4. Communication with the module
4.1Addressing
a) Rotary address switches
Two rotary switches, located above the M12 bus con
nections behind a clear cover, are used for direct
adjustment of the Profibus address. The switches for
setting the tens and the ones of the address are indi
cated. After selecting the address via the rotary switch
es the address will be set internally after power is
applied to the module. Therefore the power supply
must be interrupted briefly if the address is changed
during poweron in order to allow the module to adopt
the new address.
b) Profibus network
It is also possible to adjust the settings of the module
address via the Profibus network. Precise directions
regarding procedural method can be found in the man
ual for your respective Profibus Master.
4.2Data transmission rate
The data transmission rate used is established at the
start of communication between the module with the
master, and is automatically detected (AutoBaud
Detection).
4.3 Examples for integration into the control
system configuration
The configuration file (gsd file) of the modules must be
integrated into the control system software. The precise
procedural method can be obtained from the manual for
the respective control system.
The following examples show the procedure for the S7
software of the Siemens Company and the CoDeSys
software of the 3S Software Solutions Company.
The adjustable address range lies between 1 and 99.
The factory setting for the address is 99.
The rotary switches must be set to the value "00" to allow
software addressing. The addressing range in such cases lies
between 1 and 126.
The determination of the Profibus address and the range of
the input and output bytes is automatically set by the
respective configuration software, but can also be altered by
the user.
