synchronism has been selected via the bus configuration.
– The master uses another equidistant DP clock cycle than was
transferred to the slave in the parameterizing telegram.
– The master increments its sign-of-life (STW2 Bits 12–15) not in the
configured time frame Tmapc.
Check master application and bus configuration
Check the consistency between the clock cycle input for the slave con-
figuring and the clock cycle setting at the master.
If the master (e.g. SIMATIC S7) does not transfer a sign-of-life, the
sign-of-life evalution can also be suppressed using P0879 bit 8.
