wer-value bit represents the control information (e.g. bit 0 for Q1 and Q2, bit 2 for Q3 and
Q4, bit 4 for Q5 and Q6, bit 6 for Q7 and Q8). The higher-value bit (bit 1, 3, 5 and 7) is not
used as follows in this case (low):
Transmission of data from a second network
910747531
If your samosPRO system contains two gateways, it is possible to forward information which
the first gateway receives from a network (e.g. from a Modbus PLC) via the second gateway to
a second network (e.g. to a PROFIBUS master) and vice versa.
Configuration test values (CRCs)
910749067
Data set 2 contains the following configuration check values of the samosPRO system:
• Project CRC of the project file created with samosPLAN5+
• System-CRC, uniquely assigned to a module version, consisting of internal software and
hardware version
The CRCs are each 4 bytes in length. Data set 2 can be read only.
The project CRC with Modbus/TCP is transmitted in Big Endian format.
The system CRC is available from module version B-01.01 for PROFIBUS DP and EtherCAT.
Error and state information for the modules
910750603
Data set 3 and 4 contain the state information for the modules that will be transferred to the
network.
Ten bytes are transmitted for SP-COPx controller module. For each SP-SDI and SP-SDIO I/O
module, four bytes are transmitted in the Little Endian format, e.g. as a 32-bit word, with the
first byte being placed into the least significant byte of the whole number (extreme left) and
the fourth byte into the most significant byte of the whole number (extreme right).
Data sets 3 and 4 cannot be adapted.
Module state bits of the controller module SP-COPx
The module state bits have the following meaning, if not otherwise indicated:
0 = error
1 = no error
Reserved bits have the value 1
