4.6.2
Configuration
During configuration the user can define what modules are required and in which order the data is transferred. The
unit simply adds the input and output data bytes to the message maps in the order that they are defined in the
configuration message.
Example:
Module = Mod_A 3 bytes in (Ai1, Ai2, Ai3), 1 byte out (Ao1)
Module = Mod_B 2 bytes in (Bi1, Bi2), 2 bytes out (Bo1, Bo2)
A)
Configure Mod_A, Mod_B gives
Output map: -
Input map: -
B)
Configure Mod_B, Mod_A gives
Output map: -
Input map: -
Data is always referred to the Master so output data is Control data from Master to Slave and Input data is feedback
data from Slave to Master.
There are many software modules, (TIC has 28), and many bytes of data (TIC has up to 95 input bytes), care must be
taken in correctly selecting and aligning the data into your system.
Configuration may take up to 5 seconds to occur. During this period the Profibus Slave will signal to the Master that
is is "not-ready" for data exchange.
4.6.3
Configuration failure
Some variants of the TIC do not have all functional items present and the modules related to these items will not be
valid. An inappropriate configuration will lead to parameterisation or configuration failure and the slave will not
enter data exchange. The number of the first failed module will be placed in the extended diagnostic data. See GSD
or
for description of the extended diagnostics.
4.6.4
Parameterisation failure
Some parameterisation will not be valid in particular combinations. The TIC and/or DX will determine this and the
Slave will not enter data exchange. The number of the first failed module will be placed in the extended diagnostic
data. As per current recommendations this is not flagged as a critical diagnostic in the mandatory diagnostics (octet
1 bit 3).
