Module state
The samosPRO gateway can transfer the state of the linked modules to the network. A total of 4
bytes are available for this purpose.

Input values for I/O modules
1 byte for data set 1 is available for every expansion module. The input values show the state of
the preliminary evaluation of the I/O module. This corresponds to the state of the element in the
controller module logic. The level at the associated terminal cannot be clearly detected from
this, as the data may be set to low, irrespectively of the level at the input terminal, by means of
the cross-connection detection or two-channel evaluation (e.g. I1-18).
When two-channel input elements have been configured for an I/O module, only the lower-
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):
