Deactivation of the PROFINET IO function
1065863563
If the SP-COP2-ENI device is started with an activated PROFINET IO function, then this func-
tion remains active until the device is switched off.
For this reason, switch the device off after sending a project without PROFINET IO function.
This is required, for example, if you convert the gateway function in the samosPRO project
from PROFINET IO to Modbus TCP.
State bits
1179305611
The PROFINET IO gateway SP-EN-PN sets state bits, which are available in the logic editor of
samosPLAN5+ for processing.

Name of the state bits
Set to 1, if ...
Reset to 0 ...
Output state … Data from slot 16, 17, 18,
19, 20, 32 or 33 was transmit-
ted without error.
… No AR (Application Relati-
on) exists.
Input state
… Data from slot 21, 22, 23, 24
or 25 was downloaded from a
PLC without error.
… No AR (Application Relati-
on) exists.
Internal state … An AR (Application Relation)
is active.
... No AR exists.
An Application Relation (AR) is a clear communication relationship between two communicati-
on partners, for example a PLC and a device. The AR is initialized during PLC start-up. Cyclical
input and output data, acyclical data using read/write services and alarms are exchanged bidi-
rectionally between the PLC and the device within this AR.
