value bit represents the pre-evaluation state of the corresponding element (e.g. bit 0 for I1 and
I2, bit 2 for I3 and I4, bit 4 for I5 and I6, bit 6 for I7 and I8). The higher-value bit (bit 1, 3, 5 and 7) is
used as follows in this case:
0 = error 1 = no error

Output values for I/O modules
1 byte for data set 1 is available for every module with outputs. The output values indicate the
state of the control information from the logic of the controller module for the relevant element
of the I/O module. The level of the associated terminals cannot be clearly detected from this, as
the output may be switched off via the cross-connection detection or the overload connection
function.
When two-channel output elements have been configured for an I/O module, only the lower-
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
77547787
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 net-
work (e.g. to a PROFIBUS master) and vice versa.
Configuration test values (CRCs)
77557259
Data set 2 contains the following configuration check values of the samosPRO system:
• Project CRC of the project file created with samosPLAN
6
• System-CRC, uniquely assigned to a module version, consisting of internal software and hard-
ware 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.
